MSP430FR6922 Hardware revision (TLV)

Other Parts Discussed in Thread: MSP430FR6922

Hi,

I am trying to read out Revision information for MSP430FR6922 from Device descriptor table (info Block).

Hardware revision is coming back as 0x10, whereas I am getting correct Device ID as well as correct info length and CRC length.

Visually on the chip I see Rev A. How do I make sense of 0x10 programmatically?

soon we are going to revision B and at that time I want to read out revision and log it in the factory.

Thanks in advance for getting back to me ASAP as this is of immediate need.

    Hi Atif,

    Hardware revision for Rev. A on FR6922 is 0x10 (think version 1.0). For Rev. B on FR6922 specifically the hardware revision I believe it should be 0x20, but I am double-checking with our team to make sure that is correct. Note that not all msp430 devices will rev. B be 0x20, but for the MSP430FR6922 specifically I believe this is the value.

    I will reply again as soon as I get confirmation for you.

    Regards,
    Katie

    I've now received confirmation that yes, Rev. B should have the value 0x20 for the revision in the TLV on MSP430FR6922. As a note, we are also working to start providing this information in the errata documents, along with the device marking information that we already provide, in order to make this easier (especially for anyone implementing software workarounds for issues affecting particular device revisions).

    I hope that this helps fully answer your question - let us know if there's anything you still aren't sure about.

    Regards,
