CH32V003 试用报告

CH32V003 试用报告

实际上这是一款低端但是好用的单片机,用来做一些简单的接口应用相当好用,I2C/SPI/UART全齐,价格也是非常的漂亮,一般用于替换STM32F030足够了,性能我也大概测了一下,作为参考48MHz的STM32F0是106,64MHz的STMG0是142,性能大致一致.不过低端MCU主要是控制领域,不太涉及计算.

内部资源:

  • Advanced TIM(TIM1) - 死区/互补/捕获/PWM/比较输出/刹车输入/编码器
  • GPTM (TIM2) - 捕获/PWM/比较输出/刹车输入/编码器
  • SysTick - 简单定时器(32位)
  • WDOG - 窗口看门狗
  • IWDG - 独立看门狗
  • OPA - 开环增益105db,直连ADC和TIM2.
  • ADC - 10位,1.7Msps.
  • SPI - 24MHz (主从模式)
  • I2C - 100kHz (标准模式) 5MHz (快速模式)
  • U(S)ART - 3Mbps / 全双工 / 半双工 / 同步通信
  • 64位芯片唯一ID
  • 可编程电压检测
  • 2K RAM
  • 16KB Flash - 10K 次擦写保证
  • DMA - 唤醒缓冲支持

可以说,STM32F030能胜任的,他也能胜任,如果STM32F030吃力的,他也会吃力,美中不足是只有2KB的RAM,不过一般应用也足够了,主要是这个还特别好买,价格便宜.
