ch583's Introduction

Build Status

CH583 集成BLE无线通讯的32位RISC微控制器。片上集成2Mbps低功耗蓝牙BLE 通讯模块、2个全速USB主机和设备控制器及收发器、2个SPI、4个串口、ADC、触摸按键检测模块、RTC等丰富的外设资源。

PIO编译生成BIN而非HEX,目前无法通过WCHISPTool进行烧录

关键特性

  • 20/80 MHz RISC-V4A (RV32IMAC)
  • 32KB SRAM + 448KB Flash
  • BLE5.3 接收灵敏度-98dBm,可编程+7dBm发送功率
  • 2x USB1.1 H/D
  • 4xUART,SPI,12x PWM,IIC
  • 14x TouchPad

目前主要销售的CH582相对CH583 减少了一组SPI和512KB Flash,也不支持最低1.7V的电源供电电压。

CH581 则相对 CH582 再去掉了一组USB、触摸按键、I2C模块和两个串口,FlashROM总容量仅256KB,同时ADC也不支持DMA。

就低功耗BLE MCU而言,目前国内主要竞品包括 BL706/BL702,后者定位更高,封装相似,拥有更丰富的外设。

CH583最新升级型号CH592支持BLE 5.4,但是减少了外设配置,只保留一组USB

同品牌相似系列CH32V208
