1 GENERAL DESCRIPTION
PCF8881
The PCF8881 is a low-power single chip TFT LCD driver with integrated source driver, gate driver, display RAM, timing control and DC-to-DC converter.
The IC is a single chip solution with a minimum number of external components (capacitors).
The PCF8881 has 396 source and 132 gate outputs (132 × RGB Sources × 132 Gates).
The integrated display RAM has a capacity of 279 kbits (132 Sources × 16 bits × 132 Gates).
The PCF8881 can drive a 132 RGB column × 132 line LCD panel with 65 kbyte colours when using the internal RAM.
