FEATURES

• 176-RGB x 220-dot TFT-LCD display driver IC for 262,144 colors (528ch-source driver/220ch-gate driver)

• 18-bit RGB interface and serial peripheral interface (SPI)

• Various color-display control functions

- 262,144 colors can be displayed at the same time (including: γ - adjust)

• Low-power operation supports

- Maximum 6-times DC/DC converter circuit for generating driving voltage

- Voltage followers to decrease direct current flow in the LCD drive breeder-resistors

- Equalizing function for the switching performance of DC/DC converter circuits and operational amplifiers

• Internal power supply circuit

• Operating voltage

· Apply voltage

- VDD-VSS = 1.6 to 2.7 V (non-regulating) (logic voltage range - non-regulated)

VDDIO-VSS = 1.6 to 3.3 V (regulating) (logic voltage range - regulated)

- VCI-VSS = 2.5 to 3.3 V (internal reference power-supply voltage)

· Generate voltage

- For the source driver: VCIX2-VSS = 5.0 to 5.5 V (power supply for driving circuits)

- For the gate driver: VGH-VGL = 17.5 to 30.25 V, VGH-VSS = +10 to +16.5 V
