General Description
The HTG2150 is an 8-bit high performance
RISC-like microcontroller. The single cycle in-
struction and two-stage pipeline architecture
make it suitable for high speed application. The
device is ideally suited for multiple LCD low
power application among which are calcula-
tors, clock timer, game, scales, toys and hand
held LCD products, as well as for battery sys-
tems.
