Stefan, its really only the 1769-byte XRAM limitation of my current Atmel AT89C51RD2 that is holding me back. Any additional enhancements beyond the more expansive XDATA space may be a plus, provided drop-in pin compatibility with the RD2 was not compromised. Well your suggestion of incorporating some serial ram got me thinking, Stefan. The RD2 seems to have hardware SPI functionality that might be used for this purpose, but the interfacing job may be a little too fiddly for those, which it is intended. Hi Murray, I think Stefan was referring to serial SPI RAM like what was suggested in a previous thread, where capacities up to 32KByte (or even greater for FRAM, apparently) available? http://www.8052.com/forum/read/172187 Cheers, Valentin |
