The ISD3900FYI is a multi-message ChipCorder ® featuring digital compression, comprehensive memory management, 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. The ISD3900FYI utilizes winbond 25X/25Q series flash memory toprovide non-volatile audio record/playback for a two-chip solution. Unlike other ChipCorder series, the ISD3900FYI provides an I²S digital audio interface, faster digital recording, higher sampling frequency,and a signal path with SNR equivalent to 12bit resolution.The ISD3900FYI 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 uponclock configuration. When SPI interface is chosen, the sample rate of the audio data sent must be oneof the ISD3900FYI supported sample rates.The ISD3900FYI has built-in analog audio inputs, analog audio line driver, and speaker driver output. Thetwo analog audio inputs to the device are: 1 AUXIN has a fixed gain configured by SPI command,and 2 ANAIN/ANAOUT has a fixed gain amplifier with the gain set by two external resistors.ANAIN/ANAOUT can also be used as a microphone differential input ANAIN/ANAOUT becomesMIC+/MIC- in conjunction with an automatic gain control AGC circuit configured by SPI command.Analog outputs are available in three forms: 1 AUXOUT is a single-ended voltage output; 2AUDOUT can be configured as either a single-ended voltage output or a single-ended current output;3 BTL bridge-tied-load is a differential voltage output.
