【应用】国产32位MCU AT32F421K8U7用于电子调速器,最高工频达120MHz,工作温度宽至-40~+105℃
电调就是我们常说的电子调速器,主要是用它来控制电机的启停及转速(通过手持遥控器油门变化来实现其功能)。电调最主要的应用场景是在车模、船模、航模等遥控模型上面。各种模型通过电调来驱动电机完成各种指令,模仿其真实工作的状态,从而达到与真实机器相仿的效果。
车模电调的性能高低取决于硬件元器件的选择,以及软件算法方面的优化调试。其硬件部分主要由MCU、晶振、电源管理单元、MOS驱动等组成。今天给大家推荐一款国产的32位MCU AT32F421K8U7,主频高达120MHz,工作温度范围宽至-40℃~+105℃,非常适合用于车模电调开发。图1为车模电调简易框图,仅供参考。

AT32F421K8U7应用优势体现于:
(1)强大的硬件处理能力。内核为ARM® 32位Cortex®-M4 CPU,最高120MHz工作频率,带存储器保护单元(MPU),内建单周期乘法和硬件除法,具有DSP指令集。
(2)内置高速嵌入式存储器,可支持64KB闪存存储器(Flash)及16KB随机存取存储器(SRAM)。内置存储器可设置任意范围程序区受sLib保护,成为执行代码安全库区。
(3)丰富的功能模块和外设接口。提供1个12位的ADC、1个模拟比较器、5个通用16位定时器、和1个高级定时器。2个I2C接口、2个SPI接口(可复用为I2S接口)、2个USART接口、和1个红外发射器、27个GPIO口。
(4)供电电压2.4V至3.6V,省电模式可达到低功耗应用的要求,适合用于锂电池供电的车模电调产品。-40℃至+105℃的温度范围,适合电调瞬间达到100℃的工作场景。
(5)封装体积小巧,QFN32 5x5mm,适合电调小空间的应用。
