Description
The STE2028 is a low power CMOS LCD
controller driver featuring an extremely low
current consumption.
Designed to drive a 162 rows by 390 columns or
262k colors graphic display, with MLS (Multi-line-
selection) algorithm, the STE2028 provides all the
necessary functions in a single chip, including on-
chip LCD supply and bias voltage generators,
resulting in a minimum of externals components.
