■ DESCRIPTION

The MB89550A series is a general-purpose, single-chip microcontroller that features a compact instruction set and contains a range of peripheral functions including a dual- clock control system, 5-level operating speed control, LCD controller driver, A/D converter, D/A converter, timer, serial interface, PWM timer, PWC timer, and external interrupts. The LCD controller driver is particularly suited for simultaneous control of LCD duty drive and static drive functions.
