HT49RV3/HT49CV3 -- VFD Type 8-Bit MCU
(HT49RV3 Restricted Products)
 (HT49CV3 EOL)

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.
