Nuvoton’s highly successful Digital ChipCorder series of Voice/Audio chips, enable a new generation of automotive, medical and industrial applications, which typically require more audio output power, to provide users with essential pre-recorded information. 

The ISD Digital series is a multi-message ChipCorder® featuring digital compression, comprehensive memory management, flash storage, 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.  This family utilizes flash memory to provide non-volatile audio record/playback with durations from 15 seconds up to 16 minutes for a single-chip solution.  ISD Digital ChipCorder series provides an I²S digital audio interface, compared to previous MLS ChipCorder series, these devices provide higher sampling frequencies, improved SNR, lower power, fast programming time and integrated program verification.

The Digital Series requires no external clock sources or components except a speaker to deliver quality audio prompts or sound effects to enhance user interfaces. In addition these parts can provide non-volatile flash storage in 1Kbyte sectors eliminating the need for additional serial EEPROM/Flash devices. The ISD Digital series can take digital audio data via I²S or SPI interface.  The series has built-in analog audio inputs, analog audio line driver, and speaker driver output.
