ISD9361 is a Cortex™-M0 based audio SoC providing powerful yet cost effective solution for applications that require voice/audio features. The highly integrated architecture – 32bit Cortex™-M0 processor at 98MHz, 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-function GPIO – was designed to provide cost effective voice/audio SoC solution for consumer and industrial markets. The ISD9361 high compression algorithm achieves more than 50% compression compared to the ADPCM, resulting in memory size reduction while delivering high quality voice/audio. The ISD9361 embedded flash is for user code and audio storage, it can be using with external flash memory for audio storage to extend duration.

Features:

  • ARM® Cortex™-M0 core runs up to 98MHz

  • Deep Power Down (<1µA)

  • 90dB SNR Sigma-Delta ADC with PGA and gain boost stage for
        high quality voice capture

  • Audio PWM speaker driver, 1W at 5.5V 8Ω speaker

  • 16 Analog enabled GPIOs (Port B) allow connection of
         programmable current source for capacitive touch inputs and
         sensor interface
