Indy® RS500 Hardware User’s Guide Revision 0.3, Copyright © 2013, Impinj, Inc. 3 Introduction The Impinj® Indy®RS500 reader is a System-in-Package (SiP) that comprises a completely integrated solution for EPC Gen2 / ISO18000-63 (formerly 18000-6C) applications. The SiP was developed to make embedding UHF RFID reader capability easy. The Indy RS500 builds on market-leading Indy reader chip technology and integrates all of the necessary components into a tiny package. It requires very few external components, is fully tested and is certified for modular operation under FCC and IC regulations. The RS500 comes in a surface mount package designed to work as a SMT (surface mount technology) component in a standard PCB manufacturing process. This document provides instructions to the end-user to ensure optimal performance in their OEM hardware. Details on the use of the Indy®RS500 Development Kit are also included to provide an example of appropriate application.
Indy® RS500 Hardware User’s Guide 4 Revision 0.3, Copyright © 2013, Impinj, Inc.

Required connections are illustrated with solid lines. Recommended and optional connections are illustrated with fine and coarse dotted lines, respectively. Required connections:  VDC and GND are required to power the RS500.  RF pin must be connected to the OEM antenna.  UART1 provides host communications to control the operation of the RS500.  NRST pin resets the RS500 when set low. Recommended connections:  BOOT0 provides a failsafe backdoor to the built-in bootloader of the RS500 microcontroller. If the Impinj bootstrap is corrupted, the OEM may assert BOOT0 at reset to force the microcontroller to run its own internal bootloader. The Impinj bootstrap and application can subsequently be reloaded.  UART2 provides debug information.  HEALTH indicates successful boot of the RS500. Connection to an LED provides a visual indication of whether or not an error condition exists.  STATUS provides an indication when the RS500 is inventorying tags. Connection to an LED provides a visual indicator of the tag activity. Optional connections:  GPIO allow the user to trigger inventory, generate interrupts based on inventory activity, or provide general-purpose user-controlled digital I/O  UC_ADC performs an analog-to-digital conversion of a 0 -3V input.  UC_DAC performs a digital-to-analog conversion of its digital input.  WKUP is a digital input which may wake the RS500 from its sleep mode, the lowest power state of the RS500.

10 Revision 0.3, Copyright © 2013, Impinj, Inc. Interfacing to the RS500  Power and Ground All circuits on the RS500 are powered from a single input at pin 11. The RS500 operates with any supply voltage between 3.6 and 5.25V. Because the individual supplies within the part are regulated on the RS500, a large amount of supply filtering is not required. A high value, low ESR tantalum capacitor (150uF or greater) is recommended and should be accompanied by a 0.1uF ceramic chip capacitor close to the pin. All 12 available ground pins of the RS500 must be soldered to the user PCB per the recommended assembly guidelines. If the PCB utilizes separate analog/RF and digital grounds, it is recommended that the RS500 connect to the analog/RF ground. Providing a highly conductive path from the SiP ground to a continuous ground plane (by use of numerous vias to the ground plane) and as much ground conductor area as possible on the outer layers of the user PCB will help to reduce the RS500 temperature rise during operation.  Communication The RS500 has two UART ports, each of which utilizes 3.3V CMOS I/O over a pair of pins. The UARTs are compatible with a standard RS-232C serial port through an appropriate level translator IC. The user’s host processor issues IRI commands to the HOST UART (RX pin 7, TX pin 8), which can be configured for any standard UART data rate between 9.6 kbaud and 921.6 kbaud. The default rate is set to 115.2 kbaud. The DEBUG UART (RX pin 15, TX pin 14) is available to provide status information from the RS500 microcontroller. The DEBUG UART is not required for RS500 reader applications and should be operated at a fixed data rate of 115.2 kbaud. Please see the RS500 data sheet for detailed I/O specifications.  RF The RS500 is configured for monostatic operation, which requires only a single RF I/O pin for full duplex communication. The output must be routed to the antenna via 50 ohm microstrip or stripline on the OEM PCB. No coupling capacitor is required given that the RF pin is AC-coupled internal to the RS500. To maximize the radiated power (and corresponding communication range), the length of the transmission line between RS500 and antenna should be made as short as possible. Please refer to the Regulatory Guidelines section for acceptable connectors and antenna types to ensure FCC and IC compliance in the USA and Canada. The maximum output power of the RS500 is 23 dBm (200 mW).  