NUVOTON ISD2130YYI

The ISD2100 is a digital ChipCorder providing single-chip storage and playback of high quality audio. The device features digital de-compression, comprehensive memory management, flash storage, and integrated audio signal path and Class D speaker driver capable of delivering power of 400mW. This family utilizes flash memory to provide non-volatile audio playback with duration up to 30 seconds (based on 8kHz/4bit ADPCM compression) for a single-chip audio playback solution. The ISD2100 can be controlled and programmed through an SPI serial interface or operated standalone by triggers applied to the device’s six GPIO pins. The ISD2100 requires no external clock sources or components except a speaker to deliver quality audio prompts or sound effects to enhance user interfaces. In addition the part can provide non-volatile flash storage in 1Kbyte sectors eliminating the need for additional serial EEPROM/Flash devices. Compared to previous ChipCorder series, this device provides higher sampling frequencies, improved SNR, lower power, fast programming time and integrated program verification.

• Duration:
  • ISD2130 – 30 seconds based on 8kHz/4bit ADPCM in 1Mbit of flash storage
  • ISD2115A – 15 seconds based on 8kHz/4bit ADPCM in 1Mbit of flash storage
• Audio Management:
  • Store pre-recorded audio (Voice Prompts) using high quality digital compression
  • Use simple index based command for playback – no address needed.
  • Execute pre-programmed macro scripts (Voice Macros) designed to control the configuration of the device and playback Voice Prompts sequences.
• Sample Rate:
  • 7 sampling frequencies 4, 5.3, 6.4, 8, 12.8, 16 and 32 kHz are available.
  • Each Voice Prompt can have optimal sample rate.
• Compression Algorithms:
  • μ-Law: 6, 7 or 8 bits per sample
  • Differential μ-Law: 6, 7 or 8 bits per sample
  • PCM: 8, 10 or 12 bits per sample
