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. http://www.8051projects.net/forum-t3048.html 2009-01-07T21:53:45-08:00 Ajay As far as i know, DIP package is very very hard to find rather if you really want it then make use of the PLCC64 package that could be the only option for you as per your problem. But i just searched the famous stockists RS Components and they have the IC AT89C51-ED2-3CSIM in stock!So i think you must hurry to grab them.. do call them once..here is the website..www.rswww.comHope i have solved the problem
