Multimessage digital audio recorder

12 November 2008 DSP, Micros & Memory

Nuvoton’s ISD15000 is a single-chip, multimessage, digital ChipCorder series targeted for the automotive, industrial and telecommunications markets. The devices provide audio grade record/playback, digital compression, integrated analog/digital audio signal paths, built-in, comprehensive memory management including macro scripts, I²S digital audio interface, fast digital recording and high sampling frequency.

The device features user-selectable durations from 2 to 32 minutes based on 8 kHz/4-bit ADPCM. Digital audio sampling rate is 48 kHz and data can be recorded at up to 1 Mbps. The device has a built-in message management system, and recording is performed in an address-free manner, so that simple index-based commands can be executed for playback.
