12 4 M1-Mini Overview M1-Mini is the smallest multi-protocol radio frequency identification (RFID) read/write radio module in the market, complete with internal antenna. The M1-Mini is a multi-protocol RFID read/write module for use with most industry standard 13.56 megahertz (MHz) RFID tags and smart labels. The extremely low-profile and low-power consumption of the M1-Mini makes it the ideal candidate for spatially constrained, power-sensitive applications. An internal LDO regulator provides a low-noise 3V system voltage. The M1-Mini offers multiple antenna options including an onboard antenna, the ability to connect a custom external antenna, and the ability to utilize both the internal and external antennas together (though utilizing dual antenna configuration requires advanced RF knowledge).

16 7 Environmental Specifications 7.1 Electrostatic Precautions CAUTION – Failure to take proper electrostatic precautions may result in damage to or failure of your M1-Mini. The M1-Mini contains static-sensitive parts. Observe the following precautions to prevent damage to these parts. • Wear a static grounding strap when handling electronic control components • Keep all plastic, vinyl, and Styrofoam (except antistatic versions) away from printed circuit boards. • Do not touch the components or conductors on a printed circuit board with your hands or with conductive devices. 7.2 Temperature Ratings Stresses beyond these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These maximum stress ratings do not imply maximum operating conditions. Table 7-1: Temperature Ratings Specification Rating Temperature range Temperature is 25 degrees Celsius unless otherwise noted Operating -10 to +70 degrees C Storage -20 to +85 degrees C
17 8 Electrical Specifications This chapter discusses the electrical specifications of the M1-Mini. Unless otherwise noted, the following assumptions apply to these specifications: • Temperature is 25 degrees Celsius. • Frequency is 13.56 MHz. Table 8-1: Electrical Specifications Specification Min Typ Max Units/Notes RF Characteristics Frequency (Direct output) 13.56 MHz Transmission Parameters Output Power 13.0 16.0 18.0 dBm Optimum PA Load Impedance 50 Ohms Logic Inputs High state input voltage 2.4 V Low state input voltage 0.45 V Input Current (IINH/IINL) ± 20 mA Logic Outputs Output High Voltage (VOH) 2.3 3 V Output Low Voltage (VOL) 0 0.6 V Output Current (IINH/IINL) ± 20 mA Power Supply VIN Input Voltage Range 3.2 10 V Power Supply Current consumption at 5V Active (scanning) 60 mA Idle 15 mA Sleep 60 uA
18 8.1 Absolute Maximum Ratings Stresses beyond these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These maximum stress ratings do not imply maximum operating conditions. Table 8-2: Maximum Voltage Ratings Specification Rating Maximum power supply voltage 10 V Digital I/O voltage to GND -0.3 to 3.3V
19 8.2 Power Supply Options The power supply options for the M1-Mini are described in this section. The figure below shows an example the standard power configuration. Figure 4: M1-Mini Powered at VIN ≤ 5V The M1-mini uses an on-board linear voltage regulator (LDO) that generates VOUT = 3.0V at pin 14, from supply-voltage input to pin 12 within 3.2V ≤ VIN ≤ 6.0V.
20 9 Host Interface Specifications The M1-Mini is supplied with TTL serial as the standard host interface. SPI and I2C host interface types are available with separate firmware. 9.1 TTL Serial TTL signal levels of 0 to 3V are used to interface the M1-Mini to a host device. A three-wire serial connection is provided. The M1-Mini does not support RTS and CTS handshaking signals therefore Hardware Flow Control is not available. Figure 5: TTL Connection: M1-Mini to Host • In addition to the signal connections, the host must supply input voltage. • The serial baud rate of the M1-Mini is software selectable. The following table shows the selectable Baud rates. 4800 bits/sec N,8,1 +/- 0.3% error 9600 bits/sec N,8,1 +/- 0.3% error 19200 bits/sec N,8,1 +/- 0.3% error 38400 bits/sec N,8,1 +/- 0.3% error 57600 bits/sec N,8,1 +/- 1.9% error NOTE – N,8,1 means No Parity Bit, 8 Data Bits, 1 Stop Bit.
21 9.2 SPI The M1-Mini allows the use of a standard Serial Peripheral Interface (SPI) for connecting to a host controller. The M1-Mini must have the proper firmware to enable SPI operation. The M1-Mini operates as an SPI slave device; the clock is always controlled by the host system. The SPI interface uses three wires: SCK, SDI, and SDO. SDO is the serial data out (from the M1-Mini to the host system). SDI is the serial data in (to the M1-Mini from the host system). SCK is the serial clock (controlled by the host system). The M1-Mini is set so that data is latched into and sent on the positive edge of the SCK signal. Data is sent from the M1-Mini on the SDO signal at the same time that it is received by the M1-Mini on the SDI signal. The data is sent and received MSB first. Data exchange between the host and the M1-Mini is defined according to the SkyeTek Protocol, Binary mode. NOTE – Loop and Inventory modes are not supported for the SPI host interface. Figure 6: SPI Connection: M1-Mini to Host • In addition to the signal connections, the host must supply input voltage. • Care should be taken to minimize signal length between the host and the module.
