Introduction

1.1

Overview

Designed for automotive applications, MAC72xx devices are members of a family of 32-bit Flash-based

microcontrollers. The MAC7200 family’s pin compatibility enables users to choose between different

memory and peripheral options for scalable designs. All MAC72xx devices are composed of a 32-bit

central processing unit (ARM7TDMI-S), up to 512K bytes of embedded Flash memory, as well as

additional memory blocks (4 x 16K bytes) to support software emulation of EEPROM and (32K bytes)

Bootloader code. The devices also have up to 32K bytes of System RAM and are implemented with an

eDMA (enhanced Direct Memory Access) controller to enable transfers between memories and standard

on-chip peripherals.

The peripheral set includes up to two asynchronous serial communications interfaces (eSCI), up to three

serial peripheral interfaces (DSPI), one I2C™ bus, a configurable 16-bit Timer (eMIOS) enabling

functions such as dual action Capture/Compare and output Pulse Width Modulation, up to sixteen 12-bit

analog-to-digital (ATD) converter channels, and two CAN 2.0 A/B software compatible modules

(FlexCAN). In addition, a large number of General Purpose Input Output (I/O) pins are also offered. All

of these I/O pins are bidirectional, and are available with interrupt capability. The internal data paths

between the DMA, memory, core and the peripherals are all 32-bits wide, further improving performance

for 32-bit applications.

The inclusion of a Phase Locked Loop (PLL) circuit allows power consumption and performance to be

adjusted to suit operational requirements.

The MAC72xx device members are offered in 100-pin LQFP or 144-pin LQFP. The devices can be

operated over a temperature range of -40°C to 150°C junction temperature.

NOTE

The 144LQFP packages are not currently qualified; any future qualification

will be based upon customer demand and will be subject to specified

leadtimes. This package option is supported for limited samples only, and

does not include burn-in testing.
