ISD3900FYI Product Details
1 GENERAL DESCRIPTION The ISD3900 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 ISD3900 utilizes winbond 25X/25Q series flash memory to provide non-volatile audio record/playback for a two-chip solution. Unlike other ChipCorder series, the ISD3900 provides an I's digital audio interface, faster digtal recording, higher sampling frequency, and a signal path with SNR equivalent to 12bit resolution.
The ISD3900 can take digital audio data via l'S or SPI interface. When I'S 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 ISD3900 supported sample rates.
The ISD3900 has built-in analog audio inputs, analog audio line driver, and speaker driver output The two analog audio inputs to the device are:(1) AUXIN has a fxed gain configured by SPI command, and(2) ANAINANAOUT 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 becomes MIC+/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 volitage output;(2)
AUDOUT can be configured as either a single-ended voltage output or a single-ended current output;
(3) BTL(bridge-tied-load) is a diferential voltage output
· Extemal Memory. support winbond 25X/25Q SpiFlash.
o The addressing ability of ISD3900 is up to 128Mbit1, which is 64-minute recording time based on 8kHz/4bit ADPCM.
· Fast Digital Programming o Programming rate can go up to 1Mbits/second mainly limited by the flash memory write rate.
· Message Management o Perform address-free recording: The ISD3900 allocates memory for new recording requests and upon completion, returns a start address to the host via SPI interface o Store pre-recorded audio(Voice Prompts) using high quality digital compression o Use a simple index based command for playback oExecute pre-programmed macro scripts(Voice Macros) designed to control the configuration of the device and play back Voice Prompts sequences and message recordings.
Sample Rate oSeven record and playback sampling frequencies are available for a given master sample rate. For example, the record and playback sampling frequencies of 4,5.3,6.4,8,12.8,16
and 32kHz are available when the device is clocked at a 32kHz master sample rate.
o For I'S operation,32,44.1 and 48kHz master sample rates are available with record and Cplayback sampling frequencies scaling accordingly.
· Compression Algorithms
o For recording
· ADPCM:2,3,4or 5 bits per sample
· u-Law:6,7 or 8 bits per sample
