Mac7100 Microcontroller Family Hardware Specifications ,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 (I
2
C) 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. By Freescale Semiconductor, Inc
