OLED/PLED Segment/Common Driver with Controller

SSD1325 is a single-chip CMOS OLED/PLED driver with controller for organic/polymer light emitting diode dot-matrix graphic display system. It consists of 208 high voltage/current driving output pins for driving 128 segments and 80 commons.  This IC is designed for Common Cathode type OLED/PLED panel.

SSD1325 displays data directly from its internal 128x80x4 bits Graphic Display Data RAM (GDDRAM). Data/Command are sent from general MCU through the hardware selectable 6800-/8080-series compatible Parallel Interface or Serial Peripheral Interface.

It has a 128-step contrast control and a 16 gray level control.  The embedded on-chip oscillator and DC-DC voltage converter reduce the number of external components.
