The ISD9300 embeds a Cortex™-M0 core running up to 98 MHz with 68/100/145K-byte of non-volatile flash memory and 16K-byte of embedded SRAM. It also comes equipped with a variety of peripheral devices, such as Timers, Watchdog Timer (WDT), Real-time Clock (RTC), Peripheral Direct Memory 2 2 Access (PDMA), a variety of serial interfaces (UART, SPI/SSP, I C, I S), PWM modulators, GPIO, Analog Comparator, Low Voltage Detector and Brown-out detector. The ISD9300 comes equipped with a rich set of power saving modes including a Deep Power Down (DPD) mode drawing less than 1A. A micro-power 16 KHz oscillator can periodically wake up the device from deep power down to check for other events. A Standby Power Down (SPD) mode can maintain a real time clock function at less than 10A. For audio functionality the ISD9300 includes a Sigma-Delta ADC with 90dB SNR performance coupled with a Programmable Gain Amplifier (PGA) capable of a maximum gain of 61dB to enable direct connection of a microphone. Audio output is provided by a Differential Class D amplifier (DPWM) that can deliver 1W 1 of power to an 8Ω speaker. The ISD9300 provides 16 analog enabled general purpose IO pins (GPIO). These pins can be configured to connect to an analog comparator, or can be configured as analog current sources. They can also be used as a relaxation oscillator to perform capacitive touch sensing. 8 of these 16 pins can be routed to the SDADC for analog to digital conversion. 1 We suggest implementing thermal protection by utilizing the Temperature Alarm; for details please refer to Temperature Alarm in Design Guide. -3- Release Date: Oct 23, 2014 Revision V1.1 ISD9300 Datasheet 2 FEATURES  Core – ARM® Cortex™-M0 core runs up to 98.304MHz. – One 24-bit System tick timer for operating system support. – Supports a variety of low power sleep and power down modes. – Single-cycle 32-bit hardware multiplier. – NVIC (Nested Vector Interrupt Controller) for 32 interrupt inputs, each with 4-levels of priority. – Serial Wire Debug (SWD) support with 2 watchpoints/4 breakpoints.  Power Management – Wide operating voltage range from 2.4V to 5.5V. – Power management Unit (PMU) providing four levels of power control. – Deep Power Down (DPD) mode with sub micro-amp leakage (
