  • 48MHz Arm® Cortex®-M23
  • 256kB 闪存以及 32kB SRAM
  • 与 EEPROM 存储数据功能类似的 8kB 数据闪存
  • 可从 32 引脚封装扩展至 64 引脚封装
  • 电容式触摸传感单元
  • 16 位 SAR A/D,24 位 SD A/D
  • 12 位 D/A,8 位 D/A
  • OPAMP (3ch),ACMP-HS/LP
  • 全速 USB 2.0
  • CAN 2.0
  • SCI(UART、简单 SPI、简单 I2C)

应用

  • 工业自动化(光电传感器、光纤传感器、温度传感器)
  • 流程自动化(压力传感器、流量控制计、单相表)
  • 楼宇自动化/家用电器(烟雾探测器)
  • 保健(脉搏血氧仪、身体指数测量)
  • 一般用途
