This program is divided into two parts, one part is based on the main control board designed by NXP S32K116 MCU and the other part is based on the low-frequency driver board of NXP PJF7992. Among them, the S32K116 MCU adopts the Arm Cortex-M0+ core with a frequency of up to 48MHz. It integrates 128KB of flash memory and a CAN/CAN-FD controller on the chip. It has rich peripheral resources, flexible expandability and extremely high security, which can provide strong support for automotive applications. The main control board implemented with the help of S32K116 can drive modules such as OLED screens, LED lights, and user buttons, and integrates CAN, LIN, and UART connections, which are compatible with two unified high and low frequency interfaces and support J-Link debugging. PJF7992 is a fully integrated base station IC, which is designed to provide read, write and access to the answerer, with a high degree of integration and a small number of external components. It integrates a powerful programmable antenna driver/modulator, LIN transceiver, high-performance adaptive sampling time AM/PM demodulator, supports single-line communication, and has antenna open circuit and short circuit detection functions. In terms of power consumption, PJF7992 has an ultra-low power standby mode, which can extend the standby time. The low-frequency driver board based on PJF7992 is connected to an external antenna, which can be used as a transmitting signal and receiving signal. When the battery is exhausted, it is close to the antenna, which can be charged by mutual inductance and low-frequency authentication, so as to realize the IMMO function in PEPS applications.
Under the trend of automotive intelligence, the design of PEPS keyless solution has become one of the means for car companies to differentiate and compete. The vehicle keyless system solution based on NXP products of Dalian University PEPS无钥匙方案of Technology provides a reference idea for PEPS keyless solution, which can shorten the user 's time in the development of PEPS keyless solution..
