The CYBLE-473148-01 also includes additional solder pad connections (“SP”) usedfor debug or testing on the bottom side of the module. Table 2 and Figure 3 detail the solder pad length, width, and pitch dimensionsof the CYBLE-473148-01 module. Figure 3. Solder Pad Dimensions (Seen from Bottom)To maximize RF performance, the host layout should follow these recommendations:1. Antenna Area Keepout: The host board directly below the antenna area of the Cypress module (see Figure 2 on page 4) mustcontain no ground or signal traces. This keep out area requirement applies to all layers of the host board. 2. Module Placement: The ideal placement of the Cypress Bluetooth module is in a corner of the host board with the PCB traceantenna located at the far corner. This placement minimizes the additional recommended keep out area stated in item 2. Pleaserefer to AN96841 for module placement best practices.3. Optional Keepout: To maximize RF performance, the area immediately around the Cypress Bluetooth module PCB trace antennamay contain an additional keep out area, where no grounding or signal traces are contained. The keep out area applies to all layersof the host board. The recommended dimensions of the host PCB keep out area are shown in Figure 4 (dimensions are in mm).Figure 4.

Table 3 lists the solder pads onthe CYBLE-473148-01, the silicon device pin, and denotes what functions are available for each solder pad. Table 3 also lists theprimary/intended function for each solder pad for the application this module was specifically designed for.Connections and Optional External ComponentsPower Connections (VDD)The CYBLE-473148-01 contains one power supply connection, VDD.VDD accepts a supply input of 3.30 V. Table 9 provides this specification. The maximum power supply ripple for this power connectionis 300 mV, as shown in Table 9. Considerations and Optional Components for Brown Out (BO)ConditionsPower supply design must be completed to ensure that the CYBLE-473148-01 module does not encounter a Brown Out condition,which can lead to unexpected funcitonality, or module lock up. A Brown Out condition may be met if power supply provided to themodule during power up or reset is in the range shown below: VIL ≤ VDD ≤ VIHRefer to Table 13 for the VIL and VIH specifications. System design should ensure that the condition above is not encountered when power is removed from the system. In the event thatthis cannot be guaranteed (i.e. battery installation, high value power capacitors with slow discharge), it is recommended that anexternal voltage detection device be used to prevent the Brown Out voltage range from occuring during power removal. Please referto Figure 7 for the recommended circuit design when using an external voltage detection IC.Table 3.

Document Number: 002-23505 Rev. ** Page 8 of 34CYBLE-473148-01Figure 7. Reference Circuit Block Diagram for External Voltage Detection ICIn the event that the module does encounter a Brown Out condition, and is operating erratically or not responsive, power cycling themodule will correct this issue and once reset, the module should operate correctly. Brown Out conditions can potential cause issuesthat cannot be corrected, but in general, a power-on-reset operation will correct a Brown Out condition. External Reset (XRES)The CYBLE-473148-01 has an integrated power-on reset circuit which completely resets all circuits to a known power on state. Thisaction can also be envoked by an external reset signal, forcing it into a power-on reset state. The XRES signal is an active-low signal,which is an input to the CYBLE-473148-01 module (solder pad 3). The CYBLE-473148-01 module does not require an external pull-upresistor on the XRES input During power on operation, the XRES connection to the CYBLE-473148-01 is required to be held low 50 ms after the VDD powersupply input to the module is stable. This can be accomplished in the following ways: nThe host device should connect a GPIO to the XRES of Cypress CYBLE-473148-01 module and pull XRES low until VDD is stable.XRES is recommended to be released 50 ms after VDD is stable.nIf the XRES connection of the CYBLE-473148-01 module is not used in the application, a 0.33 uF capacitor may be connected tothe XRES solder pad of the CYBLE-473148-01 in order to delay the XRES release. The capacitor value for this recommendedimplementation is approximate, and the exact value may differ depending on the VDD power supply ramp time of the system. Thecapacitor value should result in an XRES release timing of 50 ms after VDD stability. nThe XRES release timing may be controlled by a external voltage detection IC. XRES should be released 50 ms after VDD is stable.Refer to Figure 10 on page 14 for XRES operating and timing requirements during power on events.UART ConnectionsFor full UART functionality, all UART signals must be connected to the Host device. If full UART functionality is not being used, andonly UART RXD and TXD are desired or capable, then the following connection considerations should be followed for UART RTS andCTS: nUART RTS: Can be left floating, pulled low, or pulled high. RTS is not critical for initial firmware uploading at power on. nUART CTS: Must by pulled low to bypass flow control and to ensure that continuous data transfers are made from the host to themodule. External Component RecommendationPower Supply CircuitryIt is not required to place any power supply decoupling or noise reduction circuitry on the host PCB. If desired, an external ferrite beadbetween the supply and the module connection can be included, but is not necessary. If used, the ferrite bead should be positionedas close as possible to the module pin connection. If used, the recommended ferrite bead value is 330 Ω, 100 MHz.

