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.
