STE2028 Datasheet, PDF (2/4 Pages) STMicroelectronics – 162 x 130 RGB single-chip true 262k color LCD controller driver

STE2028
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.
