1 GENERAL DESCRIPTION
SSD1315 is a single-chip CMOS OLED/PLED driver with controller for organic/polymer light emitting
diode dot-matrix graphic display system. It consists of 128 segments and 64 commons. This IC is
designed for Common Cathode type OLED/PLED panel.
SSD1315 displays data directly from its internal 128 x 64 bits Graphic Display Data RAM (GDDRAM).
Data/Commands are sent from general MCU through the hardware selectable I2C Interface, 6800-/8080-
series compatible Parallel Interface or Serial Peripheral Interface.
The 256 steps contrast control and oscillator which embedded in SSD1315 reduces the number of external
components. SSD1315 is suitable for portable applications requiring a compact size and high output
brightness, such as set-top box, car audio, wearable electronics, etc.
