So I was considering a 16K SRAM (128x128 = 16K). Does anyone have any suggestions?? Would this be easy enough to implement? Ie connect my 4bit adc on port A, read the whole thing and write it parallel via port B to an SRAM.. that should take less than my 5 allowed instructions =) I hope!! unless the SRAM is really complicated.. but I hope not.. I only really know of SRAM and DRAM, but I know that DRAM will not do the trick =) No chance to refresh anything here! Consider using an SX? More MIPS available (roughly 50 versus 5), DRAM might even be useable.
