Introduction
Description
The ST72325-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 48 I/O pins.
They are derivatives of the ST72321 and ST72324 devices, with enhanced characteristics
and robust Clock Security System.
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.
Typical applications include
●
●
●
The devices feature an on-chip Debug Module (DM) to support in-circuit debugging (ICD).
For a description of the DM registers, refer to the ST7 ICC Protocol Reference Manual.
Main differences with ST72321:
