ISD9100 Series Datasheet
1 GENERAL DESCRIPTION
The ISD9100 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 ISD9100 embeds a Cortex™-M0 core running up to 49 MHz with 68/100/145K-byte of non-volatile
flash memory and 12K-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 ISD9100 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 16KHz 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 ISD9100 includes a Sigma-Delta ADC with 92dB 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 ISD9100 provides eight analog enabled general purpose IO pins (GPIO). These pins can be
configured to connect to an analog comparator, can be configured as analog current sources or can
be routed to the SDADC for analog conversion. They can also be used as a relaxation oscillator to
perform capacitive touch sensing.