This section contains descriptions of the PMU features.Figure 9. Power Management Unit of CYW20719RF Power ManagementFigure 9 shows the CYBLE-473148-01 power management unit (PMU) block diagram that is contained in the CYW20719 silicondevice. The CYW20719 includes an integrated buck regulator, a bypass LDO, a capless LDO, and an additional 1.2 V LDO for RF.Host Controller Power ManagementPower is automatically managed by the firmware based on input device activity. As a power-saving task, the firmware controls thedisabling of the on-chip regulator when in HIDOFF (deep sleep) mode.BBC Power ManagementThere are several low-power operations for the BBC:nPhysical layer packet handling turns RF on and off dynamically within packet TX and RX.nBluetooth-specified low-power connection mode. While in these low-power connection modes, the CYBLE-473148-01 runs on theLow Power Oscillator and wakes up after a predefined time period.The CYBLE-473148-01 automatically adjusts its power dissipation based on user activity. It supports the following power modes:nActive modenIdle modenSleep mode (not enabled for the specific application the CYBLE-473148-01 is used in)nHIDOFF (deep sleep) mode The CYBLE-473148-01 transitions to the next lower state after a programmable period of user inactivity. When user activityresumes, the CYBLE-473148-01 immediately enters Active mode.In HIDOFF mode, the CYBLE-473148-01 baseband and core are powered off by disabling power to VDDC_OUT and PAVDD. TheVDDO domain remains powered up and will turn the remainder of the chip on when it detects user events. This mode minimizes chippower consumption and is used for extended periods of inactivity.

The microprocessor also includes 2 MB of ROM memory for program storage and 512 KB of RAM for data scratch-pad.The internal ROM provides flexibility during power-on reset to enable the same device to be used in various configurations. Atpower-up, the lower layer protocol stack is executed from the internal ROM.External patches can be applied to the ROM-based firmware to provide flexibility for bug fixes and features additions. The devicealso supports the integration of user applications and profiles. Patches and applications can be stored in on-chip flash.Floating Point UnitThe CYBLE-473148-01 includes the CM4 single precision IEEE-754 compliant floating point unit. For additional details, see the Cor-tex-M4 manual.On-Chip FlashThe silicon device used in the CYBLE-473148-01 module includes 1 MB of on-chip flash. This flash can be used for direct programexecution or for non-volatile data. Typical usage for the on-chip flash includes:nChip configurationnPatchesnPeer addresses and link keysnApplication codenApplication non-volatile datanProduct informationOTPThe CYBLE-473148-01 includes 2 KB of one-time programmable (OTP) memory. This memory can be used by the factory to storeproduct specific information. Note: Use of OTP requires a 3 V supply to be present at all times.External ResetAn external active-low reset signal, XRES, can be used to put the CYBLE-473148-01 in the reset state. An external voltage detectorreset IC with 50 ms delay is needed on the XRES. The XRES should be released only after the VDDO supply voltage level has beenstabilized for 50 ms.

