  • Forum Post: msp 2274 svs output

    mes
    Hi, Does anyone know of a circuit that could let the SVS output pin (I'm on the 2274) engage a separate power source (like a 9v), until the line-power is restored. Looking to keep cost and complexity low. Br Matt

    Mike at Work
    Nice write-up. Just adding some observations here, FWIW: It is suspected brown-out issues on the 'F135 that prompted me to look into flash protection strategies, as discussed here: http://e2e.ti.com/forums/t/8600.aspx . The 'F135 (which has no BOR) requires that Vcc rise/fall times be faster...

  • Forum Post: F54xx: Using or not using the SVS/SVM modules?

    Johannes Schweidler
    In my efforts to reduce the current consumption of my F5419 based system, I came across the SVS/SVMs. The datasheet says, that each of these modules needs 200nA when turned on, so turning all 4 off would give a benefit of 0.8µA. Which is quite a lot... Unfortunately, if you turn all off, there...

    Shungo
    Hi everyone, I want to information about MSP430F551x/552x SVS/SVM over recommended ranges of supply voltage and operation free-air temperature. This is written in MSP430F543x/541x datasheet (slas612a.pdf) p.53 "PMM, SVS High Side" and more. But it is not written in MSP430F551x/552x...

    Jens-Michael Gross
    sanb SVSMLCTL &= ~(SVSLE|SVMLE); I think it's not the best idea to disable the low-side SVS by clearing SVSLE. This will prevent a device reset if the internal (low-side) voltage falls below the threshold, leaving the processor running on instable working condition. Disabling the SVM is okay...

  • Forum Post: SVS with DAC1 on an MSP340F2617 (errata SVS2)

    Nuwanda
    Hi. I have been using for a few months a device with a 2617 microcontroller (rev. F) that has the SVS always on (configured at 2.2 V + PORON) and sometimes uses DAC1 with digital values ranging from 0 to 1500 (Vcc = 2.5 V, so 1500 would be about 0.92 V). I have just seen in the Erratasheet (SLAZ033H...

    Saran Kiyabu
    After looking through the CC430 errata sheet, I think I found the problem. However, I don't understand what the workaround is telling me to do. The errata sheet is available at http://www.ti.com/lit/er/slaz052i/slaz052i.pdf and the one that I think is troubling me is the following: PMM15 Power...

    I suggest the following challenge: 1) to achieve reliable power-down 64 byte save to the flash memory using the standard Launchpad 2) to achieve reliable power-down 64 byte save on a slightly modified Launchpad 3) to achieve reliable power-down 64 byte with another processor in the family...

  • Forum Post: x5xx_x6xx SVS/SVM question

    Gergely Olah
    Hi, There is something that I don't understand in connection with the PMM of the MSP430x5xx and x6xx series. The SLAU208K document says: "If DV CC falls below the SVM H level, SVMHIFG (SVMH interrupt flag) is set.", and it means that the output of the SVM H block (check Figure 2-5....
