ISD15D00 DATASHEET
1 GENERAL DESCRIPTION
The ISD15D00 is a digital ChipCorder® featuring digital compression, comprehensive memory
management, and integrated analog/digital audio signal paths. The ISD15D00 utilizes serial flash
memory to provide non-volatile audio playback for a two-chip solution. The ISD15D00 provides an I2S
digital audio interface, faster digital programming, higher sampling frequency, and a signal path with
SNR 80dB.
The ISD15D00 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 ISD15D00 supported sample rates.
The ISD15D00 has inbuilt analog audio inputs, analog audio line driver, and speaker driver output.
The analog audio input, Aux-in, has a fixed gain configured by SPI command. Aux-in can directly
feed-through to the analog outputs; it can also mix with the DAC output and then feed-through to the
analog outputs.
Analog outputs are available in two forms: (1) Aux-out is an analog single-ended voltage output; (2)
Class-AB BTL (bridge-tied-load) is an analog differential voltage output. Class-AB BTL delivers 0.7-
watt output power at VCCSPK = 4.5V.
Class-D PWM direct-drive is also available, which delivers 0.9-watt output power at VCCSPK = 4.5V.

o The addressing ability of ISD15D00 is up to 128Mbit, which is 64-minute playback time based
on 8kHz/4bit ADPCM.
o Inbuilt 3V voltage regulator to provide power source to the external flash memory
Fast Digital Programming
o Programming rate can go up to 1Mbits/second mainly limited by the flash memory write rate.
Memory Management
o Store pre-recorded audio (Voice Prompts) using high quality digital compression
o Use a simple index-based command for playback
o Execute pre-programmed macro scripts (Voice Macros) designed to control the configuration
of the device and play back Voice Prompts sequences.
Sample Rate
o Seven sampling frequencies are available for a given master sample rate. For example, the
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 I2S operation, 32, 44.1 and 48kHz master sample rates are available with playback
sampling frequencies scaling accordingly.
Compression Algorithms
o For Pre-Recorded Voice Prompts
µ-Law: 6, 7 or 8 bits per sample
