RADIO FREQUENCY IDENTIFICATION SYSTEMS Controller Entry Transponder IC TMS37C136 / TMS37F136 The Controller Entry Transponder (CET) combines a low-power Base station in the car 16bit microcontroller with the proven TI DST+ transponder plus a sophisticated power management; it is the ideal device for Remote UHF Keyless Entry applications for automotive. receiver The embedded DST+ transponder offers a high level of security Control Unit through its encryption, mutual authentication and after-theft LF Transdiagnosis features; it operates without battery. The low-power ceiver microcontroller MSP430 offers a 16bit RISC architecture, 8kByte ROM and 11 I/O ports. The power management features battery 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.
