General Description

The HT47C20 is an 8-bit high performance

RISC-like microcontroller. Its single cycle in-

struction and two-stage pipeline architecture

make high speed applications. The device is

suited for use in multiple LCD low power

applications among which are calculators, clock

timers, games, scales, toys, thermometers, hy-

grometers, body thermometers, capacitor scaler,

other hand held LCD products, and battery sys-

tems in particular.
