Atmel 8051 micro: AT89C51-ED2 in 40 pin DIP package - HELPPPP

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.

Cool. :)

Maybe one of the 89S5x parts will work?

That's allot of flash area, I'm not sure if any of the other 805x
compatibles from Atmel have that much.

What will you do when you run out again? Have you considered switching to
something else? I just recently plunged myself into the ARM world and I'm
loving it. JTAG debugging, GCC gnu toolchain for free, what more could
someone want. If you really must have 40 pin dips, then the AVR line should
suffice. Just say no to 8052. ;-)
