Chapter 1 Introduction Introduction This chapter provides an overview of the RFID Reader Module. Product specifications are provided in Table A-1 on page A-1. The module is a RFID Reader Engine module that supports EPC Gen2 protocol in the UHF frequency band. There are two versions of the module: • 10 mWatt to 1 Watt US (part No. 21-121559-01) • 10 mWatt to 1 Watt EU (part No. 21-121560-01) The differences between the US and EU module are Pre-PA Saw Filter and PA matching components and OEM F/W settings. The RFID Reader Module is based on the Intel R1000 reference design and has been modified for power efficiency and size. The RFID Reader Module is a RFID Radio Engine which supports ISO 18000-6C and Electronic Product Code (EPC) Gen2 reader applications. RFID Reader Module is intended to enable Mobile Computers and Barcode Scanners to read EPC Gen2 UHF RFID tags. The RFID Reader Module is a very small form-factor RFID Reader engine, that when used with a high performance RFID antenna(s), can be commanded to perform EPC Gen2 RFID Reader operations. This document defines the RFID Reader Module functional characteristics (electrical, mechanical) and provides information required by the system integrators to embed the RFID Reader Module in a variety of systems. A section outlining good design practices is also incorporated to help with the overall integration of the device. The RFID Reader Module supports all EPC Gen2 Link Profiles of the R1000 Reference Design. The RFID Reader Module is a EPC Gen2 Compliant Mono-static Reader Module that operates in the 902MHz-928MHz ISM band in US and Canada, and 865.6MHz - 867.6 MHz in Europe. For details see Technical Specifications on page A-1 The RFID Reader Module reference performance specifications are provided in Appendix A, Technical Specifications on page A-7. 1-2 RFID Reader Module, Integration Guide Sailfish Integration In the early stages of Sailfish integration, the integrators need focus on key design areas to achieve the best RFID reader performance. Some key areas that should be focused on are: 1. The power supply capacity must be sufficient for the power requirements at the targeted RF power levels. Be sure to account for: • Voltage drops from your 5V supply to the Sailfish Module inputs • The 5V supply must stay within the range of 5V +/- 5% at the Sailfish host connector after all of the voltage drops of battery impedances, connector contacts, flex cables, pc traces etc. The max currents of the module are specified at 5.0V. • Sailfish creates very long pulses (up to 400ms) of current peaks. These current surges (that Sailfish requires) must not create a low battery event in the power micro circuit. 2. RFID Antenna • The read performance of the Sailfish Module depends on not only the gain of the antenna but more importantly the Return Loss or VSWR of the antenna across the entire bandwidth of the radio (unlike 802.11 or Bluetooth). The radio must receive a tag response while it is transmitting, and the more signal that is reflected back from the antenna, the more blinded the receiver becomes. Also, RFID tags are not always polarized the same way as the antenna and a robust antenna design could greatly improve read performance. Antenna performance depends on the application requirements but must also meet the requirements stated in Appendix C, Regulatory Requirements. • The antenna features that must be emphasized are bandwidth, return loss, and gain. If the return loss can be optimized over the entire bandwidth of the radio, the radio will accomplish its reading of the tag population in the least amount of time and for the least amount of battery power. • With a Motorola designed application, the Sailfish Module can be used to evaluate the VSWR or return loss characteristic of the embedded antenna system for WinCE products. This application is called RFID Demo and is demonstration software which can exercise the sailfish module for various test purposes. 3. Thermal Management • Since Sailfish has been packaged in a very small form factor, thermal management is critical during the integration phase of this module. The Module has been designed to expose the hottest points of the module to a cold-plate or heat-sink through thermal interface material. Proper heat sinking significantly increases the time that the radio can operate without entering a thermal back-off mode. Once in this mode, the radio continues to operate, but at reduced duty cycle and read rates. • Most applications will use some initial duty-cycle (such as 50%) for power management reasons, however this should be considered on an individual application basis. 