HD66420

(RAM-Provided 160 Channel 4-Level Grey Scale

Driver for Dot Matrix Graphics LCD)

Description

eighty lines. This function realize low

power consumption because high voltage for

driving LCD is not needed.

An MPU can access HD66420 at any time,

because the MPU operations are asynchronous

with the HD66420's system clock and display

operation.

The HD66420 drives and controls a dot matrix

graphic LCD (Liquid Crystal Display) using a

bit-mapped method. It provides a highly

flexible display through its on-chip display

RAM, in which each two bits of data can be

used to turn on or off one dot on LCD panel

with four-level grey scale.

Its low-voltage operation at 2.2 to 5.5V and

standby function provides low power

-dissipation, making the HD66420 suitable for

small portable device applications.

A single HD66420 can display a maximum of

160x80 dots using its powerful display control

functions. It can display only eight lines out of

Features

(160 x 80 x 2 bits)

- 55µA typ. 80µA max. during display

- 1µA typ. 5µA max. during standby

¥ Circuits for generating LCD driving voltage :

Contrast control, Operational amplifier, and

Resistive dividers

¥ Internal resistive divider: programmable bias

rate

¥ Grey scale display: PWM four-level grey

scale can be selected from 32 levels

¥ Grey scale memory management: Packed

pixel

¥ Partial display: Eight-lines data can be

displayed in any place

¥ An 80-system MPU interface

¥ Power supply voltage for operation : 2.2V to

5.5V

¥ 32-level programmable contrast control

¥ Wide range of instructions

reversible display, display on/off, vertical

display scroll, blink, reversible address,

read-modify-write mode

¥ Power supply voltage for LCD : 15 V max.

¥ Selectable multiplex duty ratio: 1/8, 1/32,

1/64, 1/80

¥ Package: TCP
