It is obvious that my magnifying glass is not working due to a chip malfunction.I need to find an compatible STA1080ELA3 for it. I have found one, but I am not sure if it is suitable or not. Please help me check it out.<a href=" removed link " target="_blank" rel="noopener"> removed link If you have any channels, please let me know.

@eric12368 You need to provide more info. From what little info you have given, you are looking for a Microprocessor Unit (MPU) of the Cortex variety.

Sorry, due to some recent very bad spamming, until you have a certain number of posts you can't post links. If that continues, do a screen grab of the URL instead and paste it inline. Not sure if that will work, but try.

My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

Hi @eric12368,

  As you may see, your link is not appearing. As Ron (@zander) says, you might try a screen (image) grab, or maybe make it look less like a link ... e.g remove http:// from the beginning.

However, my 5 second Google suggested STA1080ELA3 is a 361 'pin' ball grid array for the automobile industry ... which means it might be tricky to buy in 1-off (at a sensible price), and will certainly be tricky to solder if you are not equipped and experienced with dealing with such devices. Is that what you are expecting?

Best wishes and good luck, Dave

@davee FYI @eric12368 Not sure if we are speaking the same language, but my google shows the STA1080ELA3 to be an ARM Cortex-R4. It is aimed at the auto radio sector to be sure, but I don't see 361 pins. 

Maybe if the OP told us what he is trying to do it would be helpful.

Link is https://estore.st.com/en/sta1080ela3-cpn.html

@davee FYI @eric12368 I did a search on NAPA (auto parts) and got lot's of hits. It appears the MPU is used in all kinds of parts, all expensive. I then tried DIGIKEY and it can be purchased for about $15 USD. It is more like an arduino or Pi, a general purpose Arm Cortex CPU.

Hi Ron @zander,

   Have a closer look at your referenced page .. (ignoring the cartoon chip picture at the top of the page)

https://estore.st.com/en/sta1080ela3-cpn.html

In particular, this snip:

image

Similarly, a chip "flavour" sheet ("flavour" because 13 pages for a processor that runs Linux is not a data sheet!) at

https://html.alldatasheet.net/html-pdf/1009237/STMICROELECTRONICS/STA1080/2267/1/STA1080.html

on Page 10

image

And from your Digi Key ref

image

which, confirms 361 pin LFBGA, and also says 30 week delivery, in minimum tray quantity of 504 for $7.6k.

--------------------------------------------------------

So overall, I have a feeling this thread is going nowhere useful, at the moment.

I was rather hoping the questioner was going to provide a pointer to another chip, perhaps with a similar-ish number, as this one seems a bit OTT for a magnifying glass.

Best wishes,

Dave

@davee Strange, I think we are finding two different devices. I see 16 leads, and the device with 361 is totally different. Also I found a site that had thousands in stock. Cost is about $15 in units of 1. Digikey do NOT stock, they pass the order to the factory who only sell in large quantities.

In any case, until we know what the OP wants it for it's all just a waste of  our time. For all we know he is building a car radio which this device is used for.

Hi Ron @zander,

  Sorry, I don't know where you see 16 leads, but looking on the ST (own store) website:

https://estore.st.com/en/sta1080ela3-cpn.html

which has

image

 at  the top left corner, this is not a package photo, but a fill-in they use when they don't have a photo.

The top of the page looks like

image

but clicking on the data sheet link, just below the 16-leg picture, will download a data sheet, which starts:

image

again confirming 361 lead PGA.

-------------------------------

I only include the above, in the hope it helps in the future, as this isn't the only place I have seen a 16-pin chip picture, that turns out to be BGA or other, 100s of leads device.

---------------------------------------

Also note, although the 'price' is $14.77, it is an 'out-of-stock' part, with no sign of when it will come into stock. I suggest this fits with the Digi-Key 30 week for a tray model ... we are not making any more, unless someone orders at least a trayful, and then we will make to order.

My view, just from previous web searches for chips, is that if a chip is a 'currently available' product, Digikey and Mouser will usually keep a tray of reel in stock ...  probably with some sort of sale-or-return deal with the main manufacturers. This looks like a chip that is effectively obsolete, unless a bulk buyer appears.

--------------------------------------

As for the reason for the question, the thread started with:

It is obvious that my magnifying glass is not working due to a chip malfunction.I need to find an compatible STA1080ELA3 for it.

This is the first magnifying glass I have heard of, that needs a Linux capable processor and car radio audio .... 😏 😏 

Best wishes, Dave

@davee I never heard of the concept of a 'fill-in' photo. Seems dodgy to me. I should have looked at the Mouser site, they have the correct picture. As far as availability, See pic

Hi Ron @zander,

By 'fill-in' photo, all I mean is a default picture on a standardised web page template, that gets overridden when there is an actual product photo to show. (i.e. the webpage will initially be designed as a template, which will be reused 1000s of times, and that picture is just a placeholder.) Not dodgy .. just a practical approach, when Digi-Key didn't have a real chip photo.

-------------------

Take a closer look at your screen clip.

image

That says LFBGA 361, the 361 Ball grid array package ... Not the 36 or so pins shown in the picture!

I see the clip is from Ovaga, that seems to specialise in buying stocks, and reselling them later, presumably for a premium when the chip is otherwise unobtainable, as everything seemed to be 'Request For Quote' for a price.

----------------------------

And when I try Mouser:

image

Much the same story as Digi-Chip ... albeit the picture says "Images are for reference only See Product Specifications ", which is a warning that It might not look like the picture, and at least they found a BGA image.

However, it is out of stock, minimum quantity 504, and 30 weeks as a (nominal) factory lead time.

Best wishes, Dave

@eric12368 Were you joking or serious about the device being for your magnifying glass? The reason I ask is it is an ARM Cortex dual CPU MicroProcessor. It is usually used in car radio systems, it is in the same family of chips as a Raspberry Pi 4b, and Apple iPhones to name two.

I want to make a laser pen by myself. I am looking for electronic chip components suitable for laser pen, some laser chips like SOP23-6.
