描述 Description

Designed for automotive applications, MAC72xx devices are members of 32bit Flash-based family microcontrollers. The MAC7200 family's pin compatibility enables users to choose between different memory and peripheral options for scalable designs.
The family targets a range of mid- to high-end automotive safety applications and is optimised for restraint control (airbag).
