4 / 158 page ST72589BW, ST72389BW 4/158 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. Figure 1.