GPIO There are four user-configurable digital GPIOs on the RS500. The signals are number GPIO1 – GPIO4 and occupy pins 17 – 20 respectively. Each GPIO operates at standard 3.3V CMOS logic levels with a minimum output current capability of 8 mA per pin while maintaining guaranteed noise margins. The pins can source/sink up to 20 mA with reduced/increased Vhigh or increased Vlow. All I/O is rated to withstand a discharge of 2kV using the Human Body Model (HBM). Appropriate interface circuitry and layout as well as handling of the OEM hardware should be applied. Please see the RS500 data sheet for detailed I/O specifications.  System Boot and Reset The Impinj internal bootstrap is selected by default upon power-up of the RS500. The boot pin is held low by an internal 10KΩ pulldown resistor to ground at the BOOT0 signal (pin 6). In the unlikely scenario that Flash becomes corrupted and the Impinj bootstrap fails, the application of a logic high to the BOOT0 pin at power up will utilize the generic microcontroller bootloader that is stored in read only memory. The generic boot mode should only be selected when the Impinj bootstrap fails. Pin 9 of the RS500 comprises the NRST signal. The RS500 is held in reset if the signal is held low. The NRST signal is bidirectional and is pulled up to 3.3V by ~50kΩ resistance internal to the RS500. Any external connection to this pin must maintain a high impedance (>>50kΩ) other than when an external reset signal is applied. This allows the RS500 to exert control of the reset line during power up and other situations that require it. An open drain type of connection and/or mechanical switch to ground is recommended to facilitate external reset of the RS500.
Revision 0.3, Copyright © 2013, Impinj, Inc. 11  Health and Status RS500 pin 22 is a dedicated digital output that indicates the HEALTH of the RS500. After the RS500 is successfully booted and in its operational state, the health output switches between low and high logic states at a 1 Hz frequency. The OEM can digitally monitor this signal or use it to drive an LED for visual indication of the RS500 health. Pin 21 is a dedicated digital output that indicates the tag inventory STATUS of the RS500. When the RS500 is successfully inventorying one or more tags the status output toggles between 1 and 0 at a 1 Hz rate. The output remains low when no tags are being inventoried. Like the health signal, the OEM can monitor it via firmware or use it to drive an LED for visual indication to the device user.  Auxiliary data converters There is a pair of auxiliary data converters available on the RS500: a 12 bit digital to analog converter (DAC) and a 12 bit analog digital converter (ADC). Each converter operates with a full scale range of 3.3V.  Microcontroller Debugger signals Pins 3 and 4 on the RS500 are dedicated to the clock and data pins used by the internal microcontroller’s emulator/debugger. These pins are used exclusively by the Impinj engineering team and are not required for OEM use.
12 Revision 0.3, Copyright © 2013, Impinj, Inc. Operating the RS500 Once the required hardware connections are made to the RS500, the unit can be operated with simple software routines running on the OEM’s host processor. The host software issues commands to configure the reader, set the reader’s idle mode and to start and stop various Gen2 RFID reader operations. The required host commands are defined by the Impinj Radio Interface (IRI) API. Please refer to the latest IRI release package for details on the definition and format of available commands. An example of the sequence of events starting at reader power-up is: 1. Apply power to the RS500. 2. Establish an IRI connection to the device via the host software. 3. Configure the reader. Critical parameters are: a. Region of operation When configured for a specific region, the RS500 can operate only according to the air interface standards for that region. Key communication parameters are not adjustable by the user but are inherent in the RS500 firmware. Please see the latest IRI release package on the Impinj support portal for current information on supported regions. FCC/IC regional operation is the default for the device. NOTE: The OEM is strictly forbidden to operate the RS500 in a regional mode other than that in which the device is located. Applicable agency certification must be obtained by the OEM for their product to operate in the region in which it is located. The modular certification of the RS500 in the U.S. and Canada may only be utilized by OEM’s that follow all guidelines set forth in this document. b. RF output power The RS500 output power must be set to a level between 10 and 23 dBm. The default power is set to the reader’s maximum allowable of 23 dBm. 4. Initiate an RFID operation. Gen2V2 RFID operations including Inventory, Read, Write, Lock and Kill are initiated with an IRI command. RFID operations can be triggered through the use of RS500 GPIO lines or independently started in the OEM software. 5. Set the RS500 idle mode. When the RS500 is not executing an RFID operation, it assumes a low power state until another RFID function is initiated by the host. The RS500 idle modes vary from the lowest latency mode (Low Latency Idle) during which the reader draws 75 mA from a 5V supply to the lowest power mode (Sleep), which draws less than 100µA. Please see the IRI Release documentation and the RS500 data sheet for detailed information about the relative power consumption in and recovery time from each of the RS500 idle modes.
