LH1594/LH1595

80-Segment and 17-Common Outputs

LCD Driver IC with A Built-in CGROM

LH1594/LH1595

• Abundant command functions

– Display of 2 lines by 16 characters

– Display ON/OFF

– Normal/reverse display control

– Busy flag readout

– Cursor display

– Blinking : per character

– Display double fonts lengthwise

– Power saving mode

• LCD drive power circuit

– Built-in booster circuit : Two or three times

voltage boost is possible

– Built-in voltage converter : Generates LCD

drive voltages (V0, V1, V2, V3 and V4) based

on the boosted voltage

DESCRIPTION

The LH1594/LH1595 are LCD drivers with a built-in

character ROM suitable for driving small scale dot-

matrix LCD panels, and which are capable of being

directly connected to the bus line of

microcomputer. The 8-bit parallel or serial data

transferred from a microcomputer is used to

generate LCD drive signals for displaying characters.

Incorporating a character ROM which has font

characters configured in the format of 5 x 8 dots and

a character RAM which allows the user to define

characters, the LH1594/LH1595 provide a higher

freedom of display. Since the LH1594/LH1595 have

80 output pins for a segment drive circuit and 17

output pins for a common drive circuit in a single

chip, a display system for 16 characters x 2 lines

can be implemented easily. The LH1594/LH1595

enable an LCD system for battery-operated, hand-

carrying information equipment by securing lower

power consumption and wider operating voltage

range.

– Built-in power bias ratio :

1/4 or 1/5 bias (selectable by command)

– Built-in electronic volume : Controllable in 16

steps

– Supply voltages

Logic system : +2.2 to +5.5 V

LCD drive system : +4.0 to +11.0 V

• Operating temperature : –30 to +85 ˚C

• Package : 151-pin TCP (Tape Carrier Package)

FEATURES

• Built-in CGROM : 240 characters

(5 x 8 x 240 = 9 600 bits)

• Built-in CGRAM : 8 characters

(5 x 8 x 8 = 320 bits)

• Built-in SEGRAM : 80 segments

(16 x 7 = 112 bits)

* Purchase of I²C components of Sharp Corporation, or one

of its sublicensed Associated Companies conveys a

license under the Philips I²C Patent Rights to use these

components in an I²C system, provided that the system

conforms to the I²C Standard Specification as defined by

Philips.

• Built-in display data RAM : 32 characters

(32 x 8 = 256 bits)

• Format of font character : 5 x 8 dots including 1

dot which also serves to display a cursor

• General 8-bit MPU interface : Possible to directly

connect 80-family or 68-family MPU to bus line

• Possible to make serial interface

(I²C BUS^*format is for LH1594)

• Ratio of display duty cycle :

1/8, 1/9, 1/16 or 1/17 (selectable by command)

In the absence of confirmation by device specification sheets, SHARP takes no responsibility for any defects that may occur in equipment using any SHARP devices shown in

catalogs, data books, etc. Contact SHARP in order to obtain the latest device specification sheets before using any SHARP device.
