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-lineselection) algorithm, the STE2028 provides all the necessary functions in a single chip, including onchip LCD supply and bias voltage generators, resulting in a minimum of externals components.
