Why does Atmel not produce AVR in uSOIC chip packages?

Kind of a broad statement.  So, you want a Mega164 in a 40-pin long-and-skinny vs. 44-lead QFP?  What about Mega64?  That would really be long and skinny.

 

Now, define "uSOIC".  Is that a JEDEC designation?

 

I'd have more interest if you told the reason for this quest, and how many of the design you will produce, and why a design seems to be taking up too much space for the AVR.  And which models in particular--after all, Tiny10 comes in SOT23...is that too narrow or something?

 

I don't know if you'll find any Mega or Xmega in other than "square" QFP or similar.  So you are asking about Tinys?

 

Indeed, many like '2313 come in "20S 20-lead, 0.300" Wide, Plastic Gull Wing Small Outline Package (SOIC)"
 

The short answer to your broad statement is:  Atmel does produce AVRs in uSOIC package.

Tiny441 family: 14S1 14-lead, 0.150" Wide Body, Plastic Gull Wing Small Outline Package (SOIC)

Tiny167 family: 20X 20-lead, 4.4 mm Wide, Plastic Thin Shrink Small Outline Package (TSSOP)
Tiny85 family:

8S2 8-lead, 0.208" Wide, Plastic Gull-Wing Small Outline (EIAJ SOIC)
S8S1 8-lead, 0.150" Wide, Plastic Gull-Wing Small Outline (JEDEC SOIC)

 

Tiny24 family:

14S1 14-lead, 0.150" Wide Body, Plastic Gull Wing Small Outline Package (SOIC)
 

Tiny40:

20X 20-lead, 4.4 mm Body, Plastic Thin Shrink Small Outline Package (TSSOP)
 

Tiny20:

14S1 14-lead, 0.150" Wide Body, Plastic Gull Wing Small Outline Package (SOIC)
14X 14-lead, 4.4 mm Body, Thin Shrink Small Outline Package (TSSOP)

 

Maybe others.  So your whinge might have to do with a particular model?  Product selector on Atmel's site doesn't have this information?

You can put lipstick on a pig, but it is still a pig.

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

and how many of the design you will produce

If it's enough you could probably persuade Atmel to package it in anything you liked. If you ordered a million chips (perhaps more) I bet they'd supply it in a package of your choice (subject to their contract manufacturers facilities) or perhaps as a bondable die so you could make your own packaging arrangements. Generally anything is possible if you offer enough money!

Darn new forum software--must have eaten up all of RES's clarification responses.  Or am I the ultimate troll bait, taking time to search out the information that I posted?

Mini-SOIC or Micro-SOIC[edit]

Another SOIC variant, available only for 8-pins and 10-pins ICs, is the mini-SOIC, also called micro-SOIC. This case is much smaller with a pitch of only 0.5mm. See the following table for the 10-pin model:

I think he must be asking about these half-mm spaced parts. No, I'm not digging through datasheets to find what ones have this pitch. 

If you don't know my whole story, keep your mouth shut.
