I91535AQI is an audio system-on-chip (SoC) integrated with high-quality audio features and microcontroller in single chip. I91535AQI can run up to 49 MHz with embedded ARM®Cortex®-M0 32-bit microcontroller core and 64K-byte flash memory which has additional 6KB boot loader flash and 20KB SRAM. The audio features include microphone input ADC and stereo DAC with headphone ouput driver.

I91535AQI also comes with a wide variety of peripherals, such as Timers, Watchdog Timer (WDT), Peripheral Direct Memory Access (PDMA), Serial interfaces (UART, SPI, I2C and I2S), USB, PWM modulators, GPIO, SDADC, SARADC, DAC and Low Voltage Detector.

I91535AQI supports a rich set of power saving modes including Deep Power Down (DPD) mode drawing less than 2uA. A micro-power 10KHz oscillator enables the device to periodically wake up from deep power down to check other events.
