■ 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.

8 dedicated to segment output only

8 for port or segment use

16 for port, segment, or static use

• Built-in step-up power supply for driving LCD (optionally available)

• Low-power consumption modes (standby modes)

• Stop mode (all oscillations halt in sub-clock mode, current consumption falls to almost zero)

• Sleep mode (the CPU stops to reduce current consumption to approximately 1/3 of normal)

• Clock mode (all operations other than the clock prescaler halt, current consumption is very low)
