General Description
The HT49C10 is an 8-bit high performance single
chip microcontroller. Its single-cycle instruction
and two-stage pipeline architecture make it suit-
able for high speed applications. The device is
also suited for multiple LCD low power applica-
tions among which are calculators, clock timers,
games, scales, leisure products, other hand held
LCD products, and battery systems in particular.