4. Flex Cable interface • The host interface is a 16 pin flex. Use heavy traces for the VCC and ground traces and it is recommended that an outer ground plane is used to shield the control signals from system noise and ESD. The flex should be kept as short as possible in order to reduce voltage drops to the module. • Once the module and corresponding host connector have been located, it is important to confirm that the signals have not been crossed at the flex connection. This is a common error and should be considered as part of an required design check. Introduction 1-3 Unpacking the Reader Module Carefully remove all protective material from around the reader and save the shipping container for later use. Verify that all equipment was received: • RFID Reader Module Inspect the equipment for damage. If any equipment is missing or if any equipment is damaged, contact the Motorola Technologies Support Center immediately. See Service Information on page viii for contact information. Note: Observe ESD precautions. Exercise care when handling the module. Use grounding wrist straps and handle in a properly grounded work area. for Figure 1-1 RFID Reader Module Connections and Ports See Table Table 2-1 on page 2-4 for a detailed list of the RFID Reader Module connections. The RFID Reader Module has connections for: • Host Port Interface • External antenna(s) • Thermal Contact Points 1-4 RFID Reader Module, Integration Guide Theory of Operation The RFID Reader Module is a UHF, US (902 – 928MHz) and EU (865.6 – 867.6MHz), RFID reader module. The RFID Reader Module can read and write UHF passive RFID tags complying to EPCglobal Gen2 standard. Commands from the reader are broadcast to the tags on the transmit carrier followed by a CW transmission. Passive tags are powered by reader energy before communication between the reader to the tag starts. After decoding the command data, the tags respond by back scattering with encoded data, modulated on the CW transmission. The RFID Reader Module can be used in mobile devices to provide the capability for reading EPC Gen2 RFID tags in the UHF band. Once commanded, the RFID Reader Module interrogates the intended field and listen for RFID tag backscatter. The RFID Reader Module is a mono-static RFID transceiver module using frequency hopping spread Spectrum (FHSS) in order to interrogate tags. For normal operating modes, there are 50 US channels over the 902 to 928MHz ISM Band, and four European channels in the ETSI(EU) 865.6-867.6MHz band that the radio hops over in order to communicate to the tags. The read range of the radio is highly dependant on both the RFID antenna performance, and RF output power. The RFID Reader Module is designed as an embedded module and is intended to be used as an integral part of an RFID system. • Handheld or portable devices • Printers Block Diagram The RFID Reader Module consists of a UHF transceiver and a processor with interfaces to external antenna(s) and a host system. The RFID Reader Module consists of all of the components necessary to make up an RFID Reader Radio for the 915MHz band. The RFID Transceiver IC (R1000) and the Atmel ARM7 Microprocessor (AT91SAM7S256) make up the major portion of the RFID Reader Radio. In addition, the Power Amplifier (MAAP0007649), RF detectors, and other RF components complete the EPC Gen2 compliant module. There are two oscillators on the RFID Reader Module that are used to create the Local Oscillator, and digital timing clocks for the radio. The 24MHz Oscillator provides a reference clock for both the RF PLL and the RF Transceiver. The 18.432MHz Oscillator provides the primary clock for the Arm Processor including a reference for the processors internal PLL. The Impinj R1000 RFIC (U2) implements a UHF RFID transceiver supporting both 868MHz and 915MHz ISM bands. The chip set uses a "Zero Intermediate Frequency (ZIF), high intercept point I/Q architecture for the radio. The architecture contains low-noise, high IP3 amplifiers, quad up/down converters, frequency synthesizers, low-pass filters, AGC receiver amplifiers, transmit/receive switches, and transmitter power amplifiers. The Radio control and EPC Gen2 link protocol is implemented in firmware and is in the Atmel AT91SAM7S256(U12) Arm processor. Introduction 1-5 Figure 1-2 RFID Reader Module Ports/Connectors and Antenna Locations Receive Path The received signal from the antenna is fed to directional coupler (U3) and is coupled through the reverse path to the receive balun, and also to the reverse power detector (U4). The reverse power detector senses RF energy that is reflected from the antenna and compares it to a threshold each time the transmitter ramps. If the threshold is exceeded, the transmitter is halted and the RF energy is turned off in order to protect the PA during a fault event. The receive balun converts the single ended RF signal to a balanced or differential signal before passing it to the R1000 receive pins for demodulation. Transmit Path The transmit path begins with the internal waveform generator in the R1000 (U2) which is up converted and amplified before leaving the R1000 in a differential/balanced format. The