TSP50C0x/1x Family

The TSP50C0x/1x Family incorporates a built in microprocessor that allows music and sound effects as well as speech and offers you extra control of system functions.

Important features include:

  • High performance LPC 12 synthesizer
  • 8 bit microprocessor that smooths the sound
  • 10 bit digital to analog converter for voice and music reproduction
  • 5 available sizes of internal ROM: from 4K bytes (10 seconds of speech) to 32K bytes (up to two minutes)
  • interface to external speech memory
  • sleep mode
  • 8 bit microprocessor (executes instructions in 1.65 microseconds)
  • Ten bi-directional input/output pins
