What is the differences between driver 25C080.c and 25080.c

What is the differences between the driver 25C080.c and 25080.c? My 3.155 compiler only came with the 25C080.c driver and I want to interface to an Atmel AT25080 EEPROM. Will the 25C080.c driver talk to the Atmel chip? Can anyone supply me with the 25080.c driver?

The chips are likely the same, but to check for sure, you have to
download the data sheets at the Microchip and Atmel websites
and compare the timing diagrams, the timing tables, and the
command set, etc. That would take a few minutes to do and
since it's your project, it's probably best for you to do it.

I did that already. The two chips look very similar. I want to make sure I didn't over look something. That was why I was asking if someone who had both files could compare the difference or supply me the file so I could compare the difference. If it is only the file name then I know I have nothing to worry about.

The files are _extremely_ different. However they may well function the same. Both refer to the 25C080, in their header. The only way to be sure, is to work through the data sheet, and look at what the files actually do. The biggest difference is that 25080, reads the status of the chip to time the transactions, while the 'C' version does not.