transmit signal is converted to a single ended format and passed through a Surface Acoustic Wave (SAW) band pass filter (FL3), and then amplified by a driver amplifier (U22), and finally a Power Amplifier (U17). The output of the power amplifier feeds the input to a dual directional coupler. The coupler samples the transmitted RF signal using a forward RF power detector (U14). This detector has a calibrated output that the radio uses to automatically level the transmitter output. Once the transmit signal leaves the directional coupler, it is fed to a SPDT RF Switch (U5) that is used to feed one of two identical RF paths. The RF path after the switch passes through a Low Pass Filter (FL1, FL2) and then to the RF connector (J1, J2). Microprocessor Control The RFID Reader Module Atmel processor (AT91SAM7S256, U12) is a memory-integrated microcontroller which contains the RFID radio system firmware. The primary function of the processor is interfacing with the RF ASIC to drive the RFID protocol at the MAC level. The Atmel also controls and regulates additional electronics, such as radio power supplies, final stage signal amplification hardware, and sensors for closed loop functionalities. In addition, this controller executes host layer communications to receive /interpret/respond to commands, up-transfer radio link data, as well as store and adjust to radio parameters. Frequency Generation The Frequency generation on the RFID Reader Module is derived from a 24MHz crystal oscillator (Y1) reference that is used to generate the local oscillator (LO) using the internal PLL of the R1000. This LO is used to both up convert the transmit baseband signal and used to down convert the receive RF signal to baseband for detection. This LO is in the range of 902MHz to 928MHz for the US module and 865.6-867.6 for the EU module. 1-6 RFID Reader Module, Integration Guide Chapter 2 Installation Overview This chapter provides information for configuration, mounting and installing the RFID Reader Module. Physical and electrical considerations are presented, together with recommended window properties and housing designs. Mounting Considerations The RFID reader module housing design must protect the module from impact and adverse environments. The host housing that integrates the RFID Reader Module must be designed so that it can draw the generated heat off the radio and out of the host unit. The module has been designed to be efficient in conducting heat from point of generation to the outside. Thermal slugs are mounted to the board which draw heat from the board to the outside of the EMI shields. This allows the host device to pull the heat off of the module. Additionally, there are two thermally conductive channels on the two side edges of the module which are designed to transfer heat from the module to a thermally conductive bracket. The thermally conductive bracket must be able to dissipate the heat to the outside of the host device. Environment The RFID reader module must be sufficiently enclosed to prevent moisture and/or dust from interfering with the RFID Reader Module operation. Grounding The RFID reader module is grounded through the host interface connector (see Host Interface on page 2-4). ESD Always exercise care when handling the module. Use grounding wrist straps and handle in a properly grounded work area for ESD specifications. 2-2 RFID Reader Module, Integration Guide Location and Positioning The general location and positioning guidelines provided do not consider unique application characteristics. It is recommended that an RFID engineer perform an analysis prior to integration. Using the RFID Reader Module Identify the capabilities scope and the inputs/commands required to access them. Some applications require the RFID Reader Module be mounted to read tags that are automatically presented, or that are presented in a pre-determined location. In these applications RFID reader antenna positioning (with respect to the tag) is critical. Failure to properly position the RFID reader antenna with respect to the tag may lead to degraded or unsatisfactory reading performance. Figure 2-1 Mounting External Hardware Interfaces The RFID Reader Module hardware interface include the input voltage, antenna interface and the host interface. Refer to Appendix A, Technical Specifications for detailed product specifications. Antenna Interface Two bi-directional mono-static antenna ports, user selects transceiver port via host command. U.FL- surface mount coaxial male connector. Antenna diversity is supported on RFID Reader Module. Two antenna connectors allow for the use of horizontal and vertical polarized antennas (optional) in order to achieve optimal read performance for multiple tag orientations. The reference antenna specifications are provided in Table C-1 on page C-4. Installation Thermal Interface Need engineering input for heat dissipation rate.

