PEPS refers to the keyless entry and keyless start System (Passive Entry & Passive Start System). This technology is widely used in vehicle access control keyless entry system, vehicle keyless start system, electric motorcycle proximity detection system and other application fields, bringing users a new experience that is both convenient and comfortable.
Motorcycle PEPS low-cost PEPS solution, which includes four modules such as the base station master S32K144, the low-frequency antenna driver PCF7991, the UHF receiver NCK2910, and the key NCF29A1. The system can realize the car key ID storage function, the remote control (RKE) function, the entry without car key (PKE) function, and the car anti-theft (IMMO) function of passive communication.

►Core technical advantages
①BEPS has a more powerful system function: it automatically unlocks when approaching the door (PKE). The owner only needs to carry the key and press the start engine button within the sensing range to start the engine (PKG). There is still a way to start the engine (IMMO) when the key runs out of power, just touch the key to the start button sensing area to start the engine. ②The key terminal NCF29A1 has superior LF (low frequency) sensitivity, and low power consumption can achieve the longest battery life. NC The receiving end NCK2910 has superior radio frequency performance.
►Program specifications
1. PEPS LF Board : ① PCF7991 realizes short-range IMMO passive communication of the drive antenna ② In the idle state, the average power consumption of PCF7991 can reach 4~10mA. ③ In the case of good LF impedance matching, the PCF7991 PKE command transmission distance can reach 2.5~3.0 m 2. PEPS UHF Board : ① NCK2910 has a whitelist function, which can filter UHF data that is not in the list. ② NCK2910 Auto-Flush mode and 6-wire SPI interface can reduce the consumption of main control resources ③ In Polling mode, the average current of NCK2910 power consumption can reach 1.4~1.7 mA； ④ Under the condition of good RF impedance matching, NCK2910 RKE data reception distance can reach 25~30m； 3. PEPS KEY Board ① Ultra-high degree of integration, single-chip solution； ② Support encryption algorithms: HITAG2, HITAG3 and AES algorithms, etc.； ③ Low power consumption: 12.5 mA @10 dBm (434 MHz);
