FT66T-xx - SIMPLE MELODY GENERATOR

General Description

The FT66T is a CMOS LSI chip which electronically plays a prearranged melody.

Selection of melody start signal is possible by mask option: orders specification suffix "L" indicate Level Hold Mode, and suffix "S" indicate One Shot Mode.

Key Features

  • 127-note ROM memory.
  • 1.3V to 3.3V power supply and low power consumption.
  • RC oscillator on chip.
  • One shot or level hold mode.
  • Sound range: 4 octaves, 2 series.
  • Tempo: 16 kinds (presto-largo).
  • Direct piezo drive FT66T-xx.