Reset TimingIntegrated Radio TransceiverThe CYBLE-473148-01 has an integrated radio transceiver that is optimized for 2.4 GHz Bluetooth wireless systems. It has beendesigned to provide low power, low cost, and robust communications for applications operating in the globally available 2.4 GHz unli-censed ISM band. It is fully compliant with Bluetooth Radio Specification 3.0 and meets or exceeds the requirements to provide thehighest communication link quality of service.Transmitter PathThe CYBLE-473148-01 features a fully integrated transmitter. The baseband transmit data is GFSK modulated in the 2.4 GHz ISMband.Digital ModulatorThe digital modulator performs the data modulation and filtering required for the GFSK signal. The fully digital modulator minimizesany frequency drift or anomalies in the modulation characteristics of the transmitted signal.Power AmplifierThe CYBLE-473148-01 has an integrated power amplifier (PA) on the silicon device as well as a high power external power amplifier(PA) integrated on the module. The total output power that this module is designed to achieve is +8 dBm.Receiver PathThe receiver path uses a low IF scheme to down convert the received signal for demodulation in the digital demodulator and bit syn-chronizer. The receiver path provides a high degree of linearity, and an extended dynamic range to ensure reliable operation in thenoisy 2.4 GHz ISM band. The front-end topology, which has built-in out-of-band attenuation, enables the CYBLE-473148-01 to beused in most applications without off-chip filtering.Digital Demodulator and Bit SynchronizerThe digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency tracking and bit syn-chronization algorithm.Receiver Signal Strength IndicatorThe radio portion of the CYBLE-473148-01 provides a receiver signal strength indicator (RSSI) to the baseband. This enables thecontroller to take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determinewhether the transmitter should increase or decrease its output power.
Document Number: 002-23505 Rev. ** Page 15 of 34CYBLE-473148-01CalibrationThe CYBLE-473148-01 radio transceiver features a self-contained automated calibration scheme. No user interaction is requiredduring normal operation or during manufacturing to provide optimal performance. Calibration compensates for filter, matching net-work, and amplifier gain and phase characteristics to yield radio performance within 2% of what is optimal. Calibration takes processand temperature variations into account, and it takes place transparently during normal operation and hop setting times.Internal LDO RegulatorThe CYBLE-473148-01 has an integrated 1.2 V LDO regulator that provides power to the digital and RF circuits. The 1.2V LDO reg-ulator operates from a 1.425 V to 3.63 V input supply with a 30 mA maximum load current.Peripheral Transport UnitUART InterfaceThe CYBLE-473148-01 includes a UART interface for factory programming as well as when operating as a BT HCI device in a sys-tem with an external host. The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, and CTS) with adjustable baudrates from 9600 bps to 6 Mbps. During initial boot, UART speeds may be limited to 750 kbps. The baud rate may be selected via avendor-specific UART HCI command. The CYBLE-473148-01 has a 1040-byte receive FIFO and a 1040-byte transmit FIFO to sup-port enhanced data rates. The interface supports the Bluetooth UART HCI (H4) specification. The default baud rate for H4 is 115.2kbaud.The UART clock default setting is 24 MHz. The baud rate of the CYBLE-473148-01 UART is controlled by two values. The first is aUART clock divisor (set in the DLBR register) that divides the UART clock by an integer multiple of 16. The second is a baud rateadjustment (set in the DHBR register) that is used to specify a number of UART clock cycles to stuff in the first or second half of eachbit time. Up to eight UART cycles can be inserted into the first half of each bit time, and up to eight UART clock cycles can beinserted into the end of each bit time. Table 6 contains example values to generate common baud rates with a 24 MHz UART clock.Tab le 7 contains example values to generate common baud rates with a 48 MHz UART clock.Table 6.

Document Number: 002-23505 Rev. ** Page 16 of 34CYBLE-473148-01Support for changing the baud rate during normal HCI UART operation is included through a vendor-specific command that allowsthe host to adjust the contents of the baud rate registers.The CYBLE-473148-01 UART operates correctly with the host UART as long as the combined baud rate error of the two devices iswithin ±5%.Peripheral UART InterfaceThe CYBLE-473148-01 has a second UART that may be used to interface to peripherals. This peripheral UART is accessed throughthe optional I/O ports, which can be configured individually and separately for each functional pin. ADC PortThe ADC block is a single switched-cap Σ-Δ ADC core for audio and DC measurement. It operates at the 12 MHz clock rate. Theinternal bandgap reference has ±5% accuracy without calibration.

