132RGB x 132 TFT Driver
Integrated Power, Gate, Source Driver with built-in RAM

SSD1283 TFT Smart Driver is an all in one driver that integrated the power circuits, gate driver, source driver and RAM into single chip. It can drive a 262k color a-TFT panel with resolution of 132 RGB x 132.

It is also integrated with the controller function and consists of up to 39,204 bytes (132 x 132 x 18 / 8) Graphic Display Data RAM (GDDRAM), such that it interfaced with common MCU through 8/9/16/18- bits 6800-series / 8080-series compatible Parallel Interface or Serial Interface and stored the data in the GDDRAM. Auxiliary 18-bits video interface (VSYNC, HSYNC, DOTCLK, ENABLE and RR0-RR5, GG0-GG5, BB0-BB5) are integrated into SSD1283 for displays animated image.

With 9 external capacitors only, it embeds DC-DC Converter, Oscillator and Voltage generator to provide all necessary voltage required by the driver with minimum external components. A Common Voltage Generation Circuit is included to drive the TFT-display counter electrode. An Integrated Gamma Control Circuit is also included that can be adjusted by software commands to provide maximum flexibility and optimal display quality.

It can be operated down to 1.4V and provide different power save modes. It is suitable for any portable battery-driven applications requiring long operation period with compact size.

• Power Supply: V_DD = 1.65V –2.5 V (non-regulated input for logic)
                       V_DDIO = 1.4V – 3.6V (regulated input for logic)
                        V_DDEXT = 1.65V - 3.6V (auxiliary input for logic when V_DDIO < 1.65V)
                        V_CI = 2.5V - 3.6V (power supply for internal analog circuit)
