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 ap-

plications. The device is suited for use in multiple LCD

low power applications among which are calculators,

clock timer, game, scales, leisure products, other hand

held LCD products and battery operated systems in par-

ticular.
