MSP430F5528: 1.8V Operation

Jason Taschereau

Part Number: MSP430F5528

Hello,

I'm planning to run my MSP430F5528IYFF at 1.8V AVCC/DVCC, but the datasheet does not give a min/max spec on what the acceptable voltage range would be. I have an LDO that I'm planning to use, but I'd like to make sure its accuracy and line/load regulation will keep the output voltage within spec for the MSP430. Where might I find this information?

Regards,

Jason

The data sheet says that 1.8 V is the minimum, you should design accordingly.

1.8 V is designed for a power supply of 2.0 V ± 10 %.

You can use whatever nominal voltage you like, as long as the actual voltage never goes below 1.8 V.

Hi,

Keith Barkley and Clemens Ladisch are right.

The table 5.3 in the data sheet specifies the voltages that you can apply on VCC.

Best regards,

Andre
