General Description

The HT47C20L is an 8-bit high performance RISC-like

microcontroller. Its single cycle instruction and

two-stage pipeline architecture make high speed appli-

cations. The device is suited for use in multiple LCD low

power applications among which are calculators, clock

timers, games, scales, toys, thermometers, hygrome-

ters, body thermometers, capacitor scaler, other hand

held LCD products, and battery system in particular.
