Function
PWM driver positive output. This SPK+ output, together with SPK-
pin, provide a differential output to drive 8 speaker or buzzer.
During power down this pin is in tri-state.
Or, can be configured as Class-AB BTL which, together with SPK-
pin, provides a differential voltage output.
Or, can be configured as a Class-AB single-ended output.
In PWM mode: Digital Ground for the PWM Driver.
Or,
In Class-AB mode: Analog Ground for the Class-AB output.
PWM driver negative output. This SPK- output, together with SPK+
pin, provides a differential output to drive 8 speaker or buzzer.
During power down this pin is tri-state.
Or, can be configured as Class-AB BTL which, together with SPK+
pin, provides a differential voltage output.
Or, can be configured as a Class-AB single-ended output.
In PWM mode: Digital Power for the PWM Driver. Deliver 0.9-watt
output power at V
Or,
In Class-AB mode: Analog Power for the Class-AB output. Class-AB
BTL delivers 0.7-watt output power at V
Active low interrupt request pin. This pin is an open-drain output.
Can be configured as GPIO3.
An output pin to report the status of data transfer on the SPI
interface. “High” indicates that ISD15D00 is ready to accept new SPI
commands or data.
Can be configured as GPIO2.
Applying power to this pin will reset the chip. (A high pulse of 50ms
or more will reset the chip.)
Serial data output of the external serial flash interface. Connects to
data input (DI) of external serial flash.
Serial data CLK of the external serial flash interface.
Serial data input to external serial flash interface. Connects to data
output (DO) of external flash memory.
Chip Select Bar of the external serial flash interface.
Digital power supply for the external flash memory. A minimum 1uF
capacitor with low ESR<0.5OHM should be connected to this pin for
supply decoupling and stability. Refer to the application diagram.
