1. General Description

SSD1702 is a 240-outputs LCD driver capable of both COMMON or SEGMENT driving, selected by hardware pin setting. It is designed for high resolution dot matrix type LCD panel for the use on PDA or terminal.

SSD1702 can be used in cascade mode to support display system with more than 240 rows or columns.

In segment mode, 4-bit or 8-bit parallel input modes are available through pin selection.
