Function
Master-In-Slave-Out. Serial output from the ISD2100 to the host. This
pin is in tri-state when SSB=1.
Can be configured as a general purpose I/O pin.
Serial Clock input to the ISD2100 from the host.
Can be configured as a general purpose input pin.
Slave Select input to the ISD2100 from the host. When SSB is low
device is selected and responds to commands on the SPI interface.
Master-Out-Slave-In. Serial input to the ISD2100 from the host.
Can be configured as a general purpose I/O pin.
Digital Ground.
Digital Power for the PWM Driver.
PWM driver positive output. This SPK+ output, together with SPK- pin,
provide a differential output to drive 8Ω speaker or buzzer. During
power down this pin is in tri-state.
Digital Ground for the PWM Driver.
PWM driver negative output. This SPK- output, together with SPK+
pin, provides a differential output to drive 8Ω speaker or buzzer.
During power down this pin is tri-state.
Digital Power for the PWM Driver.
Active low interrupt request pin. This pin is an open-drain output.
Can be configured as a general purpose I/O pin.
An output pin to report the status of data transfer on the SPI interface.
“High” indicates that ISD2100 is ready to accept new SPI commands
or data.
Can be configured as a general purpose I/O pin.
This pin should be left unconnected.
