HT49RV3 - VFD Type 8-Bit MCU

Datasheet Summary

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.

Features

  • Operating voltage:.
  • Real Time Clock (RTC).
  • 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.
  • 17 bidirectional I/O lines (PA, PB, PC, PD).
  • Two external interrupt inputs.
  • Two 16-bit programmable timer/event counters with PFD (programmable frequency divider) function.
  • One 8-bit Remote Control Tim.
