GENERAL DESCRIPTION
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.

HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However it is good practice to take
normal precautions appropriate to handling MOS devices (see
"Handling MOS devices").
