Spent most of the day without any success, researching on Microchip site=20
and back archived emails + web, looking for a possible answer to the=20
following:

What does the  "K" in Microchip part numbers mean for example PIC18F44K20 ?
or
What does the "J" in Microchip part numbers mean for example PIC18F46J50 ?

I just picked these two from a list,thinking that it would help in=20
researching ... but sigh ...


datasheets for reference:
http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=3Den026338
http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=3Den539708

When you go to almost the last page; to section "PRODUCT IDENTIFICATION=20
SYSTEM"
it offers no help.

I found a previous (archived post back in 24/06/2011)post:

[PIC] Figuring out Microchip part numbers?

by HaroldHallikainen  (with reference to different PIC)

...but isn't quite what I'm after... but in a way close.

Having been away from PIC's for some years, Microchips product range has=20
grown drastically.

I don't have a part in mind yet to point this post to, otherwise I would=20
link it here.

I'm hoping there might be a document that explains this, or at least=20
narrows it down a little.

Does anyone know of any documentation of sorts that might explain the=20
PIC part numbers?

else what terms to type in to search for.

Thanks

Peter
