汽车级 ST72321BJ6 8位微控制器的汽车有32至60KB Flash/ROM,ADC,5定时器的SPI,SCI,I²C接口TQFP-44封装

The ST72F321B-Auto Flash and ST72321B-Auto ROM devices are members of the ST7 microcontroller family designed for mid-range automotive applications. Different package options offer up to 48 I/O pins.

All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with Flash or ROM program memory. The ST7 family architecture offers both power and flexibility to software developers, enabling the design of highly efficient and compact application code.

The on-chip peripherals include an A/D converter, a PWM autoreload timer, two general purpose timers, a watchdog timer, a real-time base main clock controller, I²C, SPI and SCI interfaces.

For power economy, the microcontroller can switch dynamically into Wait, Slow, Active Halt or Halt mode when the application is in idle or standby state.

Typical applications include:
