Atmel AT89C51ED2 in 40 pin DIP package

I volunteer with a hobby group on weekends teaching kidfs simple TTL concepts as well as a little programming ... to try to encourage them to enter technology related careers.

We need to find some Atmel AT89C51-ED2-3CSIM (or 3CSUM) chips for some projects. Atmel stopped making them and we can't find them anywhere.

We really want that part because ... its a 51 family part and we're used to it, its a DIP package and we can use cheap wire wrap sockets, it has 64 KB program space in FLASH, 2KB RAM, 2 KB EEPROM ...

Does anyone know where we might find some ... we tried all the big sellers (Mouser, DigiKey, JDR, ...........) no one has any left.

Any help would be appreciated.

Use 89S52/3. That's what I did. Costs less too.

S51/52? Could work if the smaller memory space isn't a problem.

shows that Mouser has some of the PLCC flavor (looks like 44 pin) and there are, albeit not cheap, PLCC-44 wirewrap sockets out there. JDR has some listed, although not in stock.

There are a few others in Atmel's line that have 64K but all seem to be PLCC or denser.

Alternately, the OP probably should dive into the chip list at

to match availability with features and form-factor. There are a bunch of alternate suppliers for the family (Silicon Labs and ST come to mind) who may have something that would work.

Just wanted to update ... I received good news from Atmel this evening. They are coming out with a new component, more advanced then the AT89C51ED2 - and it will be offered in a 40 pin package.

You may see details at ...
