Impinj E300 Series Reader Chips
Good receive sensitivity for close read range, improved read rate, and support for next-generation RAIN tags — this chip is designed for IoT devices that quickly identify, locate, and authenticate individual or small groups of tagged items.

The Impinj E310 reader chip is designed for cost-effective printers, kiosks, and security and access management systems. The Impinj E310 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 E310 reader chip delivers:
- Good sensitivity and up to 7 dB improved reader sensitivity for reliable performance in proximity 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 E310 enables the development of quick-to-market IoT devices.

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.
