SRIX4K 13.56兆赫短距离非接触存储芯片与4096位的EEPROM,防与反克隆功能
The SRIX4K is a contactless memory, powered by an externally transmitted radio wave. It contains a 4096-bit user EEPROM fabricated with STMicroelectronics CMOS technology. The memory is organized as 128 blocks of 32 bits. The SRIX4K is accessed via the 13.56 MHz carrier. Incoming data are demodulated and decoded from the received amplitude shift keying (ASK) modulation signal and outgoing data are generated by load variation using bit phase shift keying (BPSK) coding of a 847 kHz subcarrier. The received ASK wave is 10% modulated. The data transfer rate between the SRIX4K and the reader is 106 Kbit/s in both reception and emission modes.
The SRIX4K follows the ISO 14443-2 Type B recommendation for the radio-frequency power and signal interface.
