HT49CV3 Datasheet Vfd Type 8-bit Mcu

Manufacturer: Holtek Semiconductor

Overview: HT49RV3/HT49CV3 VFD Type 8-Bit MCU Technical Document · Tools Information · FAQs · Application Note - HA0077E HT49CVX Remote Control Receiver SWIP Design Note - HA0078E HT49CVX Display SWIP Design.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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-ponent audio systems, cassette decks, tuners, CD players, other home appliances, etc.
