What is the diff between Vision F v.s. Vision H? for MSP430F5438A

Other Parts Discussed in Thread: MSP430F5438A

Hi all,

I beg your experience：

The same board，the phenomenon is the H version is normal, the F version when first time give power does not work usually, sometimes need the second time power is OK. Customers want to help confirm the two version of what is the difference?

1，First question is what is the H version&F version meaning？Is it right blow...?

or ？？？

2，What is the difference between F and H vision，really exist and how influence？

Thanks a lot！

The phenomenon is the H version of the F version is normal, accidental power does not work, then power on OK. Customers want to help confirm the two version of what is the difference?

    These are specific hardware revisions of the device. As you can see, the revision is typically shown on the package. However, the revision can also be found in the TLV by reading the value at 01A06h in this case (as shown in Table 6-58 above). For Rev H, this value would be 17h.

    All the revision history can be found in the MSP430F5438A Device Erratasheet.

    Dear James,

    Thanks a lot. Very approach. Your answer we have found before, but the key question is the customer has the problem when use this two visions, we want konw whether F & H is different when use in the same environment. I hope it is not our chip`s problem

    by the way, what is the TLV? How to use~

    Thanks!

    According to the first table in the erratasheet, nothing has been changed between these revisions. After comparing the two pictures above, it looks like the board layout has been changed significantly, which could be causing the power issues here. To rule out the hardware, I'd recommend testing both MSP430F5438A revisions using a target development board.

    Hope this helps!

    The device descriptor tag-length-value (TLV) structure contains information about the device ID, die revisions, firmware revisions, and other manufacturer and tool related information. The descriptors contain information about the available peripherals, their subsystems and addresses. As shown in Table 6-58 in the datasheet, you'll see some values listed as "per unit" like the ADC12 Calibration section, for example. Due to slight differences, this calibration data is specific to each device, which ensures accurate performance.

    Here are some links that may provide additional insight.

    Regards,

    James
