DS90UB928QEVM: Updating the User's Manual

Makoto Yoshida

Part Number: DS90UB928QEVM

I got DS90UB927 and DS90UB928 evaluation boards two months ago.

Since the DS90UB927 evaluation board was the same as the circuit described in the user's manual, I was able to turn on the power and check the operation of register access.

But, DS90UB928 evaluation board clearly differed from the schematic in the user's manual in terms of power supply inputs, connector reference numbers, etc.

I contacted TI Support. and told me to wait for a documentation update as the evaluation board I got was up to date.

After one week, no documentation has been uploaded, so I contacted TI Support and he advised me to use this forum.

I'm hoping to get a good response.

Howdy Makoto,

This is the latest User Manual for that EVM. Can you please confirm this is the one you are using?

Thanks,

Holly Roper

Dear Holly Roper

Thank you for your answer. This manual has already been downloaded. Here are pictures of the two evaluation boards I bought.

Top: DS90UB928EVM
Bottom: DS90UB927EVM

DS90UB927EVM(Bottom) board has banana connector contacts for power supply.
But DS90UB928EVM doesn't have that. This is different from the DS90UB928EMV board schematic in the user's manual you provided.

TI Support told me that DS90UB928EVM board I got was the latest revised model. They said that there was no user's manual for this. He advised me to use this forum.

Thank you.

Hi,

Can you please send a high-resolution photo of your EVM? I would like to see the pin labels and the label printed on the IC. The photo from the website is blurry.

Best,

Holly
