Seems like another round of missing/no stock ATMEGA328PB TQFP devices (which are NOT the same feature-wise as ATMEGA328P)

 

I saw something about these coming in from Thailand.

 

Why doesn't the 48PB/88PB/168PB have the same feature set as the 328PB (like 5 timers, 10PWMs,  2 uarts, etc)

 

The regular 48/88/168/328 series are all duplicates, except for their memory sizes.

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

Thanks--I should have mentioned TQFP parts...perhaps a QFN to TQFP adapter would work (or solder little wires to extend the pins....arrrrg)!

Interesting...on Thurs nobody (including Mouser) had any TQFP...mouser was saying they'd have some no time soon, with a 20-26 week leadtime

 

On Friday Mouser has 1500 in stock, with more coming (supposedly) at the end of the month!!

Wonder why doesn't the ATMEGA168PB have 5 timers?...would be nice if the 44/88/168/328PB family all had the same features....That has probably been a "surprise" for many when their apps quit working in the smaller chips.

It is a surprise to many I'm sure.

It seems like a mistake to just add a 'B' suffix to those popular devices and give them new features and remove the full swing xtal osc. (to save money), you really don't have self contained 20MHz operation anymore.

They should have been given a new part number to avoid confusion.

Could consider a secondary distributor (EOL, NRND) in-lieu of the manufacturer or a primary distributor :

Wonder if they actually have any, or maybe they are just a "front" to say they might be able to get them ...The chip supply world is murky.

Now THAT is a healthy lead time, eh?

 

You just need to base your app on the -XMINI -- a few hundred of those floating about.

I complained to Atmel/Microchip that no distributor has any...they replied that the reason is, there is no stock!!!

 

I'm not sure if that is their way of promoting a feeling of quick customer responsiveness.

There has probably been a moderate transistor shortage, which has slowed making more of this mega part---each one requires several hundred thousand transistors.

I think there is a secret register you can set to switch the chip from a Mega328P  to Mega328PB....once you know the secret, please tell us.

Maybe a game of Tetris lurks in there as well.

 

quite strange, it has been months and no chips...what are they doing, etching each transistor by hand?

Atmel only responded (weeks ago) to a query saying they were in short supply because they don't have any

Just to make it clear it's two different chips. 

A 328PB can't run 20MHz from a crystal a 328P can!

 

If they have chips or not depends on one of the big buyers/users that allocate a million a month and then one month only buy 900000 there is a tad for us.

Why isn't the mega168PB, just  lower memory version?  Instead it lacks extra timers, dual Uarts, etc

 

This creates a broken family & the problems that come from that.

it has been like that already since around June--WHY???   By November that is almost 1/2 a year!!    

Did they quit making them?  If they can't supply the chip, they should supply a kit of transistors & schematic to make your own replacement.
