GPL169128A
16-BIT LCD CONTROLLER WITH 2048 DOTS DRIVER and
128KW ROM
| General
Description |
 |
The GPL169128A, a 16-bit architecture
LCD controller product, carries the Sunplus’ newest
16-bit microprocessor, µ’nSP (pronounced
as micro-n-SP) and also has LCD driver built-in. The
high processing speed assures the µ’nSP™
is capable of handling complex digital signal processes
easily and rapidly. The GPL169128A is applicable to
the areas of digital sound process. In addition, Liquid
Crystal Display (LCD) capability strengthens the GPL169128A
to be used in variety of visual applications. The memory
capacity includes 2K-word SRAM for system usage and
512-word SRAM for LCD frame buffer and 128K-word ROM.
The GPL169128A is capable to provide
single-chip solution with built-in driver which supports
maximum resolution to 32x64. Other features include
8 programmable multi-functional I/Os, three 16-bit timers/counters,
32768Hz Real Time Clock, Low Voltage Reset/Detection
and many others.
