On the Cypress website it says the CYW20719 has 17 GPIOs but on their datasheet on page 18-20 they list 38 available GPIOS.

• 16 GPIOs on QFN package
• 40 GPIOs on WLCSP package

The EVK we sell and support within the SDK uses the QFN package.

As you can see in the datasheet, some GPIOs share the same pin in the QFN package. There are 16 GPIOs avaliable for the QFN package.

The WLCSP package has 40 GPIOs avaliable from P0 to P39.
