General Description
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 such as DVDs, VCDs,
Mini-component audio systems, cassette decks, tuners,
CD players, other home appliances, etc.
