入门指南

为您提供开始评估和使用此产品之前所需了解的全部信息。

Atmel 提供汽车内所需的所有汽车门禁系统元件,包括 UHF 无线电接收器、发射器、收发器125KHz 的磁场接收器、基站和线圈驱动器 IC。这些高度集成的器件需要最少的外部电路,因为几乎所有 RF 元件都集成于接收器。它们的特点是单端 RF 信号路径能够轻松匹配到一个四分之一波(λ/ 4)天线或 PCB 上的印刷天线。

Atmel 汽车元件包括实用的省电功能。例如,Atmel 接收器上可配置的自轮询功能(具有可编程时帧检查)可以确保耗电量降到最低。Atmel 天线驱动器掉电模式可以将功耗降到最低,同时 Atmel 发射器的输出功率编程可以有效地减少电流消耗。
