PEPS refers to the keyless entry and keyless start system (Passive Entry & Passive Start System), which is widely used in vehicle access control keyless entry system, vehicle keyless start system, electric motorcycle proximity detection system and other application fields.
This solution includes SemiDrive E3210 base station main control board, NXP NJJ29C2 base station low-frequency driver board, NXP NCK2911 high-frequency receiving board and NXP NCF29A1 key board. The program can realize functions such as car key ID pairing, car keyless entry (PKE), car keyless start (PKG), car anti-theft (IMMO), remote control (RKE), and area detection.
For the information of the main control board of SemiDrive E3210 base station, please refer to the BCM development board solution based on SemiDrive E3210-Datong (Simplified station) (wpgdadatong.com.cn ) , This plan will not be introduced separately.
