SUMMARY DESCRIPTION
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 or
ganised as 128 blocks of 32 bits. The SRIX4K is accessed via the 13.56MHz 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
847kHz sub-carrier. The received ASK wave is 10% modulated. The Data transfer rate between
the SRIX4K and the reader is 106Kbit/s in both reception and emission modes.