Document Number: 002-23505 Rev. ** Page 5 of 34CYBLE-473148-01Pad Connection InterfaceAs shown in the bottom view of Figure 2 on page 4, the CYBLE-473148-01 has seven main connections that are connected to thehost board via castellated solder pads (“CSP”). The CYBLE-473148-01 also includes additional solder pad connections (“SP”) usedfor debug or testing on the bottom side of the module. Table 2 and Figure 3 detail the solder pad length, width, and pitch dimensionsof the CYBLE-473148-01 module. Figure 3. Solder Pad Dimensions (Seen from Bottom)To maximize RF performance, the host layout should follow these recommendations:1. Antenna Area Keepout: The host board directly below the antenna area of the Cypress module (see Figure 2 on page 4) mustcontain no ground or signal traces. This keep out area requirement applies to all layers of the host board. 2. Module Placement: The ideal placement of the Cypress Bluetooth module is in a corner of the host board with the PCB traceantenna located at the far corner. This placement minimizes the additional recommended keep out area stated in item 2. Pleaserefer to AN96841 for module placement best practices.3. Optional Keepout: To maximize RF performance, the area immediately around the Cypress Bluetooth module PCB trace antennamay contain an additional keep out area, where no grounding or signal traces are contained. The keep out area applies to all layersof the host board. The recommended dimensions of the host PCB keep out area are shown in Figure 4 (dimensions are in mm).Figure 4.

Table 3 lists the solder pads onthe CYBLE-473148-01, the silicon device pin, and denotes what functions are available for each solder pad. Table 3 also lists theprimary/intended function for each solder pad for the application this module was specifically designed for.Connections and Optional External ComponentsPower Connections (VDD)The CYBLE-473148-01 contains one power supply connection, VDD.VDD accepts a supply input of 3.30 V. Table 9 provides this specification. The maximum power supply ripple for this power connectionis 300 mV, as shown in Table 9. Considerations and Optional Components for Brown Out (BO)ConditionsPower supply design must be completed to ensure that the CYBLE-473148-01 module does not encounter a Brown Out condition,which can lead to unexpected funcitonality, or module lock up. A Brown Out condition may be met if power supply provided to themodule during power up or reset is in the range shown below: VIL ≤ VDD ≤ VIHRefer to Table 13 for the VIL and VIH specifications. System design should ensure that the condition above is not encountered when power is removed from the system. In the event thatthis cannot be guaranteed (i.e. battery installation, high value power capacitors with slow discharge), it is recommended that anexternal voltage detection device be used to prevent the Brown Out voltage range from occuring during power removal. Please referto Figure 7 for the recommended circuit design when using an external voltage detection IC.Table 3.

Document Number: 002-23505 Rev. ** Page 8 of 34CYBLE-473148-01Figure 7. Reference Circuit Block Diagram for External Voltage Detection ICIn the event that the module does encounter a Brown Out condition, and is operating erratically or not responsive, power cycling themodule will correct this issue and once reset, the module should operate correctly. Brown Out conditions can potential cause issuesthat cannot be corrected, but in general, a power-on-reset operation will correct a Brown Out condition. External Reset (XRES)The CYBLE-473148-01 has an integrated power-on reset circuit which completely resets all circuits to a known power on state. Thisaction can also be envoked by an external reset signal, forcing it into a power-on reset state. The XRES signal is an active-low signal,which is an input to the CYBLE-473148-01 module (solder pad 3). The CYBLE-473148-01 module does not require an external pull-upresistor on the XRES input During power on operation, the XRES connection to the CYBLE-473148-01 is required to be held low 50 ms after the VDD powersupply input to the module is stable. This can be accomplished in the following ways: nThe host device should connect a GPIO to the XRES of Cypress CYBLE-473148-01 module and pull XRES low until VDD is stable.XRES is recommended to be released 50 ms after VDD is stable.nIf the XRES connection of the CYBLE-473148-01 module is not used in the application, a 0.33 uF capacitor may be connected tothe XRES solder pad of the CYBLE-473148-01 in order to delay the XRES release. The capacitor value for this recommendedimplementation is approximate, and the exact value may differ depending on the VDD power supply ramp time of the system. Thecapacitor value should result in an XRES release timing of 50 ms after VDD stability. nThe XRES release timing may be controlled by a external voltage detection IC. XRES should be released 50 ms after VDD is stable.Refer to Figure 10 on page 14 for XRES operating and timing requirements during power on events.UART ConnectionsFor full UART functionality, all UART signals must be connected to the Host device. If full UART functionality is not being used, andonly UART RXD and TXD are desired or capable, then the following connection considerations should be followed for UART RTS andCTS: nUART RTS: Can be left floating, pulled low, or pulled high. RTS is not critical for initial firmware uploading at power on. nUART CTS: Must by pulled low to bypass flow control and to ensure that continuous data transfers are made from the host to themodule. External Component RecommendationPower Supply CircuitryIt is not required to place any power supply decoupling or noise reduction circuitry on the host PCB. If desired, an external ferrite beadbetween the supply and the module connection can be included, but is not necessary. If used, the ferrite bead should be positionedas close as possible to the module pin connection. If used, the recommended ferrite bead value is 330 Ω, 100 MHz.

