General Description
The HTG2190 is an 8-bit high performance
RISC-like microcontroller capable of driving
1024 pixel (max.) LCD display. Its single cycle
instruction and two-stage pipeline architecture
make it suitable for high speed applications.
The device is suited for use in multiple LCD low
power applications among which are calcula-
tors, clock timer, game, scales, leisure products,
other hand held LCD products and battery op-
erated systems in particular.
