ISD ChipCorder®

Part No.	ISD2130
Datasheet	ISD2100.pdf
Description	The ISD2130 is a digital ChipCorder ® featuring digital compression, comprehensive memory management, flash storage, and integrated digital audio signal paths. This family utilizes flash 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, the ISD2130 provides higher sampling frequency and a higher SNR of 60dB. The ISD2130 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 ISD2130 supported sample rates. The ISD2130 has built-in speaker driver output.

Features	Duration 30 seconds based on 8kHz/4bit ADPCM Audio Management 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. Sample Rate 7 sampling frequencies are available for a given master clock. For example, the sampling frequencies of 4, 5.3, 6.4, 8, 12.8,16 and 32 kHz are available when the device is clocked at 8.192MHz. Compression Algorithms 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. Oscillator Internal oscillator with internal reference: 8.192 MHz with ±1% deviation at room temperature. Output PWM: Class D speaker driver to direct drive an 8Ω speaker or buzzer I/Os SPI interface: MISO, MOSI, SCLK, SSB for commands and digital audio data 6 general purpose I/O pins that share SPI interface. one 8-bit Volume Controls set by SPI command. Operating Voltage: 2.7-3.6V Package: Pb-free 20L-QFN Temperature Options: Commercial: 0 ° C to 50 ° C (die) Industrial: -40 ° C to 85 ° C
