hey guys , just want to consult you all.

im not sure this can be done so tell me ur opinion.

i have an at89c52 , 8K FLASH. i want to attach external mem to it (how many pins to i have to sacrify?)
and i want to program the flash so when it start up , it will receive the real program from my pc using rs232 communication (i use a MAX232 ic) , write the program on the ram and start executing from there...

2nd , is it matter what type of ram? (DRAM/SRAM)?
