Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GPIO2/MISO | bidirectional | Serial output (MISO) from the ISD2360 to the host, tri-state when SSB=1; can be configured as a general purpose I/O pin. |
| 2 | GPIO1/SCLK | input | Serial clock input from the host; can be configured as a general purpose input pin. |
| 3 | SSB | input | Active-low slave select input from the host, with an internal pull-up to Vccd; when low the device responds to SPI commands. |
| 4 | GPIO0/MOSI | bidirectional | Serial input (MOSI) to the ISD2360 from the host; can be configured as a general purpose I/O pin. |
| 5 | VSSD | power_in | Digital ground. |
| 6 | VCC_PWM | power_in | Digital power for the PWM driver, which can come from a separate supply than VCCD (2.4V to 5.5V operating range). |
| 7 | SPK+ | output | PWM driver positive output that with SPK- forms a differential output to drive an 8 ohm speaker or buzzer; tri-state during power down. |
| 8 | VSS_PWM | power_in | Digital ground for the PWM driver. |
| 9 | VSS_PWM | power_in | Digital ground for the PWM driver. |
| 10 | SPK- | output | PWM driver negative output that with SPK+ forms a differential output to drive an 8 ohm speaker or buzzer; tri-state during power down. |
| 11 | VCC_PWM | power_in | Digital power for the PWM driver, which can come from a separate supply than VCCD (2.4V to 5.5V operating range). |
| 12 | NC | unconnected | No connect; this pin should be left unconnected. |
| 13 | GPIO3/INTB | bidirectional | Active-low open-drain interrupt request output; can be configured as a general purpose I/O pin. |
| 14 | GPIO4/RDY/BSYB | bidirectional | Reports SPI data transfer status, high meaning ready to accept new SPI commands or data; can be configured as a general purpose I/O pin. |
| 15 | VCCD | power_in | Digital power, which can come from a separate supply than VCCD_PWM (2.4V to 5.5V operating range). |
| 16 | XCLK | bidirectional | Labelled XCLK on the SOP-16 drawing; the datasheet's application diagram shows GPIO5/XCLK, and GPIO5 is a general purpose I/O pin. |
