CY7C65213 QFN soldering

mpritchard_2773481 Oct 12, 2017 3:39 PM

Does the square pad on the back side of the QFN package need to be connected to ground?

I'm playing with you design kit and want to ensure I get the design right. . .

Thanks

Recommend to connect to ground. The below apps note has the guidlines of designing QFN package device.

Usually the EPAD of an IC will be connected to GROUND of the PCB board. You could also check the Cadance PCB file if you have installed EZ-Serial SDK.