22 Figure 7: Details of the SPI Communication Link • Idle clock should be held low • Data is transitioned on the rising edge of the clock • Data is latched on the falling edge of the clock • Data is sent and received MSB first • The maximum clock rate is 3 MHz. Care should be taken to minimize the distance between M1-Mini and host. • Host should wait at least 100us between each byte • Host should wait for the M1-Mini to finish executing the command before clocking the response • Commands should be sent to the M1-Mini at least 10ms apart
23 9.3 I2C The M1-Mini supports standard I2C for connecting to a host controller. The M1-Mini operates as an I2C slave device. Standard 2-wire connection is used with SCL and SDA. SCL is the bi-directional system clock line. SDA is the bi-directional serial data line. The M1-Mini must have proper firmware to enable I2C operation. I2C fast mode is supported to provide a 400 kHz data rate or the slower 100 kHz data rate. The data is sent and received MSB first. Data exchange between the host and the M1-Mini is defined according to the SkyeTek Protocol, Binary mode. NOTE – Loop and Inventory modes are not supported for the I2C Host Interface. Figure 8: I2C Connection: M1-Mini to Host • Both 100kHz and fast mode 400kHz clock rates are supported • External pull up resistors are required but should be strong (less than or equal to 2.2kΩ) for fast mode to function properly • I2C address should be 0x3F; 7-bit address mode should be used • Write should be used for the request • Read should be used for the response • A delay must be included between the request and response for tag commands to function properly • Be sure to read at least enough bytes to receive the entire response, including CRC, for each response sequence or future responses from the module may give unexpected results

26 11 Antenna Options 11.1 Read Range In general, read range depends on the RFID Transponder’s IC and antenna, and the RFID reader and reader antenna, in addition to the environment in which the system is implemented. The M1-Mini has a read/write distance that is typically greater than or equal to 50.8 mm (2 inch) for a Texas Instruments Tag-It HF-I (ISO15693) RFID inlay with antenna dimensions 22.5 mm x 38 mm (TI p/n RI-I03-112A) 11.2 Antenna Configurations By default the internal antenna of the M1-Mini is connected during production. In the event that the user wants to connect an external antenna between the INT and ANT pins of the M1-Mini, refer to Table 14-1. Figure 9: M1-Mini internal antenna schematic Table 11-1: M1-Mini Internal Antenna Configuration Details Internal Ant Active? Custom External Antenna? Remove Populate N Y Cseries - Y N Cseries NOTE – Place custom antenna between pin 2 (ANT) and pin 1 (GND). Refer to AN001 for more information on how to make your own custom antenna. The default M1-Mini configuration: • Rseries = shorted (connects the transmit and the receive path together) • Cseries = 220pF (This is essentially used to match the internal antenna to the output of the transceiver IC) • Cparallel = 2000pf (This is the tuning cap value for the internal antenna) • Rdamp = unpopulated (Rdamp can be used to change the Q of the antenna circuit)

30 13 Customizing System Parameters System parameters let you configure reader settings to customize the reader for your environment. All parameters can be changed in both volatile and non-volatile memory. When changing a parameter in volatile memory the change in the parameter is realized immediately, but is reset upon power-cycling the M1-Mini. Alternatively, when changing a parameter in non-volatile memory the change in the parameter is not realized immediately, but will only be realized after power-cycling the M1-Mini. The following table summarizes the parameters for the M1-Mini. Name Parameter Address Request Blocks Length (bytes) Parameter Values Factory Default Parameter Value Specifies READ WRITE SERIAL NUMBER 0x00 2 4 0x00000000- 0xFFFFFFFF custom serial number custom no FIRMWARE VERSION 0x01 1 2 0x0000-0xFFFF depends on release firmware version yes no READER ID (RID) 0x02 1 1 0x00-0xFF 0xFF (“no RID”) reader network ID yes yes BAUD RATE 0x03 1 1 0xFF 0x00 0x01 0x02 0x03 0x04-0xFE 0x00 4800 9600 19200 38400 57600 reserved no yes SLEEP MODE 0x04 1 1 0x00 0x01-0xFF not applicable sleep active no yes Reserved 0x05 None no no Reserved 0x06 None no no USER PORT DIRECTION 0x07 1 1 0x00 defines pins as inputs or outputs yes yes USER PORT VALUE 0x08 1 1 0x00 writes values of output pins reads values of input pins yes yes Reserved 0x09–0x11 None no no STARTUP COMMAND 0x12 1 1 see detailed description 0x00 see notes no yes Reserved 0x13–0x80 None no no Table 13-1: M1-Mini System Parameters
