Digital ChipCorder

Introducing Nuvoton's Digital ChipCorder Series - a cutting-edge line of Voice/Audio chips designed to meet the audio output demands of modern automotive, medical, and industrial applications. These applications require the delivery of crucial pre-recorded information, and Nuvoton's Digital ChipCorder Series is here to make this communication seamless and efficient. The ISD Digital Series, a multi-message ChipCorder, offers several notable features including digital compression, advanced memory management, flash storage, and integrated analog/digital audio signal paths. Message management in this series is specifically designed for simplicity, eliminating the need for addressing and making code development effortless for playback-only applications. This family of chip solutions utilizes flash memory to provide non-volatile audio record/playback ranging from 15 seconds to 16 minutes, all within a single chip. Notably, the ISD Digital ChipCorder series is equipped with an I²S digital audio interface, offering significant improvements from the previous MLS ChipCorder series. These improvements include higher sampling frequencies, enhanced Signal-to-Noise Ratio (SNR), lower power consumption, rapid programming time, and integrated program verification. Requiring no external clock sources or components other than a speaker, the Digital Series delivers high-quality audio prompts and sound effects to improve user interfaces. Additionally, the series offers non-volatile flash storage in 1Kbyte sectors, removing the need for separate serial EEPROM/Flash devices. The ISD Digital Series can handle digital audio data through both I²S and SPI interfaces, and features built-in analog audio inputs, analog audio line drivers, and speaker driver output. In summary, Nuvoton's innovative Digital ChipCorder Series delivers an unparalleled audio solution for automotive, medical, and industrial applications, making it a top choice for developers and manufacturers alike.
