On the left hand side are analog circuitry and connectors for recording and playback:
PWM (O) is a direct speaker drive. In ISD15100, it can also be configured as:
•
•
•
•
•
•
•
•
Internal oscillator with external resistor:
Crystal:
AUDOUT (J): Can be configured as either current-type or voltage-type single-ended output.
AUXOUT (K): Voltage-type single-ended output.
MICIN/ANAIN (L): Can be configured as either differential or single-ended input.
AUXIN (N): Voltage-type single-ended input.
Voltage-type differential output (BTL).
Separately configure SPK+/SPK- as AUDOUT/AUXOUT.

Put jumper J12 on 2-3.
Users can change the external resistor for different sampling rate.
Put jumper J12 on 1-2.
Users can change the crystal for different sampling rate.
When configured as voltage-type output, it is exactly the same as AUXOUT.
Users need an external amplifier to drive the speaker.
Install jumpers (M) 3-4, 7-8, and 11-12 for differential input (MICIN).
Install jumpers (M) 1-2, 5-6, and 9-10 for single-ended input (ANAIN).
Please note that we use a general I/O pin to “physically” enable/disable the
microphone. Later when users hook up their own microcontroller to command the
ISD15100, they can either:
BTL can directly drive the speaker, but then the volume level won’t be as loud as
PWM. Users can attach an external amplifier for a loud volume.
Manually enable the microphone by installing the jumper on J8 (this will
increase standby current), or
Use an I/O pin to “physically” enable/disable the microphone as the EV board
does.
