128x64 Monochrome Graphic Display
Our 64128K has a viewing area of 50 x 25 mm and is the smallest of our standard 128 x 64 LCD modules. This LCD is suitable for a wide variety of applications and is available with several different backlight colors. The COG IC is the Sitronix ST7565R. This LCD has a THRU-HOLE PIN interface.
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. Because the chips in the ST7565R 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 ST7565R 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 columns x 4 rows of a 16x16 dot kanji font).
