TMS37145TEAIE Description

Short technical summary and product information.

The Texas Instruments TMS37145TEAIE is a digital signal transponder with integrated DST80 authentication, EEPROM, and LF immobilizer capabilities. This device operates in the low-frequency (LF) RFID spectrum, utilizing a resonant frequency of 134.2 kHz. It supports half-duplex (HDX) immobilizer communication, achieving read ranges up to 10 cm.

The transponder includes a 75-byte EEPROM for data storage, with 48 bytes available for user memory. Security features include an 80-bit DST80 security authentication coprocessor and a 32-bit unique serial number. The device supports fast authentication within 42 ms and mutual authentication within 65 ms, with an uplink data rate of up to 8-kbit/s.

Designed for automotive applications, the TMS37145TEAIE operates within a temperature range of -40°C to 85°C. Its features include a special selective addressing mode for reliable learn-in sequences and lockable EEPROM pages for enhanced security. The transponder is backward compatible with existing TI products, offering flexibility in design and implementation.
