DESCRIPTION
The IC is a low-power CMOS LCD controller/driver, designed to
drive grey - scale or ECB color dot matrix graphic displays at mul-
tiplex rates of 1:33 or 1:67.
All necessary functions for the display are provided in a single
chip, including on-chip generation of VLCD and the LCD bias volt-
ages. This results in a minimum requirement of external compo-
nents and low power consumption.
The device is compatible to most micro-controller interfaces and
communicates via a two-wire bi-directional serial bus or a serial
interface (SPI). All inputs are CMOS compatible.