Document Number: 002-23505 Rev. ** Page 12 of 34CYBLE-473148-01Power Management UnitThe Power Management Unit (PMU) provides power management features that can be invoked through power management registersor packet handling in the baseband core. This section contains descriptions of the PMU features.Figure 9. Power Management Unit of CYW20719RF Power ManagementFigure 9 shows the CYBLE-473148-01 power management unit (PMU) block diagram that is contained in the CYW20719 silicondevice. The CYW20719 includes an integrated buck regulator, a bypass LDO, a capless LDO, and an additional 1.2 V LDO for RF.Host Controller Power ManagementPower is automatically managed by the firmware based on input device activity. As a power-saving task, the firmware controls thedisabling of the on-chip regulator when in HIDOFF (deep sleep) mode.BBC Power ManagementThere are several low-power operations for the BBC:nPhysical layer packet handling turns RF on and off dynamically within packet TX and RX.nBluetooth-specified low-power connection mode. While in these low-power connection modes, the CYBLE-473148-01 runs on theLow Power Oscillator and wakes up after a predefined time period.The CYBLE-473148-01 automatically adjusts its power dissipation based on user activity. It supports the following power modes:nActive modenIdle modenSleep mode (not enabled for the specific application the CYBLE-473148-01 is used in)nHIDOFF (deep sleep) mode The CYBLE-473148-01 transitions to the next lower state after a programmable period of user inactivity. When user activityresumes, the CYBLE-473148-01 immediately enters Active mode.In HIDOFF mode, the CYBLE-473148-01 baseband and core are powered off by disabling power to VDDC_OUT and PAVDD. TheVDDO domain remains powered up and will turn the remainder of the chip on when it detects user events. This mode minimizes chippower consumption and is used for extended periods of inactivity.
Document Number: 002-23505 Rev. ** Page 13 of 34CYBLE-473148-01Microprocessor UnitThe CYBLE-473148-01 microprocessor unit runs software from the link control (LC) layer up to the host controller interface (HCI).The microprocessor is a Cortex®-M4 32-bit RISC processor with embedded ICE-RT debug and serial wire debug (SWD) interfaceunits. The microprocessor also includes 2 MB of ROM memory for program storage and 512 KB of RAM for data scratch-pad.The internal ROM provides flexibility during power-on reset to enable the same device to be used in various configurations. Atpower-up, the lower layer protocol stack is executed from the internal ROM.External patches can be applied to the ROM-based firmware to provide flexibility for bug fixes and features additions. The devicealso supports the integration of user applications and profiles. Patches and applications can be stored in on-chip flash.Floating Point UnitThe CYBLE-473148-01 includes the CM4 single precision IEEE-754 compliant floating point unit. For additional details, see the Cor-tex-M4 manual.On-Chip FlashThe silicon device used in the CYBLE-473148-01 module includes 1 MB of on-chip flash. This flash can be used for direct programexecution or for non-volatile data. Typical usage for the on-chip flash includes:nChip configurationnPatchesnPeer addresses and link keysnApplication codenApplication non-volatile datanProduct informationOTPThe CYBLE-473148-01 includes 2 KB of one-time programmable (OTP) memory. This memory can be used by the factory to storeproduct specific information. Note: Use of OTP requires a 3 V supply to be present at all times.External ResetAn external active-low reset signal, XRES, can be used to put the CYBLE-473148-01 in the reset state. An external voltage detectorreset IC with 50 ms delay is needed on the XRES. The XRES should be released only after the VDDO supply voltage level has beenstabilized for 50 ms.
