MSP430FR2110: Power supply ripple requirement

Muyan Lin

Part Number: MSP430FR2110

Dear Teams,

Supply power ripple requirement are not mentioned in the datasheet. 3V power supply ripple at 210mV, does it affect chip application?

Hi,

210mV ripple can affect the application. I would suggest you to add a LDO or a big capacitor on the power supply chain.

Best regards,

Hi Cash,

Thanks your reply.

210mV ripple is measured on normal working products. Why would it definitely affect the application? Is there any basis for this?
