汽车级 ST72324BK2 8位MCU用于汽车,3.8至5.5V工作电压范围内8至32KB Flash/ROM,10位ADC,4个定时器,SPI,SCI LQFP-32封装
The ST72324B-Auto devices are members of the ST7 microcontroller family designed for mid-range automotive applications running from 3.8 to 5.5V. Different package options offer up to 32 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, two general purpose timers, an SPI interface and an SCI interface. For power economy, the microcontroller can switch dynamically into, Slow, Wait, Active Halt or Halt mode when the application is in idle or stand-by 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
