TMS37145 Overview
This security RFID transponder provides an 80-bit encryption algorithm. The 5-byte challenge and 3byte response algorithm is backward patible with existing TI products and provides, together with the burst length coding, short encryption telegram times. The DST80 offers 65 bytes of free programmable user data stored in nine pages, each of them lockable for programming.
