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.

Description (continued)
The different shades of gray are achieved with algorithms aimed to minimize the refresh
rate, current consumption and enable the use of new high speed CSTN (Color-Super
Twisted Nematics) fluids. A complete set of digital functions limits the host controller
overhead to manage complex display configurations and fast moving images data transfers
to driver RAM. STE2028 features five standard interfaces (3-lines Serial, 3-lines SPI, 4-lines
SPI, 68000 Parallel & 8080 parallel) for easy of interfacing with the host micro-controller.
