BD-Z7MB-7Z020-G and AES-Z7MB-7Z020-SOM-G/REV-F

Hi there,

The first part number does not sound like a modern part number, maybe an older one?  Can you tell me where you saw that part number?  That might help me track this down.

Thanks, Dan!

We are running out of the 2nd part and it is back-ordered (2022?). So I found the first part on EBay. From the photos, it appears that both are the same. I thought AVNET tech people would know? Appreciated!

Hi there,

If this is for production, I would suggest NOT buying the one from eBay.  There is a lot of risk in that.

The boards are backordered due to parts shortages.  I would have to see how far away, but January 2022 does sound plausible.

From what I could determine, that was an original number way back when (7+ years ago!).

To answer your questions:

• If you do decide to buy that anyway, the electrical footprint should match.
• I cannot say that EVERY aspect of modern software will work.  It should be pretty good/close, but I couldn't tell you for certain it would be fine due to the many revisions MicroZed has had.

I can tell you to be VERY VERY cautious.  There have been many revisions of the board and there are some that while are PIN compatible are not electrically compatible.  There were some revisions to correct issues over time and it is possible that this board would electrically damage another designed for a different revision.  Remember that this was one of the first Zynq boards out there and thus had a learning curve as the Zynq part was flushed out!

If you decide to proceed, ensure you get the exact revision and check all the errata / PCN / etc. that are all posted on the product page.

We do not provide any warranty for parts that have been purchased through eBay - although at the age of this board, that is certainly up anyway.  I would also ask about warranty and see if you can get some sort of guarantee on the IO functionality.  The IO's are VERY robust and I have seen boards where someone was not handling them properly and ESD killed a few IO - while the rest of the chip functioned perfectly fine.

The best course I can recommend is follow up with your local FAE.  They can help guide you to the fastest way to get your hands on an official board.

Good luck!

Thanks, Dan, again! I will hold on then.

I suspect 28nm and older nodes were used for the chips in Microzed boards. One-year back-order is very hard for everyone. Hope AVNET can do better!

Hi there,

Thank you for the encouragement!  We certainly do not want to hold boards back.  The backlog started when Xilinx announced a delay on MPSoC parts.  We put a few actions into play that allowed us to better compensate for that.  From there, we were a little surprised when we found out about the SoC parts.  They ended up with almost a 2x backlog compared to the MPSoC. While the SoC is the longest lead, it is not the only part that we are seeing longer leads.  I think it is a matter of capacity and trying to refill the pipelines that were depleted due to the shutdowns.

We are certainly doing the best we can and communication and forecasting with your local sales team will help us the most.  We certainly do not want to be out of stock. 

Also, please note, we do sell in a first come first serve manor.  If you have not placed your order, I would do so soon in order to get in the queue.

Regarding availability, I think the Zynq-7000 devices are driving the SOM lead-times. You can see the Xilinx lead-times by trying to purchase a part, and you'll get the same story regardless of which distributor you look at. For example, the C-grade device on the MicroZed 7010 is here, looking at 52 weeks.

However, Avnet is trying to aggressively monitor orders and predict demand, which is always an imperfect game to play, but we are trying. I responded to similar issues in a couple other posts:

Re: Availability MicroZed 7020

Given the multiple sizes and temp grades in each family, some will be coming available sooner than others, but all of them are being built. I expect an order placed now would likely be shipped before the end of the summer. However, the very best advice is that you work with your local Avnet FAE, get an order placed, and then they should be able to determine an estimated delivery date.

Hi, Bryan,

I tried to place an order for AES-Z7MB-7Z020-SOM-G/REV-H on the AVNET web site. I tried many times today, and even talked to your 800 help desk. Even the AVNET agent had the same issue:

Every time I used checkout to buy the part, it always says: Error:There is an invalid order item ID. I could not continue from there. I logged out, logged back in, many times; nothing helped.

I understand it is a long wait to receive the parts, but I need to place the order ASAP so I can get them sooner.

HELP?

I have sent an urgent message to our production team to see if they can locate the issue in our system. I apologize for the trouble!

Normally, I would recommend that you call your local Avnet field office and deal with someone local. However, in this case, I expect they will run into the same problem. Hopefully we can find the issue and correct it quickly.

Bryan

Thanks! Please send us an alert once the problem has been solved. Appreciated!

Hi, I just tried again to order. Your web site gave me the some error and would not allow me to proceed to check out. Help?
