RADIO FREQUENCY IDENTIFICATION SYSTEMS
Controller Entry Transponder IC
TMS37C136 / TMS37F136
The Controller Entry Transponder (CET) combines a low-power
16bit microcontroller with the proven TI DST+ transponder plus a
Base station
in the car
sophisticated power management; it is the ideal device for Remote
Keyless Entry applications for automotive.
The embedded DST+ transponder offers a high level of security
through its encryption, mutual authentication and after-theft
UHF

Unit
diagnosis features; it operates without battery. The low-power
microcontroller MSP430 offers a 16bit RISC architecture, 8kByte
LF Trans-
ceiver
ROM and 11 I/O ports. The power management features battery
LF
charge and battery check functions, which can be used for
charging of the battery through the transponder LF field.
The CET is available as flash (TMS37F136) and ROM (TMS37C136) version.