Best practices indicate that the correct use of this signal is to follow this sequence: Power Off -> Assert TST -> Power On (10 seconds) -> Power Off -> Deassert TST. Because this state is only recoverable by reprogramming the firmware image, strong caution needs be taken to not inadvertently assert this signal. Refer to Atmel AT91SAM7S documentation (e.g Atmel 6175H-ATARM-03-Dec-07) for more in depth documentation on microcontroller function. UART Signals: The module communicates in RS-232 timing and protocol, but single ended 3.3V and 0V referenced to ground. Data rate is 115.2kbaud, 8 data bits, No parity, and one stop bit. UAR-TRX: This is the primary signal for serial communications going to the module. This signal is 3.3V input or 0V input (referenced to ground), and is 5V tolerant. UAR-TTX: This is the primary signal for serial communications coming from the module. This signal is driven actively to 3.3V or 0V referenced level. UAR-TRTS: This signal can be optionally enabled or disabled. This signal is flow control output from the module. This signal is driven actively to 3.3V or 0V referenced to ground. This signal defaults high for those systems that use flow control as DTEs and wired by null modem type configuration. UAR-TCTS: This signal can be enabled or disabled. This signal is flow control input to the module. This signal is 3.3V input or 0V input (referenced to ground), and is 5V tolerant. Note that when the module is actively reading, and CTS is asserted, data will necessarily be buffered. This buffer is finite, and when it runs out of space, the reader will no longer read more tags into the buffer. WAKE/GPIO1: The primary function of this pin is to remove the module from sleep state. Either transition edge (positive or negative) will effect this change. Typical systems will generate a pulse (two successive transitions), the second edge will be ignored. There is a slight power advantage to maintain this signal at a high level (avoids fighting against a pull-up resistor). If a pulse is used to wake the module, its width should be much narrower than the wake time-out interval. The WAKE functionality of this signal is in multiplex with the GPIO1 signal. Care should be taken by the module integrator not to cause contention on this signal (i.e. making GPIO direction output, when WAKE is also actively driven. The Wake timing diagram is provided in Appendix B-1, Timing Requirements for RF Activity. 2-6 RFID Reader Module, Integration Guide Mechanical Characteristics The RFID Reader Module mechanical characteristics include the physical dimensions, the weight and the enclosure, and EMI shielding. Dimensions: 38mm long, by 27mm wide, by 6mm thick. Enclosure and EMI Shielding The RFID Reader Module is shielded on both side using two internal removable EMI shields, one on each side of the board to compartment isolate the RF and digital circuits on the PCB. Each shield consists of a frame soldered to the PCB and a removable cover. Thermal Management A thermally conductive path using copper slugs is provided from the hottest components to the outer surface of the module. The RFID Reader Module should be thermally integrated to allow heat from the micro side of the module to be thermally connected to this outside surface to transfer the heat away from the module. Mounting The RFID Reader Module is intended to be captured along the side edges. The bracket should be designed of a thermally conductive material so that it can transfer heat off the board and into the host system which in turn should be designed to transfer heat out of the host system. The outer 2mm of the module is available for mounting. These surfaces should be used to capture the module in the host product. In addition these surfaces include exposed ground pads, which can be incorporated in the overall thermal management strategy. Installation Note: All dimensions have a 5% tolerthat Figure 2-3 RFID Reader Module Outline Drawing 2-7 2-8 RFID Reader Module, Integration Guide Environmental Characteristics Thermal Management The RFID Reader Module shuts down and turns off should the module temperature exceed 80°C. It turns back on after the module cools off. As the module starts to get hot, the thermal PID (proportional-integral-derivative) controller kicks in. The objective of the PID controller is to keep the unit thermal temperature steady at a set point temperature below the 75°C. The module accomplishes this by over riding the reader duty cycle. When the temperature is below the set point, the PID increases the reader duty cycle close to 100%. When the temperature is above the set point temperature the duty cycle is decreased to allow the unit to cool down. If the module is too hot, read rate may decrease. See Appendix A, Technical Specifications for detailed Temperature, Humidity, ESD, Shock, and Vibration specifications. Read/Write Ranges The reader module has typical read/write range based on a standard configuration. The detailed parameters are provided in Table A-6 on page A-7. These reference values may change depending on tag type, antenna and environmental conditions. The actual range values are also effected by the reflective and absorption properties of the material under the tag.

