HT49CV5中文资料合泰数据手册PDF规格书

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.
