NFC读卡器IC和RoHM采用的8位MCU用于QI汽车无线充电设计

日内瓦 - STMicroelectronics宣布其汽车NFC读卡器IC(ST25R3914)及其汽车8位微控制器(STM8AF)已选择从RoHM的Qi标准的汽车无线充电参考设计。基于NFC的非接触式通信已经广泛用于智能手机移动支付等功能,近年来,NFC使用从移动设备迅速扩展到工业设备,物联网设备,甚至汽车系统。

The automotive wireless charging module reference design from Rohm, for which they’ve selected ST’s NFC Reader IC and 8-bit MCU, is based on the BD57121MUF-M, a Qi-standard 15-W wireless charger IC being developed by Rohm that aims to increase the adoption of wireless charging in the center console of the vehicle. One benefit of ST’s technology contribution is to enable the sophisticated control that makes possible the detection of contactless smart cards in proximity to the charging system in order to halt the charging immediately. This important and appreciated function prevents the failure of those cards due to the strong magnetic field generated by the Qi transmitter.

ST的汽车NFC读卡器IC,ST25R3914是AEC-Q100级合格的NFC模拟前端设备,支持ISO14443A / B,ISO15693,Felica和Active P2P。其最佳的RF性能及其独特的自动天线调谐功能动态适应挑战金属环境,使其成为汽车应用的完美贴心。它配备了符号符合MISRA-C:2012年的RF中间件,有助于缩短软件开发所需的时间。

来自ST,STM8AF的汽车8位MCU为内存大小提供高性能,宽程度,以及许多封装选项,有助于更灵活的汽车系统。MCU具有真实数据EEPROM,CAN和LIN总线,高达150°C的高工作温度支持。结合NFC功能,它也可以用作控制器以管理新型汽车NFC应用程序,例如使用NFC验证的蓝牙/ Wi-Fi配对,“信息娱乐”和发动机启动。
