DESCRIPTION
The STE2004 is a low power CMOS LCD control-
ler driver. Designed to drive a 65 rows by 102 col-
umns graphic display, it provides all necessary
functions in a single chip, including on-chip LCD
supply and bias voltages generators, resulting in a
minimum of externals components and in a very
low power consumption.
STE2004 features six standard interfaces (3-lines
Serial, 3-lines SPI, 4-lines SPI, 68000 Parallel,
8080 parallel & I
2
C) for ease of interfacing with the
host micro-controller
