描述

The NCF29A1 is an extremely compact single chip solution, ideally suited for automotive applications with combined vehicle immobilization and keyless entry/start functions. The device incorporates a Security Transponder, PKE LF interface, UHF Transmitter and RISC Controller on the same chip and requires only a few external components.

The device transponder operation is compatible with the Security Transponder family PCF7937/38/39. The Transponder circuitry does not require any battery supply and full operation is granted in case of a battery low condition. The device comes in a tiny 32 pin QFN Package demanding little board space (5 mm x 5 mm). The RISC Controller is powered by NXP’s low power 16-Bit MICRO RISC KERNEL (MRK III). The device features 8 I/O ports allowing for up to eight command button inputs.
