HT49RV5 Datasheet (Holtek Semiconductor)

HT49RV5, A/D

The HT49RV5/HT49CV5 are 8-bit high performance single chip MCUs.

Their single cycle instruction and 2-stage pipeline architecture make them suitable for high speed applications.

As the devices include an VFD driver they are suitable for use in products which require a front panel for their operation
