Is Dataflash going obsolete?

Started by aleksa October 3, 2010
Just been to uk.farnell.com to check for
serial flash memory and almost all are
Awaiting Delivery / Out of Stock / No Longer Manufactured.

Is there something else that is supposed to
replace the serial flash or what?

Looks like some big user(s) have ramped up their volume - many of these parts are on factory allocation. Not obsolete - just hard to buy at the moment.

yep - lead times are an order of magnitude worse for some components.

Especially bad for Atmel. But others are easier to get. For example, plenty of stock for this 1Mbit SPI SOIC-8: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=3D91457= 986&uq=3D634218282672489576&cshift_ck=3Dnull&client_id=3D5042 OP: What size and package are you looking for?

16Mbit SOIC-8. Only Atmel (AFAIK) has it in that package. Have no idea why packages of more pins even exist. (there are more *not used* pins than used pins) Schukat also has ALL Atmel dataflashes on allocation... wierd.

SST (now owned by Microchip) do an SOIC-8 16Mbit and 32Mbit

You can extend that to ALL Atmel microcontrollers as well. Blame Apple for hogging all the electronics and Atmel for exiting the fab business.

It's the plain size of the chip. To big for SOIC-8... -- Uwe Bonnes bon@elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------

Now you've got me worried.. I've just learned AT91SAM9260 and... well, Farnell never had it (in TQFP) and Schukat now wants to sell 216 pcs at once. That leaves me with TME only.. As Uwe Bonnes explained the packing issue, I was reading about M25P32.. It is promising, price almost the same, but can't be written on a page basis w/o first erasing a whole sector (!).

Take it while you can. We got three months of Atmel chips when it was last available. Digikey had 3 to 4 thousands and all gone the next day. Should have gone for six months of supply. We won't design with any more Atmel chip until we have a year of supply.
