DESCRIPTION

The STE2004 is a low power CMOS LCD controller driver. Designed to drive a 65 rows by 102 columns 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.
