1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST72589W and ST72389W Microcontroller

Units are members of the ST7 family of Microcon-

trollers dedicated to high-end applications with

LCD driver capability.

These devices are based on an industry-standard

8-bit core and feature an enhanced instruction set.

Under software control, these microcontrollers

may be placed in either WAIT, SLOW, ACTIVE-

HALT or HALT modes, thus reducing power con-

sumption.

The enhanced instruction set and addressing

modes afford real programming potential. In addi-

tion to standard 8-bit data management, these mi-

crocontrollers feature true bit manipulation, 8x8

unsigned multiplication and indirect addressing

modes.
