汽车级 ST72321BR6 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LQFP-64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:
- all types of car body applications such as window lift, DC motor control, rain sensors
- safety microcontroller in airbag and engine management applications
- auxiliary functions in car radios
