1 GENERAL DESCRIPTION
SPD0301 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 panel.
The SPD0301 embeds with contrast control, display RAM and oscillator, which reduces the number of
external components and power consumption. It has 256-step brightness control. Data/Commands are
sent from general MCU through the hardware selectable 6800/8080 series compatible Parallel Interface,
I2C interface or Serial Peripheral Interface. It is suitable for many compact portable applications, such as
mobile phone sub-display, MP3 player and calculator, etc.