Expected Read Range* A-8 RFID Reader Module, Integration Guide Link Profiles and XRM The Sailfish module supports all the R1000 Reference Design EPC Gen2 Link Profiles and can be controlled by the host application to use any of the various profiles listed inTable A-7. Several link profiles are selectable through a host application. This allows the reader performance to be tailored for various applications. For example, some link profiles are better suited for close range, high tag populations while others may be better for long range reading of a few tags. Some link profiles use modulation types that are better for power efficiency of the reader in that the power amplifier can be biased more efficiently and others are biased more linear so that the spectrum of the signal is well defined, requiring less bandwidth. In general, the DSB-ASK modulations used in the MRM (multi-reader mode) link profiles have better power efficiency at the expense of a broader spectral mask, while the PR-ASK modulation used by the DRM (Dense Reader Mode) link profile 2 use more power for a given transmit level, but have a tighter spectral mask in order to allow for more readers/less reader to tag interference in a smaller area. The Sailfish Module extended the link profiles in order to take advantage of the tighter spectrum of PR-ASK while allowing for similar power efficiency of the DSB-ASK. This new mode is called XRM and is simply the PR-ASK link profiles, with the lower biasing of the MRM/DSB-ASK modulations. This is not an EPC certified mode, however it reads EPC Gen2 tags and passes the MRM spectral mask and is compliant with all the regulatory requirements. XRM=DRM Modulation at MRM Bias Levels and MRM Spectral Mask (Benefit of DRM Spectrum with Power Requirements of MRM) To illustrate the three different modes, some typical peak current requirements are listed in Table A-7. As shown, DRM requires more current for a given power level. Also, the modulated spectrum of the three most commonly used link profiles are shown in Figure 1. It is evident, that the MRM spectrum is much broader than DRM or XRM and this MRM link profile does not offer any significant performance advantage over XRM. The power requirements for the +27dBm DRM is not significantly less than the current required for the +30dBm MRM and XRM modes, therefore for the same battery power, the user can achieve more read range and better reader density by selecting one of the XRM link profiles. Table A-7 Typical Peak Current for MRM, DRM, XRM for 10dB Return Loss Antenna RF Power Level Setting MRM (LP 1) Peak Current, mA typ DRM (LP 2) Peak Current, mA typ XRM (LP 18) Peak Current, mA typ +30 dBm 1278 N/A 1276 +27dBm 850 1054 852 +24 dBm 784 814 782 Technical Specifications A-9 Figure A-1 DRM, MRM and XRM Transmit Spectrums To summarize, there is little spectral advantage of DRM over XRM and the read rate performance are equivalent since the link parameters are identical. Also, since the XRM power requirements are basically the same as MRM (better power efficiency), the XRM mode should be the preferred mode for most mobile applications. For this reason, the default link is link profile 18. See Table A-8 on page A-10 for the link profile details.

Either transition edge (positive or negative) will effect this transition. The module goes to the Ready State and waits for a command from the host system over the serial port. Typical systems generate a pulse (two successive transitions), the second edge is ignored. There is a slight power advantage to maintain this signal at a high level (avoids fighting against a pull-up resistor). If a pulse is used to wake the module, the width must be narrower than the wake timeout interval. The WAKE functionality of this signal is in multiplex with the GPIO1 signal. The integrator must excercise care not to cause contention on this signal (i.e. making GPIO direction output, when WAKE is also actively driven. *Ready to receive command (CSM:WAIT state). Not an externally visible signal. Figure B-1 RFID Reader Module Wake Signals Timing B-3 TX_MUTE_N This signal provides a hard real-time method to mute the RF output of the module and is useful for rapidly reduceing module current consumption. The PA is shut down directly through hardware. A brief time later, the microcontroller acts on the TXMUTE event by shutting down other radio hardware and returning the module to Ready State. The example (see Figure B-2) shows RF being on prior to assertion of TX_MUTE_N. If Module receives an RF inducing command (e.g. Inventory, Write, etc...) while TX_MUTE_N is already asserted, RF is not generated. In both of these instances a TXMUTE error is generated in "Command End "Packet sent out through the UARTTX signal.
