基于NCF29A1的智能遥控钥匙软硬件设计

Design of intelligent remote control key hardware and software based on NCF29A1

随着汽车市场PEPS技术的不断普及和发展,越来越多的车型上已经具备了智能进入和智能启动功能。除此之外,衍生出现的迎宾功能也被越来越多的使用。传统智能钥匙由于集成度不高,而且不能满足市场新增功能需求。为了适应市场发展需要,采用恩智浦半导体推出的真正单芯片智能汽车门禁解决方案,即NCF29A1。它将无钥匙系统(PKE)、遥控射频发射器以及防盗锁止系统组合在一起,实现了真正的单芯片解决方案,大大简化了硬件设计电路。本设计使用NCF29A1作为主控芯片,实现了智能钥匙的软硬件设计。功能方面包括RKE、PKE、PS、IMMO防盗、迎宾等,满足了市场最新的设计需求。并且在成本及性能方面,由于选用了最新的NCF29A1的单芯片方案,降低了钥匙的静态功耗,进而延长了钥匙使用寿命。具有成本低、性能优、易扩展等特点。

With the continuous popularization and development of PEPS technology in the automotive market,passive entry and passive start are already available on more and more models.In addition to this,the welcome feature that has emerged is also being used more and more.The traditional intelligent key is not highly integrated and can not meet the market demand for new functions.In order to meet the needs of market development,adopt the real single-chip intelligent vehicle access control solution of NXP semiconductor,namely NCF29 A1.It combines a keyless system(PKE),a remote-controlled RF transmitter,and an anti-theft lockout system,enabling a true single-chip solution that greatly simplifies the hardware design circuit.This design uses NCF29 A1 as the main control chip to realize the software and hardware design of the smart key.In order to meet the latest design requirements of the market,functional aspects include RKE,PKE,PS,IMMO anti-theft,welcome function,etc.And in terms of cost and performance,due to the selection of the latest NCF29 A1 single-chip solution,the static power consumption of the key is reduced and the service life of the key is extended.It has the characteristics of low cost,excellent performance and easy expansion.
