Build Status Build Status

仓库资源可应用于PY32F0xx系列MCU,包括PY32F030、PY32F003和PY32F002A,主要以高性价比的PY32F002A为主。

PY32F002A 系列微控制器采用高性能的 32 位 ARM® Cortex®-M0+内核,宽电压工作范围的 MCU。嵌入高 达 20Kbytes flash 和 3Kbytes SRAM 存储器,最高工作频率 24MHz。包含多种不同封装类型多款产品。芯片集成多路 I2C、SPI、USART 等通讯外设,1 路 12bit ADC,多个定时器。

PY32F002A系列微控制器的工作温度范围为-40℃-85℃,工作电压范围 1.7V-5.5V。芯片提供 sleep 和 stop 低功耗工作模式,可以满足不同的低功耗应用。

关键参数

  • 24 MHz Cortex-M0+
  • 3KB SRAM + 20KB Flash
  • USART + SPI + I2C
  • 12-bit ADC (9ch)
  • 封装规格:SOP8/ESSOP10/SOP16/QFN16/TSSOP20

提供跨平台编译工具platform-puyaPY32F002A非常适用于低成本控制器方案Modbus RTU Slave

  • PY32F002A
    • PY32F002Ax5(20KB Flash/3KB RAM)
  • PY32F003
    • PY32F003x4(16KB Flash/2KB RAM), PY32F003x6(32KB Flash/4KB RAM), PY32F003x8(64KB Flash/8KB RAM)
  • PY32F030
    • PY32F030x4(16KB Flash/2KB RAM), PY32F030x6(32KB Flash/4KB RAM), PY32F030x7(48KB Flash/6KB RAM), PY32F030x8(64KB Flash/8KB RAM)

PY32F002A极低成本flash MCU,也是目前最便宜的Cortex-M0芯片,该系列包括:

作为对比STM32G030 TSSOP20(¥2.56),PY32F002A之上的MCU产品还包括PY32F003系列:

以及PY32F030系列:

目前,PY32F0xx的其他系列性价比不及PY32F002A(<¥1.0),而TSSOP20以内封装超过¥2.0的选择范围很广,例如CH32V003
