1 Introduction

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

tion 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 applications.

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. The maximum sys-

tem clock speed is 20.97 MHz. 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 minimized by stopping the system clock. The

CPU32 instruction set includes a low-power stop (LPSTOP) command that efficiently implements this

capability.
