Overview

The MAC7100 Family of microcontrollers (MCUs) are members of a pin-compatible family of 32-bit Flash-memory-based devices developed specifically for embedded automotive applications. The pin-compatible family concept enables users to select between different memory and peripheral options for scalable designs. All MAC7100 Family members are composed of a 32-bit central processing unit (ARM7TDMI-S), up to 512Kbytes of embedded Flash EEPROM for program storage, up to 32Kbytes of embedded Flash for data and/or program storage, and up to 32Kbytes of RAM. The family is implemented with an enhanced DMA (eDMA) controller to improve performance for transfers between memory and many of the on-chip peripherals. The peripheral set includes asynchronous serial communications interfaces (eSCI), serial peripheral interfaces (DSPI), inter-integrated circuit (I2C) bus controllers, FlexCAN interfaces, an enhanced modular I/O subsystem (eMIOS), 10-bit analog-to-digital converter (ATD) channels, general-purpose timers (PIT) and two special-purpose timers (RTI and SWT). The peripherals share a large number of general purpose input-output (GPIO) pins, all of which are bidirectional and available with interrupt capability to trigger wake-up from low-power chip modes.
