ISD9300 Datasheet
1 GENERAL DESCRIPTION
The ISD9300 is a system-on-chip product optimized for low power, audio record and playback with an
embedded ARM® Cortex™-M0 32-bit microcontroller core.
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
Access (PDMA), a variety of serial interfaces (UART, SPI/SSP, I²C, I²S), 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 1W¹ 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.
