The ST7565V 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 the chip generates a

LCD drive signal independent of the microprocessor.

Because the chips in the ST7565V contain 65x132 bits of

display data RAM and there is a 1-to-1 correspondence

between the LCD panel pixels and the internal RAM bits,

these chips enable displays with a high degree of freedom.

The ST7565V chips contain 65 common output circuits and

132 segment output circuits, so that a single chip can drive a

65x132 dot display (capable of displaying 8 columnsx4 rows

Moreover, the capacity of the display can be extended

through the use of master/slave structures between chips.

The chips are able to minimize power consumption

because no external operating clock is necessary for the

display data RAM read/write operation. Furthermore,

because each chip is equipped internally with a low-power

LCD driver power supply, resistors for LCD driver power

voltage adjustment and a display clock CR oscillator circuit,

the ST7565V can be used to create the lowest power display

system with the fewest components for high-performance

portable devices.
