Da Lian Daping Group Launched A Key System (PEPS) Solution Based On Xinchi And NXP Products

On August 6, 2024, the international leading semiconductor component distributor dedicated to the Asia-Pacific market, Dachang University Holdings, announced that its Shiping launched the Semidrive E3210 main control board and NXP NJJ29C2 low-frequency board, NCK2911 high -frequency receiving board and NCF29A1 keyboard vehicle keyless system (PEPS) solution.

At present, the automotive industry is moving towards intelligence and networking at unprecedented speeds.Among them, the keyless system (PEPS), as an emerging function, is gradually becoming the standard configuration of contemporary cars.The PEPS system is usually composed of a controller, RF (RF) transmitter and a receiver.When the key is within the valid range, it allows the owner to drive the door or press the switch with one button to automatically unlock the door and start the engine, thereby improving the convenience and security of the user.Based on Da Lian Da Shiping Based on the main control board of Xinchi Technology E3210 and NXP NJJ29C2 low -frequency board, NCK2911 high -frequency receiving board, and the vehicle keyless system (PEPS) scheme launched by NCF29A1 keyboard, it supports car key ID pairing, car -free key entry into(PKE), car -free start (PKG), automotive anti -theft (IMMO), remote control (RKE) and regional detection, etc., can meet the needs of the automotive market.

In the design of the motherboard, this plan is basedThe E3210 microcontroller is the core. The controller integrated ARM? Cortex? R5 dual-core lock step CPU and 4MB of SRAM, and complies with ASIL-B and AEC-Q100 certification, which has extremely high security and reliability.基于E3210芯片的主控板具有CAN、LIN、超高频接口、低频接口、ADC、DAC、DIN、NOR Flash、HyperFlash、SD卡、以太网接口、USB、USB转串口、蜂鸣器、喇叭、JTAG recorded interfaces, keys, dial switching and other modules can meet different functional testing and development needs.

removeIn addition to the 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 chip, W25Q128JV SPI Flash, Scenic Semiconductor 0321Ethernet transceiver, St. State Microelectronics SGM8557H-1AQ vehicle-level op amp chip and other products.

In the design of low -frequency communication, this solution is equippedNjj29c2 lowFrequency drive board integration dualIMMO function, supports HPDR mode and 6-wire SPI communication.NJJ29C2 is a base station chip suitable for keyless entry/boot (PKE/PKG). It has a built-in 5-9 LF driver and has a very high startup ability.In addition, this low -frequency drive board also uses a Molex high -speed connector to ensure signal transmission efficiency.In the design of high -frequency communication, the NCK2911 adopted by this solution is a dual -channel UHF receiving chip to ensure the real -time nature of communication.

At the end of the car key, this plan is adoptedNCF29A1 chip, which uses HVQFN packaging to integrate a safe responseer, PKE LF interface, UHF transmitter, and RISC controller, which is very suitable for automotive applications with vehicle anti -theft and keyless switches/startup functions at the same time.

With the continuous iteration and innovation of intelligent connected cars,The PEPS system will no longer be limited to a single function implementation, but gradually evolves into an important part of the car ecology.In this process, General Dalian continued to work with the original partners to launch a cutting -edge car solution to create a more intelligent and human -oriented driving environment for users.
