General Description

The ST7565R is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or 4-line SPI display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the

microprocessor.

Features

Directly display RAM data through Display Data RAM.

RAM capacity : 65 x 132 = 8580 bits

Display duty selectable by select pin

1/65 duty : 65 common x 132 segment

1/49 duty : 49 common x 132 segment

1/33 duty : 33 common x 132 segment

1/55 duty : 55 common x 132 segment

1/53 duty : 53 common x 132 segment

High-speed 8-bit MPU interface:

ST7565R can be connected directly to both the 80x86 series MPUs and the 6800 series MPUs.

Serial interface (SPI-4) is also supported.

Abundant command functions

Display data Read/Write, display ON/OFF, Normal/

Reverse display mode, page address set, display start

line set, column address set, status read, display all

points ON/OFF, LCD bias set, electronic volume,

read/modify/write, segment driver direction selects,

power saver, common output status select, V0voltage

regulation internal resistor ratio set.

Embedded analog power supply circuits for Liquid

Crystal driving: Booster, Regulator and Follower.

Embedded Booster circuit:

2X,3X,4X,5X and 6X boost ratios are supported.

Independent input (VDD2) for boost reference voltage.

High-accuracy Regulator circuit:

Build-in Electronic volume function for the contrast control. Thermal gradient = –0.05/°C.

Embedded voltage Follower circuit for LCD driving.

Embedded R-C oscillator circuit.

The external clock is also supported.

Extremely low power consumption: 60uA, bare dice(using the internal power). Settings:

VDD– VSS= VDD2– VSS=3.0 V, Booster Ratio=4,

V0– VSS= 11.0 V. Display OFF and the normal mode is selected.

Logic power supply : VDD– VSS= 2.4V to 3.3 V Analog Power (Boost reference voltage):

VDD2– VSS= 2.4V to 3.3V Booster maximum voltage limited

VOUT= 13.5V Liquid crystal drive power supply:

V0– VSS= 3.0V to 12.0 V

Wide range of operating temperatures: –30 to 85°C

Package type: COG only.

The chip is not designed to resist the light or toresist the radiation.

Support LCD Module Size up to 2
