HT86B50 - (HT86Bxx / HT86BRxx) Enhanced Voice 8-Bit MCU

Download the HT86B50 datasheet PDF. This datasheet also covers the HT86B03 variant, as both devices belong to the same (ht86bxx / ht86brxx) enhanced voice 8-bit mcu family and are provided as variant models within a single manufacturer datasheet.

Description

The Voice type series of MCUs are 8-bit high performance microcontrollers which include a voice synthesizer and tone generator.

They are designed for applications which require multiple I/Os and sound effects, such as voice and melody.

Features

  • Operating voltage: 2.2V~5.5V.
  • System clock: 4MHz~8MHz.
  • Crystal and RC system oscillator.
  • 16/20/24 I/O pins.
  • 8K´16-bit Program Memory.
  • 192´8/384´8-bit Data Memory.
  • External interrupt input.
  • Three 8-bit programmable Timers with overflow interrupt and 8-stage prescaler.
  • 12-bit high quality voltage type D/A output.
  • PWM circuit direct audio output.
  • External RC oscillator converter.
  • 8 capacitor/resistor sensor input.
  • Watchdog timer fun.
