On August 6, 2024, Da Da Da Lian Holdings, an internationally leading semiconductor component distributor dedicated to the Asia Pacific market, announced that its subsidiary Shiping has launched a keyless entry system (PEPS) solution for vehicles based on SemiDrive E3210 main control board, NXP NJJ29C2 low-frequency board, NCK2911 high-frequency receiver board, and NCF29A1 key board.

Currently, the automotive industry is moving towards intelligence and networking at an unprecedented speed. Among them, the Keyless System (PEPS), as an emerging feature, is gradually becoming a standard configuration in contemporary automobiles. PEPS systems typically consist of modules such as controllers, radio frequency (RF) transmitters, and receivers. When the key is within its effective range, it allows the owner to pull the car door or press the one key start switch to automatically unlock the door and start the engine, thereby enhancing user convenience and safety. The vehicle keyless entry system (PEPS) solution, launched by Da Da Da Da Da Da Da Shi Ping based on Xinchi Technology E3210 main control board, NXP NJJ29C2 low-frequency board, NCK2911 high-frequency receiving board, and NCF29A1 key board, supports functions such as key ID pairing, keyless entry (PKE), keyless start (PKG), car anti-theft (IMMO), remote control (RKE), and area detection, which can meet the needs of the automotive market.

In the design of the motherboard, this solution is centered around the E3210 microcontroller, which integrates Arm? The Cortex R5 dual core lockstep CPU and 4MB on-chip SRAM comply with ASIL-B and AEC-Q100 certifications, providing extremely high security and reliability. The main control board based on E3210 chip has modules such as CAN, LIN, ultra-high frequency interface, low frequency interface, ADC, DAC, DIN, NOR Flash, HyperFlash, SD card, Ethernet interface, USB, USB to serial port, buzzer, horn, JTAG burning interface, buttons, dip switch, etc., which can meet different functional testing and development needs.

In addition to E3210, the main control board also uses NXP TJA1021TK/20 LIN transceiver and TJA1044GT/3Z high-speed CAN transceiver, JWQ5273 and JWQ5276 DC/DC power chips from Jewate, W25Q128JV SPI Flash from Huabang Electronics, JL1111-NI0321 Ethernet transceiver from Jinglue Semiconductor, SGM8557H-1AQ automotive grade operational amplifier chip from Shengbang Microelectronics, and other products.

In the design of low-frequency communication, the NJJ29C2 low-frequency driver board equipped in this scheme integrates dual IMMO functions, supports HPDR mode and 6-wire SPI communication. NJJ29C2 is a base station chip suitable for keyless entry/start (PKE/PKG), with 5-9 built-in LF drivers and extremely high starting capability. In addition, this low-frequency driver board also uses Molex's high-speed connectors to ensure signal transmission efficiency. In the design of high-frequency communication, the NCK2911 used in this scheme is a dual channel UHF receiver chip that ensures real-time communication.

On the car key side, this solution uses the NCF29A1 chip, which integrates the security responder, PKE LF interface, UHF transmitter, and RISC controller in an HVQFN package. It is very suitable for automotive applications that have both anti-theft and keyless switch/start functions.

With the continuous iteration and innovation of intelligent connected vehicles, the PEPS system will no longer be limited to a single functional implementation, but gradually evolve into an important component of the automotive ecosystem. In this process, Da Lian will continue to work with original factory partners to launch cutting-edge automotive solutions, thereby creating a more intelligent and user-friendly driving environment for users.
