Mouser Electronics ordered some.

That was in October.  Still not there:

 

Mouser Part #: 556-ATMEGA328PB-AU
Mfr.'s Part #: ATMEGA328PB-AU
Description: ATMEGA328PB 20MHZ IND TEMP
 
Mouser Product Availability

 

No Stock
9,913 On Order

Estimated Ship Date

413 4/5/2017

5,000 5/24/2017

4,500 5/26/2017

Factory Lead Time

10 Weeks

 

 

Can't find any in the wild.

 

A new app needs three USARTs, and we want to stick to AVR8 if possible.  Mega640 is a bit of an overkill. 

 

lol -- just use ATMEGA324PB-XPRO at 30 bucks?  But we need transceivers.  Might be OK for prototype, but we'll roll out a number of these.

 

================================

Is '324PB "real" or not?

I've never met a pig I didn't like, as long as you have some salt and pepper.

Theusch, 

 

take a look at farnell i got my atmega328pb models from there.

 

E: seems to be out-of-stock from there too now....they had plenty couple weeks ago when i ordered mine. now when i see they dont have any in stock im wondering if they allready shipped me some more i did order last week or im waiting for refill :/

 

E: actually you can buy directly from microchip, they have in stock http://www.microchipdirect.com/P...

A backup to a distributor is Microchip.

Lead time appears to vary (Mouser - 10 weeks, Microchip - 15 weeks)

Does the above mean I >>cannot<< purchase in quantities less than 250?

 

Edit:  Apparently.  I tried to add 12 to the cart and not accepted.  Cute trick:  230 available but can only order 250.

Sadly yes, i was allready punching the "buy" button, but you can't even add to the basket quantiny less than 250 :(

Well atleast its not 249 in stock, that would be like someone showing middle finger right at you. Well atleast they have ones with AU suffix "plenty", but where would hobbyist like me get money to buy 250 units, besides i would be spending those rest of my life.

 

E: now when here

Easy enough to try.

Working against resonators, is they tend to have higher CL specs, and many include those CL, meaning you cannot remove them.

Working for a resonator, is their lower Q may mean wider noise pass, and easier startup.

 

You could maybe try this one ?

PRQC16.00SR1010V00L

 

or lowest CL @ 5pF inbuilt

CSTCE16M0V51-R0

 

or if you like thru hole, maybe this one

CSTLS16M0X51-A0

 

 

I can confirm that CSTCE16M0V13L99-R0 resonator is working with 328PB model, maybe bit late answer, but someone might seek for this information in future as i did couple weeks back.

Aand i "lost" 50$ because of this link, was going to order 25 units, but the site told me to use 22$ more for free shipping.

42 units for 50$(free delivery) vs 25 units for 48$(with delivery costs) was not too hard decision even if i never use all of these.

The ones ordered last October, presumably?  And still a month away.

Sheesh -- sorry, folks -- I tacked on Mega324PB questions on the end of the Mega328PB thread.

 

[hmmm--forum search has very little pertinent to '324PB]

No problem

Possibly mega324PB is an alternate in your search.

If a reel is in-stock then there's partial reeling (partial reel price plus nominal fee)

There's no partial tray service.

If no stock then the minimum is multiples of reels or trays.

 

fyi, the automotive mega328PB engineering samples can be quantity one but these aren't available until 2017-Jun-01.

Just to re-iterate: 

 

1)  I've been the primary cause of the confusion. ;) [mixing 328 and 324]

2)  Right now, I am looking for ATmega324PB in TQFP package for a new app.

3)  I cannot find any using Octopart or FindChips or MicrochipDirect. 

3a) A couple "hits" on the above searches indicate that a few flats of -nMU might be floating around.

3b)  The only ones are perhaps in the -XPRO development boards.  While we could work with that for prototype purposes, I am leery of doing the design-in if no real chips arrive with reliable supply.

...

Over the years we have made you aware of important changes we see in the overall semiconductor business environment. This is another one of those times.

...

These challenges are more acute on the products that originated from our Atmel acquisition.

To date, products that originated from core Microchip have fewer challenges.

Atmel originated business has significantly outgrown the capacity plan in place at the time of the acquisition.

Though we have made substantial investment in capacity, the industry wide constraints across the supply chain are providing challenges.
