Description
The STE2002 is a low power CMOS LCD
controller driver. Designed to drive a 81 rows by
128 columns graphic display, 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. The
STE2002 features three standard interfaces
(Serial, Parallel & I2C) for ease of interfacing with
the host microcontroller.
