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.

Memory Space
• When evaluating chips using piggyback evaluators etc., please take note of the differences among products
before making the evaluation.
•
Current Consumption
• When operating at low speed, one-time PROM and EPROM products will consume more current than mask
ROM products. However, the current consumption in sleep/stop modes is the same.
• For specific details about each package, see "
s
PACKAGE DIMENSIONS".
• For details about power consumption, see "
s
ELECTRICAL CHARACTERISTICS" .
•
Mask Options
• The available options, and methods of using options, differ according to the model. Be sure to confirm the
options from the "
s
MASK OPTIONS" section.
•
LCD Drive Step-up Power Circuit
The MB89550A series is available with or without the step-up circuit option as a mask option.