Document Number: 002-23505 Rev. ** Page 14 of 34CYBLE-473148-01Figure 10. Reset TimingIntegrated Radio TransceiverThe CYBLE-473148-01 has an integrated radio transceiver that is optimized for 2.4 GHz Bluetooth wireless systems. It has beendesigned to provide low power, low cost, and robust communications for applications operating in the globally available 2.4 GHz unli-censed ISM band. It is fully compliant with Bluetooth Radio Specification 3.0 and meets or exceeds the requirements to provide thehighest communication link quality of service.Transmitter PathThe CYBLE-473148-01 features a fully integrated transmitter. The baseband transmit data is GFSK modulated in the 2.4 GHz ISMband.Digital ModulatorThe digital modulator performs the data modulation and filtering required for the GFSK signal. The fully digital modulator minimizesany frequency drift or anomalies in the modulation characteristics of the transmitted signal.Power AmplifierThe CYBLE-473148-01 has an integrated power amplifier (PA) on the silicon device as well as a high power external power amplifier(PA) integrated on the module. The total output power that this module is designed to achieve is +8 dBm.Receiver PathThe receiver path uses a low IF scheme to down convert the received signal for demodulation in the digital demodulator and bit syn-chronizer. The receiver path provides a high degree of linearity, and an extended dynamic range to ensure reliable operation in thenoisy 2.4 GHz ISM band. The front-end topology, which has built-in out-of-band attenuation, enables the CYBLE-473148-01 to beused in most applications without off-chip filtering.Digital Demodulator and Bit SynchronizerThe digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency tracking and bit syn-chronization algorithm.Receiver Signal Strength IndicatorThe radio portion of the CYBLE-473148-01 provides a receiver signal strength indicator (RSSI) to the baseband. This enables thecontroller to take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determinewhether the transmitter should increase or decrease its output power.
Document Number: 002-23505 Rev. ** Page 15 of 34CYBLE-473148-01CalibrationThe CYBLE-473148-01 radio transceiver features a self-contained automated calibration scheme. No user interaction is requiredduring normal operation or during manufacturing to provide optimal performance. Calibration compensates for filter, matching net-work, and amplifier gain and phase characteristics to yield radio performance within 2% of what is optimal. Calibration takes processand temperature variations into account, and it takes place transparently during normal operation and hop setting times.Internal LDO RegulatorThe CYBLE-473148-01 has an integrated 1.2 V LDO regulator that provides power to the digital and RF circuits. The 1.2V LDO reg-ulator operates from a 1.425 V to 3.63 V input supply with a 30 mA maximum load current.Peripheral Transport UnitUART InterfaceThe CYBLE-473148-01 includes a UART interface for factory programming as well as when operating as a BT HCI device in a sys-tem with an external host. The UART physical interface is a standard, 4-wire interface (RX, TX, RTS, and CTS) with adjustable baudrates from 9600 bps to 6 Mbps. During initial boot, UART speeds may be limited to 750 kbps. The baud rate may be selected via avendor-specific UART HCI command. The CYBLE-473148-01 has a 1040-byte receive FIFO and a 1040-byte transmit FIFO to sup-port enhanced data rates. The interface supports the Bluetooth UART HCI (H4) specification. The default baud rate for H4 is 115.2kbaud.The UART clock default setting is 24 MHz. The baud rate of the CYBLE-473148-01 UART is controlled by two values. The first is aUART clock divisor (set in the DLBR register) that divides the UART clock by an integer multiple of 16. The second is a baud rateadjustment (set in the DHBR register) that is used to specify a number of UART clock cycles to stuff in the first or second half of eachbit time. Up to eight UART cycles can be inserted into the first half of each bit time, and up to eight UART clock cycles can beinserted into the end of each bit time.