31 13.1 Changing System Parameters CAUTION – Changing system parameter values – especially the default values – can render your M1-Mini non-operational in your environment. Research, record, and test all planned changes to make sure they are compatible with your system. You can read or write system parameters via the following commands: • Read System Parameter (0x22) – Reads the current value of the system parameter at the memory address specified. • Write System Parameter (0x42) – Writes a new value to the system parameter at the memory address specified. • Read Memory (0x21) – Reads the system parameter value at the address specified out of non-volatile memory. • Write Memory (0x41) - Writes a new system parameter value to the non-volatile memory. This saves the setting even after a power cycle or reset. See System Parameter Descriptions in section 13.2 for detailed information about individual parameters. Also, see the SkyeTek Protocol v2 Guide for a full description of the system parameter commands. CAUTION – Resetting (or cycling power) on your M1-Mini causes all system parameters to revert to their default values. Any changes made to system parameters in RAM are lost at reset unless you write them to the non-volatile memory as the new default values. Any changes to the default values do not take effect until the reader is reset.
32 13.2 System Parameter Descriptions This section describes the M1-Mini system parameters in detail. 13.2.1 Serial Number The Serial Number system parameter is a read only parameter set at manufacture time. It is not a unique number for each module. It can be set to a specific value upon request. By default, it is set to 0x00000000. 13.2.2 Firmware Version The Firmware Version system parameter is a read-only parameter that contains a two-byte firmware version number. The firmware version number is read with a Read System command. 13.2.3 Reader ID The Reader ID system parameter is a read/write system parameter that contains a one-byte Reader ID value. The Reader ID can be changed in both volatile memory (Write System command) and nonvolatile memory (Write Memory command). The Reader ID can be read out of either volatile (Read System command) or non-volatile memory (Read Memory command). All non-volatile writes have to be followed by a power cycle before the settings take effect. Reader ID values can take on any value from 0x00-0xFF. 0xFF is the default and the reader responds to commands sent to it not containing the Reader ID. From this point forward examples some examples are in ASCII mode and some are in binary mode. 13.2.4 Baud Rate The Baud Rate system parameter controls the baud rate for serial data communication. The TTL serial interface. The following table contains the possible values for the data field. Baud Rate Data Field 4800 0xFF 9600 0x00 19200 0x01 38400 0x02 57600 0x03 Table 13-2: Baud Rate Parameter Settings 13.2.5 Sleep Mode The reader can be set to a low power sleep mode through software using this system parameter. Sleep mode is activated by setting this system parameter to 0x00. Sleep is explained in detail in the Operating Modes section of the document, specifically section 14.1.
33 13.2.6 Startup Command The Startup Command system parameter allows the user to set any command to run at module power up. This command can be very useful in battery powered or otherwise power sensitive applications as it minimizes runtime. The full functionality of this system parameter including examples is explained in detail in the Operating Modes section of the document, specifically section 0.
