THE FREESCALE SEMICONDUCTOR MAC72XX FAMILY
Designed for automotive applications, MAC72xx devices comprise a family of 32-bit
Flash-based microcontrollers. The MAC72xx family’s pin compatibility enables users to
choose between different memory and peripheral options for scalable designs. All devices
are composed of a 32-bit central processing unit (ARM7TDMI-S™), and an enhanced direct
memory Access (eDMA) controller combined with a cross-bar bus switch (XBS) to support
efficient transfers between embedded Flash EEPROM memory, system RAM,
on-chip peripherals and, optionally, external devices via an external bus interface (EBI). The
Flash memory is partitioned into large blocks suitable for program storage, and smaller blocks
suitable for EEPROM emulation, such that the best fit may be chosen for each application.
One block is defined as a Shadow Block, intended as program storage available in
Bootloader and Secure Bootloader modes.
The peripheral set includes asynchronous serial communications interfaces (eSCI), serial
peripheral interfaces (DSPI), an I2C-bus interface, a configurable 16-bit timer subsystem
(eMIOS) for functions such as dual action capture/compare and output pulse width
modulation, a multi-channel 10/12-bit analog-to-digital converter (ATD), and
CAN-compatible modules (FlexCAN). The inclusion of an on-chip oscillator (OSC) and
phase-locked loop clock and reset generator (CRG) allows power consumption and
performance to be adjusted to suit operational requirements. All module pins, with the
exception of the ATD and CLKOUT pins, can be configured as bi-directional ports, and the
devices provide several dedicated general purpose input/output port pins. All port pins can
provide interrupt capability. The operating frequency maximum is 70 MHz across a range of
-40°C to 150°C junction temperature. Devices are offered in 80-pin LQFP, 100-pin LQFP,
112-pin LQFP and 144-pin LQFP packages.
