We are redoing an 87C51FB design with the 87C51MC2, which is readilly available from DigiKey. The problem is, the -MC2 is an OTP part, and we have a lot of code development to do yet. This is going to kill off a lot of parts before the coding is finished. So, we identified a FLASH part for this, the AT89C51RE2SLSUM, a PLCC44 part, which should do the job nicely.
BUT, after a week of fruitless search, the -RE2 is proving nearly impossible to find. Even Atmel won't supply samples, they refer us to DigiKey. DKey doesn't have any, and they require a minimum order of hundreds, as does everyone else who doesn't have them in stock. We found one distributor who would sell us just two for a premium price, but they're stock is in Hong Kong, so charge $200 shipping! Another distributor will supply two or three, but they won't have any until mid-July!
So I come here in the hopes someone can either suggest a known source with stock in the US or who can sell us a couple out of their stock, right here, right now. We will pay a premium, of course, within reason.
Thanks for your attention, kenjj
Dear Kenjj,
Who is the distributor in Hong Kong of AT89C51RE2-SLSUM in stock? Thanks,
Lidio
Sorry, I can't say. I'm at home today and all the contact info is not at hand. Besides, I tossed all the previous search paperwork almost two weeks ago, which includes that info. The web searches I did found a couple of sites with thousands in stock.
I remember I contacted AERI.com (RFQ), and Arrow Electronics at (408) 453-1200. I have a note on my calender at work to call a salesmen in mid-July about a shipment they were expecting of these. He claimed (two weeks ago) they had 374 left to sell after deducting orders already placed. Just now I've tried a couple of Google searches and perused the Atmel distributor's info, and nothing jogs my memory that way. I'm back at work Sunday, and will try to find references to the search info. How many are you looking for?
Sorry I can't help just now. kenjj
Thanks for your reply.We are needing 250 units. After developing a new product during 3 years, we realize it was a bad choice component. We had some dificulties with AT89C51RE2-SLSUM it is true but we thought it would be resolved in time by ATMEL.
but we thought it would be resolved in time by ATMEL. the sad story is that you are the umpteenth that has thought so about Arghmel.
When they did me in long ago I decided for good never to use an Arghmel chip.
Erik
