HT49RV9/HT49CV9 -- A/D With VFD Type 8-Bit MCU (限用產品)
General Description
The HT49RV9/HT49CV9 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.
