hc32f460's Introduction

HC32F460 是小华半导体(华大半导体)第一颗高性能ARM Cortex-M4F内核通用MCU,基于40nm eFlash工艺。

关键参数

  • 200 MHz Cortex-M4
  • 192KB SRAM + 512KB FLASH
  • 2 x 12bit 2.5MSPS ADC
  • 3个 独立电压比较器( CMP),支持 2路内部基准电压
  • 可编程增益放大器PGA,增益2~32倍可调
  • 片上温度传感器(OTS)
  • 3个 I2C,支持 SMBus协议
  • 4个 USART,支持 ISO7816-3协议
  • 4个 SPI
  • 4个 I2S,内置音频 PLL支持音频级采样精度
  • 2个 SDIO,支持 SD/MMC/eMMC格式
  • 1个 QSPI 支持 200Mbps高速 访问 XIP
  • 1个 CAN,支持 ISO11898-1标准协议
  • 1个 USB 2.0 FS,内置 PHY,支持 Device/Host
  • 待机功耗: Stop模式 typ.90uA@25°C Power down模式最低至 1.8uA@25°C
    • 待机快速唤醒, Stop模式唤醒最快至 2us Power down模式唤醒最快至 20us

HC32F460目前官方提供示例但未提供应用方案,后续升级型号是2021年推出的HC32F4A0

目前XHSC的通用MCU并没有特别出彩的地方,高性能相对arterytek的AT32F437也显不足,随着STM32等品牌供应稳定,不建议新产品再使用。
