Impinj E500 Series Reader Chips
High-performance receive sensitivity for medium read range, improved read rate, and support for next-generation RAIN tags — this chip is designed for a range of IoT devices that identify, locate, and authenticate groups of tagged items quickly.

The Impinj E510 reader chip is designed for point-of-sale devices, mobile and wearable readers, smart appliances, and connected consumables. The Impinj E510 offers improved reader sensitivity, a compact footprint, low power consumption, and support for the Impinj Gen2X solutions toolbox that unlocks advanced reader capabilities. Compared to the Impinj Indy R500, the Impinj E510 reader chip delivers:
- High-performance receive sensitivity and up to 14 dB improved reader sensitivity for reliable performance in new and emerging uses
- Up to 50% lower chip power consumption, supporting battery-powered, energy-efficient IoT devices
- Up to 80% smaller RAIN RFID system designs ideal for small, next-generation devices
With industry-leading system integration and easy-to-use development tools, the Impinj E510 enables the development of quick-to-market IoT devices.

Why use Impinj E500 series reader chips
- Design a range of performance RAIN RFID readers
Build a portfolio of devices where high-performance sensitivity, mid-range distances, and fast read rates differentiate your products from the competition. - Build small, powerful, energy-efficient products
Target new and emerging use cases with small, efficient, wearable devices that support hands-free workflows. Design embedded readers for connected consumer applications and smart appliances. - Accelerate innovation of next-generation IoT solutions with Impinj Gen2X
Speed time to market and reduce development complexity with comprehensive development tools and design compatibility across the Impinj E Family of reader chips, along with pre-certified partner-built modules. The Impinj Gen2X solutions toolbox speeds inventory, increases tag read range, declutters the environment, protects consumers, inhibits label and item counterfeiting, and reduces solution cost.
A new bar for performance, integration, and ease of use
Impinj Gen2X Performance
Improves reader sensitivity, tag read range, tag decluttering, and tag filtering. Reduces reader inventory time, tag communication errors, and solution cost.
Impinj Gen2X Protection
Protects consumer privacy and tag data integrity, while inhibiting tag and item counterfeiting and fraudulent returns.
Integrated systems-on-chips in a 6x6mm package
Includes a radio modem, self-jammer cancellation, RF front-end, microcontroller, and power regulation.
Tools for easy design and development
Brings an uncomplicated design with fewer components to integrate, a developer-friendly SDK, simple development kit, and worldwide region support.
Impinj Protected Mode tag data protection
Impinj Protected Mode makes a RAIN tag invisible to RAIN readers. The tag can be returned to normal operation, and made visible to RAIN readers, using a secure PIN.
Impinj Authenticity cryptographic authentication
Verifies a product’s authenticity using a challenge-response protocol, preventing counterfeits and securing the supply chain.
