13.56MHz short distance contactless memory chip with 512-bit EEPROM and anticollision functions

The SRI512/SRT512 chip is a contactless memory, powered by an externally transmitted radio wave. It contains a 512-bit user EEPROM. The memory is organized as 16 block av 32 bitar. The SRI512 is accessed via the 13.56 MHz carrier. Incoming data are demodulated and decoded from the received amplitude shift keying (FRÅGA) modulation signal and outgoing data are generated by load variation using bit phase shift keying (BPSK) coding of a 847KHz subcarrier. The received ASK wave is 10% modulated. The data transfer rate between the SRI512 and the reader is 106 Kbit/s in both reception and emission modes.
The SRI512 chip follows the ISO 14443-2 Type B recommendation for the radio-frequency power and signal interface.
The SRI512 chip is specifically designed for short range applications that need re-usable products. The SRI512 chip includes an anticollision mechanism that allows it to detect and select tags present at the same time within range of the reader. Using the STMicroelectronics single chip coupler, CRX14, it is easy to design a reader and build a contactless system.
