Only the WLAN Core is enabled; the Bluetooth and FM cores are disabled. Figure 3 TiWi-BLECA Power-up Sequence Requirements 1. No signals are allowed on the IO pins if no IO power is supplied, because the IOs are not 'failsafe’. Exceptions are CLK_REQ_OUT, SLOWCLK, XTALP, and AUD_xxx, which are failsafe and can tolerate external voltages with no VDDS and DC2DC". 2. VBAT, VIO, and SLOWCLK must be available before WL_EN. 3. Twakeup = T1 + T2 The duration of T1 is defined as the time from WL_EN=high until Fref is valid for the SoC. T1=~55ms The duration of T2 depends on: Operating system – Host enumeration for the SDIO/WSPI – PLL configuration – Firmware download – Releasing the core from reset – Firmware initialization

TiWi-BLECA TRANSCEIVER MODULE USER MANUAL The information in this document is subject to change without notice. TiWi-BLECA Copyright © 2013 LS Research, LLC Page 19 of 32 ENABLE SCHEME The module has 3 enable pins, one for each core: WL_EN, and BT_EN and FM_EN. Presently, there are 2 modes of active operation now supported: WLAN and Bluetooth. It is recommended that the FM_EN pin be grounded to disable the FM section. It is also recommended that the FM section be disabled by Bluetooth HCI commands. 1. Each core is operated independently by asserting each EN signal to Logic '1'. In this mode it is possible to control each core asynchronously and independently. 2. Bluetooth mode operation. WLAN will be operated through WL_EN asynchronously and independently of Bluetooth. IRQ OPERATION 1. The default state of the WLAN_IRQ prior to firmware initialization is 0. 2. During firmware initialization, the WLAN_IRQ is configured by the SDIO module; a WLAN_IRQ changes its state to 1. 3. A WLAN firmware interrupt is handled as follows: a. The WLAN firmware creates an Interrupt-to-Host, indicated by a 1-to-0 transition on the WLAN_IRQ line (host must be configured as active-low or falling-edge detect). b. After the host is available, depending on the interrupt priority and other host tasks, it masks the firmware interrupt. The WLAN_IRQ line returns to 1 (0-to-1 transition on the WLAN_IRQ line). c. The host reads the internal register status to determine the interrupt sources - the register is cleared after the read. d. The host processes in sequence all the interrupts read from this register e. The host unmasks the firmware interrupts. 4. The host is ready to receive another interrupt from the WLAN device.

TiWi-BLECA TRANSCEIVER MODULE USER MANUAL The information in this document is subject to change without notice. TiWi-BLECA Copyright © 2013 LS Research, LLC Page 26 of 32 CLEANING In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed with any cleaning process.  Cleaning with water can lead to capillary effects where water is absorbed into the gap between the host board and the module. The combination of soldering flux residuals and encapsulated water could lead to short circuits between neighboring pads. Water could also damage any stickers or labels.  Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the RF shield, which is not accessible for post-washing inspection. The solvent could also damage any stickers or labels.  Ultrasonic cleaning could damage the module permanently. OPTICAL INSPECTION After soldering the Module to the host board, consider optical inspection to check the following:  Proper alignment and centering of the module over the pads.  Proper solder joints on all pads.  Excessive solder or contacts to neighboring pads, or vias. REWORK The module can be unsoldered from the host board if the Moisture Sensitivity Level (MSL) requirements are met as described in this datasheet. Never attempt a rework on the module itself, e.g. replacing individual components. Such actions will terminate warranty coverage. SHIPPING, HANDLING, AND STORAGE Shipping Bulk orders of the TiWi-BLECA modules are delivered in trays of 100 or reels of 1,000. Handling The TiWi-BLECA modules contain a highly sensitive electronic circuitry. Handling without proper ESD protection may destroy or damage the module permanently.
