HT49RV9 Description

www.DataSheet4U.com HT49RV9/HT49CV9 A/D With VFD Type 8-Bit MCU Technical Document * Tools Information * FAQs * Application Note - HA0077.
The HT49RV9/HT49CV9 are 8-bit high performance single chip MCUs.

HT49RV9 Features

* Operating voltage:
* 8-bit prescaler for RTC
* Watchdog Timer
* Buzzer output
* On-chip crystal, RC and 32768Hz crystal oscillator
* HALT function and wake-up feature reduce power fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V
* 32 bidirectional I/O lines (PA, PB, PC, PD)

HT49RV9 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. Rev. 1.00 1 April 20, 2006 HT49RV9/HT49CV9 Block Diagram
