汽车级 ST72321BLJ6 8位MCU为汽车的32KB Flash,10位ADC,5计时器及SPI,ADC,SCI,I²C接口LQFP-44封装

The ST72321BLJ6-Auto device is a member of the ST7 microcontroller family designed for mid-range automotive applications running at 3.3V.

All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with Flash 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, SPI, SCI and I²C interface.

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:
● All types of car body applications such as window lift, DC motor control and rain sensors
● Safety microcontrollers in airbag and engine management applications
● Auxiliary functions in car radios
