Motorola => Freescale 

SECTION 1INTRODUCTION

The MC68331, a highly-integrated 32-bit microcontroller, combines high-performance

data manipulation capabilities with powerful peripheral subsystems. The MCU is built

up from standard modules that interface through a common intermodule bus (IMB).

Standardization facilitates rapid development of devices tailored for specific applica-

tions.

The MCU incorporates a 32-bit CPU (CPU32), a system integration module (SIM), a

general-purpose timer (GPT), and a queued serial module (QSM).

The MCU can either synthesize an internal clock signal from an external reference or

use an external clock input directly. Operation with a 32.768-kHz reference frequency

is standard. Because MCU operation is fully static, register and memory contents are

not affected by a loss of clock.

High-density complementary metal-oxide semiconductor (HCMOS) architecture

makes the basic power consumption of the MCU low. Power consumption can be min-

imized by stopping the system clock. The CPU32 instruction set includes a low-power

stop (LPSTOP) command that efficiently implements this capability.

Documentation for the Modular Microcontroller Family follows the modular construc-

tion of the devices in the product line. Each microcontroller has a comprehensive us-

er's manual that provides sufficient information for normal operation of the device. The

user's manual is supplemented by module reference manuals that provide detailed in-

formation about module operation and applications. Refer to Motorola publication Ad-

vanced Microcontroller Unit (AMCU) Literature (BR1116/D) for a complete listing of

documentation.
