Hello,
I would like some assistance with storing information on a SD card in the format of a text file. This SD card is connected to a 8051 microcontroller. Communication with the card is done via the SPI. I'd really appreciate some sort of #include file or anything that lets me have access to functions such as fprintf and fscanf, fopen, fclose. Also if anyone can tell me weather FATfs (elm-chan.org/.../00index_e.html) files are ok to compile on a 8051.

as an example
SST (now microchip) has some good chips for this. When I needed to find a suitable chip for the then purpose, I actually called SST regarding the chip erase time which for SST is in milliseconds what others want in seconds.
Anyhow the datasheet should tell you all you need to know, BUT be sure you choose a chip you can get. Code for one flash does not necessarily work for another flash.
