Hi, Please see attached image of this QuickRAM chip. It does not state the PN family on the marking as I have seen before. It looks like this is a custom made part for Tandberg. Can I get confirmation that this part does not deviate from form fit or function on the datasheet specifications? Will there be any technical differences that will affect the performance in relation to the standard QL4009-1PF100C?
Thank you in advance!

Sorry for the delayed reply, I would need to check the date code marking to see if we still have record as this device.
It would appear at first glance to have a date code of week 5 2002. The QL4009-1PF100C is a ViaLink device which is one time programmable.
As this has custom marking I would suggest that it has already been programmed and can't be erased.
We have seen a lot of this on the grey market, so we can't guarantee the functionality or reliability of these devices, and I would be careful about purchasing them.

In most cases, custom parts like this are not expected to have technical differences that would impact performance compared to the standard QL4009-1PF100C.mapquest

Maybe some of these suggestions can help you:
1. Verify origin and validity: Since this is likely a custom part for Tandberg and may have been programmed once, verifying the chip's origin is important. Please contact the manufacturer or an authorized QuickLogic dealer directly to confirm the validity of this device.
2. Check the date code and identification marks: Provide complete information about the date code and any other identification marks on the chip to the manufacturer so they can inspect and verify the device. rice purity score
3. Reviews from reputable vendors: Avoid purchasing devices from the gray market as there may be risks to functionality and reliability. Make sure you buy from a reputable supplier or from authorized sources.
4. Comparison with standard specifications: If possible, ask the supplier or manufacturer to provide detailed technical documentation of this custom chip for comparison with the QL4009-1PF100C standard. This will help you identify any differences in form, size, or function.
Wishing you success in verifying and using this device effectively!

My opinion is that the forum post on "QL4009-1PF100C - Part Marking difference" highlights an important issue regarding the differences in how components are marked. This post not only provides useful information about a particular product but also warns of possible risks.
Thank you very much for all your work and this fix, keep up the good work!Robert wrote: ↑Fri Jan 19, 2024 3:33 pm Sorry for the delayed reply, I would need to check the date code marking to see if we still have record as this device.

If the chip was custom-labeled for Tandberg, it may still be a standard QL4009 die relabeled for contractual or inventory reasons.
