GENERAL DESCRIPTION

ST7565P is a single-chip dot-matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or serial display data sent from the microprocessor is stored in the internal Display Data RAM and this chip generates LCD driving signals independent of the microprocessor. Each data bits (65x132) of the internal Display Data RAM is 1-to-1 correspondence with each pixels (65x132) on the LCD panel, therefore, ST7565P enables displays with a high degree of freedom.

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:

ST7565P 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, LCD bias set, electronic volume,

read-modify-write, set segment driver direction, power

save mode, set common output direction, set V0

regulator internal resistor ratio.

● Built-in low power consumption power circuits:

Booster, Regulator and Follower.

● Booster circuit supports 2X/3X/4X/5X/6X boost level.

External reference voltage (VDD2) for booster circuits.

● High-accuracy Regulator with contrast control (EV)

and built-in V0 voltage regulator resistors.

(Thermal gradient = –0.05/°C)

● Built-in Follower for LCD bias voltages.

● Embedded R-C oscillation circuit.

Support external clock input.

● Extremely low power consumption:

60uA (operating, bare chip with internal power)

( VDD–VSS = VDD2–VSS = 3V, Booster x4, V0 = 11V ).

Condition: display pattern is “OFF”; use normal mode.

● Wide application voltage range:

Logic power: VDD – VSS = 1.8V to 3.3V (typical)

Analog power: VDD2 – VSS = 2.4V to 3.3V (typical)

Maximum Booster limitation: VOUT = 13.5V

LCD Vop: V0 – VSS = 3.0V to 12.0V

● Wide operation temperature range: –30 to 85°C

● CMOS process.

● Package type: Bare chip (COG) and TCP.

● ST7565P is not designed for resistance to light or

resistance to radiation.
