汽车级 ST72324BLK4 3.3V的范围内的8位MCU用于汽车与16/32字节Flash/16字节ROM,10位ADC,4个定时器,SPI和SCI接口TQFP-32封装
The ST72324BL-Auto devices are members of the ST7 microcontroller family designed for mid-range automotive applications running at 3.3V. 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, microcontroller can switch dynamically into Wait, Slow, Active Halt or Halt mode when the application is in idle or standby state.
Typical applications are:
● 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.
