kieran Posted March 30, 2003 Report Posted March 30, 2003 Hi Everybody,I ordered some memory chips from Microchip. I have some standard 24LC256, as suggested by the Bankstick parameters. However, I also ordered some 24LC512 Â chips.Can the 24LC512 be used instead of the 24LC256? If so, can the Midibox or MIOS handle the full EEPROM space (512k) available to the 24LC512, allowing for a greater data storage capacity over the 24LC256 (256k) model?The clock speed is the same between the two models, the only difference is the greater capacity, 512k for 24LC512 http://www.microchip.com/download/lit/pline/memory/pnp/21754a.pdf and 256k for the 24LC256 http://www.microchip.com/download/lit/pline/memory/ic/21203j.pdf. :Dbest regards,Kieran.

TK. Posted March 31, 2003 Report Posted March 31, 2003 Hi Kieran,yes, the 512k(bit) == 64kbyte derivative should also work and MIOS allows to access the upper address page. But there is no application yet which allocates more than 32kBest Regards, Thorsten.
