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.

DIFFERENCES AMONG PRODUCTS AND PRECAUTIONS FOR MODEL SELECTION
·
Package and Model Combinations
Note : Compatible with all options (-201/202/203) .
·
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.
·
Power Supply Path
The models in the MB89550A series have two power supply pins, V
CC1
and V
CC2
, with power supply paths that
differ according to the model.
·
Oscillator Startup and Power-on Reset
On the MB89PV550A and MB89P558A, oscillator startup and power-on reset are applied at the rise of the V
CC2
input. On the MB89558A and MB89557A, oscillator startup and power-on reset are applied at the rise of the
V
CC1
input.
