True, you must write exactly 264 bytes to the Flash array at a time. But the chip has two 264-byte RAM buffers so it is possible to modify part of a 264-byte page without having to move data out of the chip and back in (read to RAM, change some bytes in RAM, write back to Flash). I've just looked over the data sheet and it looks like a nice part. Strangely though they don't mention anything about endurance. > don't know what the availability is. How available is the 4M part? Has anyone bought one? _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
