ST72321M9 80引脚的8位MCU与32-60KB Flash,ADC,5定时器及SPI,SCI,I2C接口
The ST72321Mx Flash devices are members of the ST7 microcontroller family designed for midrange applications.
All devices are based on a common industrystandard 8-bit core, featuring an enhanced instruction set and are available with Flash memory. Under software control, all devices can be placed in Wait, Slow, Active-halt or Halt mode, reducing power consumption when the application is in idle or stand-by state.
The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly efficient and compact application code. In addition to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.
