MSP430FR2311: LMP4.5 behavior in this MCU

Part Number: MSP430FR2311
Other Parts Discussed in Thread: MSP430FR5733

Hi, TI MCU Professional.

Our customer is developing a MCU sysytem.

They use LPM4.5 mode to decrease system current.

No Errata about LPM4.5 but sometimes MSP430FR2311 never react GPIO signal and never wake-up from LPM4.5.

We found an errata PORT19 in MSP430FR5733.  MSP430FR2311 also react same as PORT19, that never get interrupt from GPIO in LPM4.5.

We think this phenomena in FR2311 is same as FR5733 PORT19.

Have MSP430FR2311 same Errata Port19 as FR5733?

B.R.

  • Hi Massa1,

    Do you observe this behavior on a single pin or all pins that are able to wake from interrupt?

    Which pin(s) do you observe this on?

    I will also look further into this with the team.

    Best,

    Owen
