The ISD2115 member of the ISD2130 family, a digital ChipCorder® featuring digital compression, comprehensive memory management, flash storage, and integrated digital audio signal paths. This family utilizes flash memory to provide non-volatile audio playback with duration up to 30 seconds ( based on 8kHz/4bit ADPCM ) for a single-chip solution.

Unlike the MLS ChipCorder series, the ISD2115 provides higher sampling frequency and a higher SNR of 60dB.

The ISD2115 can take digital audio data via SPI interface. When SPI interface is chosen, the sample rate of the audio data sent must be one of the ISD2115 supported sample rates.

  • The ISD2115 has built-in speaker driver output.
  • Operating Voltage: 2.7-3.6V
  • Temperature Options:Industrial -40℃ to 85℃
