General Description

The HT49RV3/HT49CV3 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.
