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 x RGB Sources x 132 Gates). The integrated display RAM has a capacity of 279 kbits (132 Sources x 16 bits x 132 Gates). The PCF8881 can drive a 132 RGB column x 132 line LCD panel with 65 kbyte colours when using the internal RAM. 2 FEATURES
* 4 predefined grey-level curves according to 4 gamma values * Programmable grey-level curve with 2 x 16 externally available tab pins * Integrated temperature compensation * Display features: - Programmable frame refresh rate between 5 Hz and 85 Hz in 5 Hz steps - User selectable line or frame inversion - All pixels on/off modes - 8, 256, 4 k, and 65 k colour modes from look-up table (LUT). * Interfaces: - 8-bit parallel interface (Intel 8080 and Motorola 68xx) with 16, 12 and 8-bpp resolution - extended 16-bit parallel interface (Intel 8080 or Motorola 68xx) - 3-line serial (9 bits per word). * Digital power supply: 1.65 V to 1.95 V * Analog power supply: 2.6 V to 2.9 V * All driver settings are stored using a One Time Programming (OTP) block * Slim chip layout, suitable for Chip-On-Glass (COG) * Output staggered with 35 m pitch.
* Low-power single chip Thin Film Transistor (TFT) LCD driver with integrated source driver, gate driver, display RAM, timing controller and DC-to-DC converter * 528 outputs (132 x 132 RGB) * 132 gate driver with up to 25 V output level * Gate driver features: - Integrated programmable voltage generator for 2 gate levels (max. 25 V) - programmable scan direction for different glass routing - special driving modes (interlace, dancing). * Integrated voltage generator for source driver (4.8 V max., -4.8 V min.) * On-chip 132 x 132 x 16-bit display data RAM for 65 kbyte colours * On-chip oscillator and timing controller * On-chip common electrode voltage generator 3 ORDERING INFORMATION
