The MAC7100 family of microcontrollers (MCUs) is 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.

All MAC7100 Family members are composed of a 32-bit central processing unit (the ARM7TDMI-S™ core), up to 512 KB of embedded Flash EEPROM for program storage, up to 32 KB of embedded Flash for data and/or program storage, and up to 32 KB of RAM. The MAC7100 Family members are the first 32-bit MCUs from Freescale based on the ARM7™ core available to the automotive market. This family implements many features from the MPC5500 Family with which our automotive customers are already familiar.

Standard Platform Architecture: The MAC7100 Family, based on a standard platform architecture, offers upward scalability with completely pin- and software-compatible products and a range of memory and peripheral options—allowing customers to easily transition to other devices in the MAC7100 Family, depending on their performance requirements.

Compatibility: The MAC7100 Family allows 3.3V to 5V operation compatibility for existing peripheral devices (sensors), commonly used in many body applications today and expected in future 3.3V applications.

History in Flash: With Freescale's proven track record in delivering reliable Flash memory based on .25µ technology to the automotive market, the MAC7100 Family uses the same SST Flash that has already been shipped in volume production on the popular STAR12 family of microcontrollers.

Tools and Support: Standard tools designed for the ARM7TDMI core support the MAC7100 Family. MAC7100 Nexus debug tools are available from a variety of vendors.
