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

Probably https://www.silabs.com/mcu/8-bit... ?
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?

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

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.

Time to mark the solution.
