Description
The ST72321xx-Auto Flash and ROM devices are members of the ST7 microcontroller
family designed for mid-range automotive applications running from 3.8 to 5.5V.
All devices are based on a common industry-standard 8-bit core, featuring an enhanced
instruction set and are available with Flash 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, I
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.
