[Spec. sheet or Data sheet] Intel celeron U1900 Technical data request.

[jiuk_choi]

Hello. world!
I'm jiuk choi, a system engineer working in Korea.
Recently, I was trying to compare the specs of Intel Celeron cpu j1900 and Intel Celeron u1900 . I easily found the technical data of cpu j1900 on intel website But I couldn't find the cpu u1900's technical data on the intel website.
So I inquired using the Intel service email, Intel directed me to this forum site and replied that I should try contacting this forum site.
If anyone has specs or datasheets of Intel Celeron u1900 cpu, please contact or reply me.
thank you.

Hello @jiuk_choi

Thank you for posting on the Intel® communities.

We understand that you have previously opened an internal support case regarding this request about an Intel® Celeron® U1900 Processor. After reviewing your internal support case, we can see that Intel® Customer Support pointed out that this is an Embedded Processor and they referred you to the Embedded Products forums, which is the proper channel of support.

Since this is regarding an Embedded Processor, we have a forum for those specific products and questions so we are moving it to the Embedded Intel Atom® Processors Forum so it can get answered more quickly.

Best regards,

Hello @jiuk_choi ,

Thank you for contacting Intel Embedded Community.

The Intel Celeron cpu J1900 and Intel Celeron U1900 are the same product; so no differences or individual specs or datasheets for each one (you can use same datasheet for both). Additionally just to let you know that this Baytrail platform has reached the End of Interactive Support. 

Best regards,

Thanks for answering my question.

I already know that the J1900 and U1900 are from the same series, as you might have guessed. To be more specific, different reactions are currently occurring when there is a J1900 CPU and a U1900 CPU in the product IPC I purchased, so I am trying to figure out the differences between all types of the two CPUs to solve the problem.
J1900 is normal. U1900 not working with blue screen.

I think it seem to be occured by internal dynamic network bandwith change function is not work properly. J1900 changes 10Mbps to 10kbps freely. U1900 fixed 10kbps and hold several minuts. and
then system blowed up to blue screen.

The problem written above is occurring within the same Chipset driver of Windows 7 32bit OS. Since I can't check the two parts by separating the physical part from the motherboard, I'm checking under the premise that the CPU recognized by the OS is normal. In addition, I am checking the CMOS firmware by confirming that there is no HW change for the IPC main board equipped with two CPUs.

Because of the above problem I was checking, I expected to find a clue from the difference that would help solve the problem between two CPUs that have separate names and also recognized by OS driver keys separately, so I contacted the manufacturer, Intel. Thanks for your reply anyway, but it didn't help to solve my problem. sorry. Please let me know if you have any more thoughts on my problem above.

thank you.

Hello @jiuk_choi ,

Thanks for your additional information; we are sorry we cannot provide further support to your question since again this product (U1900 or J1900) has reached its End Of Life, so even documentation is no longer available.
