Microcontroller Dilema! - Electronic Circuits Projects Diagrams Free

Peace,

Im in a bit of a situation here. Im doing my project and I had been relying on working with AT89C51ED2 microcontroller from Atmel.

Its has 64K ROM with UART. It was very simple to program with the serial port. I used the "Flip" software by ATMEL to downwload the HEX file onto the chip.

Recrently, my last AT89C51ED2 IC got damaged and now I find that the DIP40 package has been discontinued everywhere.

Can some one help me find a suitable substitute (DIP40) for this chip for me please? How would I program this substitute (with which software on the computer)? It also has to have 64K ROM.

Any help appreciated.

Thanks.

Soldering a 44 pin QFP isn't hard. YOu can just drag it with your soldering iron. Are you able to get a SMD-to-40 DIP adaptor? YOu could just solder it on...no guarantees the pinout is going to be the same though unless the DIP adaptor is specially made.

Thanks. Thats really my last option.

Im looking at a 32K ROM device by Phillips called P87C58X2BN
Datasheet: http://docs-europe.electrocomponents...6b8062a0b3.pdf

Can any one please suggest a suitable software that allows the downloading of program code for this microcontroller? Thanks very much.
