Team,

Could you help review the layout showing as below?(Cs:Power supply bypassing cap)

And could also let me know why we suggest tantalum cap?

    Hi, Roy,

    The layout seems to be correct. I didn't find anything that should be modified.

    Regarding the tantalum capacitor recommendation, we basically recommend a capacitor with low derating capacitance. In addition, the tantalum capacitor has a low ESR value, which avoid the voltage dropping at the VDD pin.

    Best regards,
