Can anyone help me identify this device. It looks like a QFN32 package labeled SILAB F541 ACL09F 1715+. I have looked at the Silabs site but I can't find anything there to match it. I believe it's an 8 bit uC. I need to locate the data sheet.

 

Thanks

I thought that too, but the data sheet for it says that the case marking includes the "8051" or "8051F541". I realize that package markings can vary, so I was hoping that someone might recognize it. Thanks Wes.

You realise that SiLabs have their own forums?

 

That'll be the place where all the SiLabs experts hang out - they are the ones that are most likely to recognise this chip!

Many manufacturers (for example Microchip) have a document that describes their across-the-range package marking. Don't SiLabs have anything like this then?

But that wouldn't fit on the package. What makes you think that it's not a C8051F541?

#1 Hardware Problem? https://www.avrfreaks.net/forum/...

#2 Hardware Problem? Read AVR042.

#3 All grounds are not created equal

#4 Have you proved your chip is running at xxMHz?

#5 "If you think you need floating point to solve the problem then you don't understand the problem. If you really do need floating point then you have a problem you do not understand."

Does it?  Where?

 

But, again: if you have queries about SiLabs documentation then you really need to take that up with SiLabs !

Indeed they do:

https://www.silabs.com/community/mcu/8-bit/knowledge-base.entry.html/2010/03/24/chip_revisions_andd-Z9ha

 

 

 

The OP's is QFN-32, which is 5x5.  So:

 

SILAB
F541
ACL09F
1715+

 

F541

Revision A

Trace code CL09F

Made 2017, week of April 9th

Lead-free

 

 

From the datasheet:

https://www.silabs.com/documents/public/data-sheets/C8051F54x.pdf

 

 

So the order code for the OP's QFN-32 chip is C8051F541-IM.

See why I thought someone here would know?

Thanks.

I didn't.  In fact, personally I've never laid eyes on a Silicon Labs device.  I just spent about 3 minutes with Google.  You could have done the same! ;-)

 

Happy to help, though.
