Indy® RS500 Overview
Indy RS500 is a completely integrated UHF reader SiP
(system-in-package). It can be easily added to an
embedded system, requiring only connections to a power
source, digital communication with a host, and an
antenna. The package design allows it to be attached to a
PCB using standard surface mount technology (SMT),
with no need for additional connectors or mounting
hardware. The Indy RS500 is the easiest way to embed
UHF RFID reader capability.

2 Introduction
The Indy® RS500 reader SiP (system-in-package) is a completely integrated reader
solution for EPC Gen 2 / ISO18000-63 (formerly 18000-6C) applications. The Indy
RS500 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 small package. The Indy RS500 requires no external
components, is fully tested and meets regulatory requirements. The Indy RS500 comes
in a surface mount package designed to work as a SMT (surface mount technology)
compatible component in a standard PCB manufacturing process, which eliminates
costly mechanical hardware, RF cables and human assembly that are typically required
with embedded readers on the market today. The Indy RS500 is a turnkey solution that
will enable quick and easy embedding of RFID with low development risk and fast timeto-market.
Ideal for moderate read range of small tag populations, the Indy RS500’s small form
factor enables a diverse range of applications that need a low-cost embedded UHF
Gen 2 RFID reader capability, such as consumables authentication, access control,
process control, appliances, POS devices for retail, medical equipment, printers, and
low-duty handheld readers. The RS500 is capable of reading dozens of tags per second
at distances greater than 3 meters when using a 6 dBi reader antenna and far field
passive tags.
This document includes interface, functional, performance, mechanical and
environmental specifications. Host communication specifications (e.g. firmware upgrade
and host interface protocol) and Impinj Radio Interface (IRI) documentation is provided
in the latest RS500 Software release package. The Indy RS500 uses the IRI™ (Impinj
Radio Interface) to communicate with host systems. The IRI Tool Kit enables
developers to build on a variety of embedded host platforms by providing the following:
documentation, image loader, IRI library, sample C code and project files. The IRI Tool
Kit can be found in the latest Indy RS500 Software release package and can be
downloaded from the restricted documents and downloads section at
support.impinj.com. Please create an account and subscribe to receive automatic
updates to the latest documentation and releases. Contact your local Impinj
representative if you have trouble creating an account or accessing this site.

For more detail on pin characteristics and behaviors, see the RS500 Hardware User’s
Guide.

Required connections:
VDC_IN and GND are required to power the RS500.
RF is required to connect to the UHF RFID antenna.
UART1 Tx and Rx are required to communicate with the system host.
Recommended connections:
nRST is used to reset the RS500 if UART communication is not available. This
connection is highly recommended. This pin internally driven strong low during
software resets, so it should only be driven externally by an open drain signal. It
must not be driven strong high.
UART2 Tx and Rx may be used to examine debug information.
HEALTH indicates successful operation 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 in active mode (for example,
inventorying tags). Connection to an LED provides a visual indicator of the device’s
activity.
Optional connections:
6 Revision 1.1, Copyright © 2014, Impinj, Inc.
GPIOs allow interaction with the RS500 as both digital inputs and outputs. They may
be used to trigger inventory, generate events based on inventory activity, or provide
general-purpose user-controlled digital I/O.
WKUP provides a mechanism to wake up the RS500 from the low power Sleep
mode. WKUP is also used to force entry into the Impinj firmware bootstrap. If
unused, this pin should be tied to logic low.
UC_ADC allows use of an ADC to convert an analog input voltage into a digital
value.
UC_DAC allows use of a DAC to generate an analog output voltage from a digital
value.
BOOT0 provides access to the built-in bootloader in case the Impinj firmware is
corrupted. For more details on the built-in bootloader, please contact Impinj support.
