ST7565 Datasheet PDF - Unspecified1

The ST7565 is a single-chip dot matrix LCD drivers 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 ST7565 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.
