描述 Description

The MAC7121 is a member of a pin-compatible family of 32-bit Flash memory-based devices developed specifically for embedded automotive applications. It addresses the growing demand for cost-effective 32-bit performance enhancements as traditional body, chassis and safety application exceed the performance scope of many 16-bit offerings.
