Description

ST72324xx-Auto

The ST72324xx-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 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

t(s stand-by state.
