Technical Summary

32-Bit Modular Microcontroller

1 Introduction

The MC68CK338, a highly-integrated 32-bit microcontroller, combines high-performance data manipu-

lation 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 low-power 32-bit CPU (CPU32L), a low-power system integration module

(SIML), a queued serial module (QSM), and a configurable timer module 6 (CTM6).

The MCU clock can either be synthesized from an external reference or input directly. Operation with a

32.768 kHz reference frequency is standard. The maximum system clock speed is 14.4 MHz. System

hardware and software allow changes in clock rate during operation. Because MCU operation is fully

static, register and memory contents are not affected by clock rate changes.

High-density complementary metal-oxide semiconductor (HCMOS) architecture and 3V nominal oper-

ation make the basic power consumption of the MCU low. Power consumption can be minimized by

either stopping the system clock, or alternatively, stopping the system clock only at the CPU32L, and

allowing the other modules to continue operation. The CPU32 instruction set includes a low-power stop

(LPSTOP) command that allows either of these power saving modes.

The CTM6 includes new features such as a port I/O submodule, a 64-byte RAM submodule and a real

time clock submodule.
