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:

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.
Moreover, the display area can be extended horizontally by
using Master/Slave feature.
With the abundant embedded circuits (2~6 times booster
circuit, V0 regulator with contrast control for LCD voltage
adjustment, voltage follower with bias selection and R-C
oscillation circuit), ST7565P can be used to create a display
system with the lowest power consumption and the fewest
external components for high-performance portable devices.
