Surely it is an oversight but it appears several places.

 

Just downloaded what appears to be the most recent Mega328P data sheet from Microchip. It is a bit strange because it refers ONLY to Mega328P with no reference to M88, or M168. It has a document number of 7810D-AVR-01/15. NB: Errata notes the removal of M88 and M168 from the spec sheet.

 

In the Features list on Page 2, it lists ONLY 32 pin TQFP and 32 pin QFN/MLF

 

In the Ordering Information, it lists ONLY TQFP and QFN.

 

Yet, Mouser says that it has 15,376 of the PU package (28 pin DIP) available to ship.

 

Come on Microchip! Please get your story straight!

 

More importantly: It Matters! DIP users will come to the spec sheet to find the pin-out Without a 28 pin pin-out, the users will need to seek other, and possibly questionable "information".

DIP was removed for PB megaAVR; DIP exists for P megaAVR.

PB megaAVR - 328 is separate as it has functionality that's not in the lesser program space instances.

But that spec sheet is for P, not PB. It is what is on the Microchip web site for M328P.

I wonder why they need to cause so much confusion...if the 328pb has many extras that the 328p doesn't  (extra ports, extra uart, etc)...why not call it a mega329?

The suffix should ONLY be use to indicate package/speed/voltage/temperature ratings, NOT features.

Is the 7810D-AVR-01 / 15 automotive grade?

Many brownie points for kabasan. Though it does not say anything like Automotive Grade on the first page, it refers to Automotive Temperature Range. The title is

 

8-bit AVR Microcontroller with 32K Bytes In-System Programmable Flash

 

That is all. I simply Googled for ATmega328P data sheet and that is what came up. Also, looking at the URL, it is now pretty clear:

 

http://ww1.microchip.com/downloa...

 

But there is next to nothing on the spec sheet that clearly identifies it as such. If you are just offered a link (which Google does), there is very little to tell you what you just got.You have to read fine print to find out that the spec sheet is for an automotive grade device. OK, slightly less bad, but it is still pretty awful documentation. Sorry Microchip, but you can (and should) do a lot better!

 

And, thanks to you who commented.
