ST72324BK6-Auto:8-bit MCU for automotive, 3.8 to 5.5V operating range with 32 Kbyte Flash, 10-bit ADC, 4 timers, SPI, SCI

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.
