Hello all,
I desperately need code for interfacing a Atmel data flash AT45DB081 chip. Does anyone have the code for the particular chip ?

Any help in this regard wil be appriciated

Thanks in advance.

When I started working with Atmel's dataflashes these two documents helped me a lot:

@latecomer
which microcontoller are you planning to use with the dataflash?

best regards

If u are using AVR-Gcc, i recommend you find a AVR-GCC port of the AVR-Butterfly library (please google for yourself). It works for me. As for the electrical interfacing, please note that this chip accepts 5 volts input level (but not for the supply). To interface the output of this chip to ordinary 5 volts logic IC's, simply use a TTL IC like 74LS125. TTLs accepst 3 volts as high.

I'm trying to connect the memory chip to a PIC controller.
Anyoe has any code for the PIC controller ????
My PIC controller has a SPI port.
THanks.

if your micros support both 3 V and 5 V input voltage then there is no problem with interfacing.
you couls direcly connected both input and output your flash IC with micros

see these documents:
http://www.atmel.com/dyn/resources/prod_documents/doc1456.pdf
http://www.atmel.com/dyn/resources/prod_documents/avr335.zip

that code written in C language for AVR, but you can modified it to work with PIC.
