The header says LPC2138. Strange to first select a controller and then try to figure out what to do with it!

Opps, your are right. The data sheet from: http://www.nxp.com/pip/LPC2132FBD64.html shows that this part does not have an external buss or a USB port. So the only uption is MMC/SD cards. The LPC2138 has 256K of flash, should be enough room to put an fat16 file system, if the OP wants it. Xarion, what is it you want do ? donald
