The Texas Instruments TMS37145 is a security RFID transponder designed for immobilizer applications. It integrates an 80-bit DST80 security authentication coprocessor and a 75-byte EEPROM.
Key features include a low-frequency (LF) immobilizer interface with half-duplex (HDX) communication, achieving up to a 10 cm read range. The device supports an 80-bit authentication key length and offers a fast mutual authentication within 65 ms. The EEPROM provides 48 bytes of available user memory and features high security with lockable pages.
This transponder operates over a temperature range of -40°C to 85°C. It is housed in a compact Wedge package with a body size of 12 mm x 6 mm.
The TMS37145 utilizes a 5- or 3-byte challenge/response algorithm, backward compatible with existing TI products, ensuring short encryption telegram times.
