The ISD2100 is a digital ChipCorder
management, flash storage, and integrated digital audio signal paths.
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, this device provides higher sampling frequency and a signal path
with SNR equivalent to 12-bit resolution.
The ISD2100 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 ISD2100 supported sample rates.
The ISD2100 has built-in speaker driver output.

GENERAL DESCRIPTION
30 seconds based on 8kHz/4bit ADPCM (ISD2130)
Store pre-recorded audio (Voice Prompts) using high quality digital compression
Use a simple index based command for playback
Execute pre-programmed macro scripts (Voice Macros) designed to control the configuration
of the device and play back Voice Prompts sequences.
7 sampling frequencies such as 4, 5.3, 6.4, 8, 12.8, 16 and 32 kHz are available.
µ-Law: 6, 7 or 8 bits per sample
Differential µ-Law: 6, 7 or 8 bits per sample
PCM: 8, 10 or 12 bits per sample
Enhanced ADPCM: 2, 3, 4 or 5 bits per sample
Variable-bit-rate optimized compression. This allows best possible compression given a
metric of SNR and background noise levels.
Internal oscillator with internal reference: with ±1% deviation at room temperature.
PWM: Class D speaker driver to direct drive an 8Ω speaker or buzzer
SPI interface: MISO, MOSI, SCLK, SSB for commands and digital audio data
6 general purpose I/O pins that share SPI interface.
Industrial: -40°C to 85°C
