ISD9160FI

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

The I9160FI 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 2.4 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 I9160FI 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 I9160FI can be using with external flash memory for audio storage to extend the duration.
