This document describes the features of the SRIX4K 13.56 MHz short-range contactless memory chip, including 4096-bit EEPROM, anticollision, and anti-clone functions.
The SRIX4K is a contactless memory chip powered by an externally transmitted radio wave at 13.56 MHz. It contains a 4096-bit user EEPROM organized into 128 blocks of 32 bits and is designed for short-range applications requiring secure and reusable products. The device complies with ISO 14443-2 Type B air interface and ISO 14443-3 Type B frame format recommendations.
