It's better to be connected to GND(VSSD). That will help cooling the chip.We can refer hardware design of CY8CKIT-043 and CY8CKIT-044.Thanks,Ryan View solution in original post 0 Likes Reply All forum topics Previous Topic Next Topic 1 Reply Re: Should the exposed tab on QFN-68 CY8C4245LTI-M445 be connected to GND?
