i am using t89c51rd2 chip with flash memory. the program i use has large array allocation. i think it exceeds the internal memory of this chip. i use xternal memory also..but not helping. help me in programming this. shud i go for a higher memory version of the chip..is it available..or is there ne other option. thank u in advance
i use xternal memory also..but not helping. Since you do not specify what you mean by "memory" (Data memory (!RD, !WR) or program memory (!PSEN) I can only guess you are using external data memory. In that case, what do you set AUXR1 to? shud i go for a higher memory version of the chip..is it available..or is there ne other option. I do no see why as you have external memory attached. There is anither option, in the Philips P89C66x series you get up to 8k of XRAM thank u in advance Oh, well, I'll answer although you thank micro. Erik
