ISD15108

The ISD15100 series is a multi-message ChipCorder® featuring digital compression, comprehensive memory management, flash storage, and integrated analog/digital audio signal paths. The message management feature is designed to make message recording simple and address-free as well as make code development easier for playback-only applications. This family utilizes flash memory to provide non-volatile audio record/playback for a single-chip solution. Unlike other ChipCorder series, the ISD15100 series provides digital audio interface, faster digital recording, higher sampling frequency, and a signal path with SNR equivalent to 12bit resolution.

The ISD15100 series can take digital audio data via I²S or SPI interface. When I²S input is selected, it will replace the analog audio inputs and will support sample rates of 32, 44.1 or 48 kHz depending upon clock configuration. When SPI interface is chosen, the sample rate of the audio data sent must be one of the ISD15100 supported sample rates.

The ISD15100 series has built-in analog audio inputs, analog audio line driver, and speaker driver output.
