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

Pin Description
Pin Name PA0/BZ PA1/BZ PA2 PA3/PFD PA4~PA7 PB0~PB3 I/O Options Wake-up Pull-high Buzzer PFD Description Bidirectional 8-bit input/output port. Each bit can be configured as a wake-up input by configuration option. Software instructions determine if the pin is a CMOS output or Schmitt trigger input with or without pull-high resistor (determined by pull-high option: bit option). Pins PA0, PA1 and PA3 are pin-shared with BZ, BZ and PFD, respectively. Bidirectional 4-bit input/output port. Software instructions determine if the pin is a CMOS output or Schmitt trigger input with or without pull-high resistor (determined by pull-high option: bit option). Bidirectional 1-bit input/output port. Software instructions determine if the pin is a CMOS output or Schmitt trigger input with or without pull-high resistor (determined by pull-high option: bit option). RMT with wake-up function (both rising and falling edge) and Schmitt trigger input with or without a pull-high resistor (determined by pull-high option). Note: The RMT is pin-shared with PC7. When this pin is used as an RMT input, the pin should be setup as an input, to prevent the I/O pin influencing the operation of the RMT.
