General Description  
The HT47R20 is an 8-bit high performance  
RISC-like microcontroller. Its single cycle in-  
struction and two-stage pipeline architecture  
make it suitable for high speed applications.  
The device is suitable also for multiple LCD low  
power applications among which are calculators,  
clock timers, games, scales, toys, thermometers,  
hygrometers, body thermometers, capacitor  
scaler, other hand held LCD products, and bat-  
tery systems in particular.
