ISD9300 Series 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 1A. 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 8speaker.
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.

ISD9300 Series 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 (<1µA).
Wakeup from Deep Power Down via dedicated WAKEUP pin or timed operation from internal
low power 16KHz oscillator.
Standby mode with limited RAM retention and RTC operation (<10µA).
Wakeup from Standby can be from any GPIO interrupt, RTC or BOD.
Sleep mode with minimal dynamic power consumption.
3V LDO for operation of external 3V devices such as serial flash.
Flash EPROM Memory
68/100/145K bytes Flash EPROM for program code and data storage.
Pre-fetch and mini-cache for near zero-wait state memory access.
4KB of flash can be configured as boot sector for ISP loader.
Support In-system program (ISP) and In-circuit program (ICP) application code update
1K byte page erase for flash
Configurable boundary to delineate code and data flash.
Support 2 wire In-circuit Programming (ICP) update from SWD ICE interface
Pre-fetch and cache for near zero-wait state memory operation.
SRAM Memory
16K bytes embedded SRAM.
Clock Control
One high speed and two low speed oscillators providing flexible selection for different
applications. No external components necessary.
Built-in trimmable oscillator with range of 16-50MHz. Factory trimmed within 1% to settings of
98.304MHz. User trimmable with in-built frequency measurement block (OSCFM) using
reference clock of 32kHz crystal or external reference source.
Ultra-low power (<1uA) 16kHz oscillator for watchdog and wakeup from power-down or sleep
operation.
External 32kHz crystal input for RTC function and low power system operation.
GPIO
Four I/O modes:
Quasi bi-direction
Push-Pull output
Open-Drain output
Input only with high impendence
TTL/Schmitt trigger input selectable.
I/O pin can be configured as interrupt source with edge/level setting.
Switchable pull-up.
Audio Analog to Digital converter
Sigma Delta ADC with configurable decimation filter and 16 bit output.
90dB Signal-to-Noise (SNR) performance.
