ISD9160Fl

ISD9160

Voice/Audio SoC ChipCorder® delivers highly integrated single chip solution ideal for wide range of voice/audio applications in industrial and consumer markets

The ISD9160 is a Cortex M0 based SoC ChipCorder providing a powerful yet cost effective solution for applications that require voice/audio features. The highly integrated architecture – 32bit Cortex M0 processor, wide operating voltage from 2.5 to 5.5V, I2S digital audio interface, 1 watt speaker driver, built-in flash memory, 3V regulator and multi-funtion GPIO – was designed to provide cost effective voice/audio SoC for consumer and industrial markets. The ISD9160 high compression algorithm achieves more than 50% compression compared to the ADPCM, resulting in memory size reduction while delivering high quality voice/audio. The embedded flash is for user code and audio storage. The ISD9160 can be using with external flash memory for audio storage to extend the duration.