34 14 Operating Modes The M1-Mini has three operating modes: Sleep, Active, and Loop. Active is the normal mode of operation. The following sections explain the Sleep and Loop modes as well as how to set a specific command to run on startup using the Startup Command system parameter. 14.1 Sleep Mode The low-power Sleep mode can be used to conserve battery or system power. The reader can be put into Sleep mode by writing the Data 0x00 to the Sleep Mode system parameter using the Write System command. After the reader gives a positive response, it enters Sleep mode. Any command wakes the reader from Sleep mode. Even sending a single byte to the reader wakes it from Sleep mode. The reader gives the same positive response upon waking from Sleep mode as it gives upon entering Sleep mode. 14.1.1 Write System Parameter – Sleep Mode Example (ASCII) The following request puts the reader into Sleep mode if it is in active mode, and brings it out of Sleep mode if the reader is already in Sleep mode. Flag Command Starting Block Number of Blocks Data CRC Request <CR> 20 42 04 01 00 35E9 <CR> Response CRC Response <LF> 42 6116 <CR><LF> 14.1.2 Write System Parameter – Sleep Mode Example (Binary) The following request puts the reader into Sleep mode if it is in active mode, and brings it out of Sleep mode if the reader is already in sleep mode. Length Flag Command Starting Block Number of Blocks Data CRC Request <STX> 0x07 0x20 0x42 0x04 0x01 0x00 0x35E9 Length Response CRC Response <STX> 0x03 0x42 0x4B7E
35 14.1.3 Write Memory – Sleep Mode Example (Binary) The following request puts the reader into Sleep mode upon power up. This process is done provided that no startup command is stored using the Startup Command system parameter. Flag Command Starting Block Number of Blocks Data Request <CR> 00 41 04 01 00 <CR> Response Response <LF> 41 <CR><LF>
36 14.2 Loop Mode Loop mode allows the user to send a single select tag command to the reader and receive responses from the reader each time a tag is present in the field with no further requests necessary. The loop flag is used in conjunction with the Select Tag command to set the reader into Loop mode. NOTE – Loop Mode is not supported for the SPI or I2C host interface. 14.2.1 Select Tag – Loop Mode Example (ASCII) The following request initiates Loop Mode with Auto-detect selected as the tag type: Flag Command Tag Type Request <CR> 01 14 00 <CR> Response Response <LF> 1C <CR><LF> The response 1C is immediately sent to indicate that the reader has successfully entered loop mode. The following responses will be received when an ISO-15693 tag is introduced into the reader’s field. The responses below show the tag being read three times: Response Tag Type Data (TID) Response <LF> 14 01 E0 07 00 00 01 64 5E 37 <CR><LF> Response <LF> 14 01 E0 07 00 00 01 64 5E 37 <CR><LF> Response <LF> 14 01 E0 07 00 00 01 64 5E 37 <CR><LF>
37 14.2.2 Select Tag – Loop Mode Example (Binary) The following request initiates Loop Mode with Auto-detect selected as the tag type: Length Flag Command Tag Type CRC Request <STX> 0x05 0x21 0x14 0x00 0xC541 Length Response CRC Response <STX> 0x03 0x1C 0xF085 The response 1C is immediately sent to indicate that the reader has successfully entered loop mode. The following responses will be received when an ISO-15693 tag is introduced into the reader’s field. The responses below show the tag being read three times: Length Response Tag Type Data (TID) CRC Response <STX> 0x0C 0x14 0x01 E0 04 01 00 08 AE D8 BD 0xBBF3 Response <STX> 0x0C 0x14 0x01 E0 04 01 00 08 AE D8 BD 0xBBF3 Response <STX> 0x0C 0x14 0x01 E0 04 01 00 08 AE D8 BD 0xBBF3
38 14.3 Startup Command The M1-Mini has a provision to store a single command that is executed upon power up. This command is stored by writing to the Startup Command system parameter using the Write System command. The M1-Mini executes the command upon power up and sends the response in either Binary or ASCII mode depending on the mode in which the command was stored. The entire command must be stored—all the fields relevant to the command must be present. For example if the CRC, TID and/or RID flags are set, then the respective fields must have the correct information. In the case of Binary mode, the message length must also be stored as part of the command. The delimiting characters (<CR> in ASCII mode and <STX> in Binary mode) should not be stored. This system parameter can only be written for the Write System command, so there is no Read System and Write/Read Memory support for this system parameter. If no command needs to be executed upon power up, then a single-byte data value should be written to this system parameter. This process turns off the Start Up command functionality. The single byte can be any value, for example 0x00 – 0xFF. 14.3.1 Write System Parameter – Startup Command Example (ASCII) The following request stores the Select Tag (0x14) command with tag type ISO-15693 (0x01) to be executed upon startup. Since the command is stored in ASCII mode, the response upon power up is sent in ASCII mode. Flag Command Starting Block Number of Blocks Data Request <CR> 00 42 12 01 00 14 01 <CR> Response Response <LF> 42 <CR><LF>
39 14.3.2 Write System Parameter – Startup Command Example (Binary) The following request stores the select tag command (0x14) with the tag type set to Auto-Detect (0x00). The flags field in the command, which is stored, shows that the CRC and the Loop flags are set (0x21). This process causes the reader to go into loop mode upon power up and sends responses in Binary mode along with the CRC. The message length (0x05) is also stored along with the rest of the command because it is part of any command sent in Binary mode. Length Flag Command Starting Block Number of Blocks Data CRC Request <STX> 0x0C 0x20 0x42 0x12 0x01 0x05211400C541 0xD591 Length Response CRC Response <STX> 0x03 0x42 0x4B7E 14.3.3 Write System Parameter – Disable Startup Command Functionality (ASCII) The following request turns off the Start Up command functionality. It is sent in ASCII mode. Flag Command Starting Block Number of Blocks Data Request <CR> 00 42 12 01 00 <CR> Response Response <LF> 42 <CR><LF>
