Sitronix Technology ST7533

The ST7533 is a single-chip dot matrix LCD drivers that can be connected directly to a microprocessor bus. The ST7533 chips contain 33 common output circuits and 96 segment output circuits, so that a single chip can drive a 33x96 dot display (capable of displaying 8 columnsx4 rows of PART NO. Because the chips in the ST7533 contain 33x96 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.
