GENERAL DESCRIPTION
ISD91500 series is an audio system-on-chip (SoC) integrated with high-quality audio features optimized for low power, audio record and playback. ISD91500 can run up to 49 MHz with embedded ARM® Cortex®-M0 32-bit microcontroller core and 64Kbyte non-volatile flash memory which has additional 6KB boot loader flash and 20K-byte embedded SRAM. ISD91500 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. ISD91500 series 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. Typical applications include USB headsets, Gaming controllers, USB/I2S audio bridge and voice communication systems. 2 FEATURES
