 Question:
I would like to have an example on how I in the smartest way interface fast (12-15ns)
1MBit SRAM:s (64 bit wide, 8 IC:s) to the C8x. How shall I set up the AS,PS,CT and BS
inputs. How shall I handle the memory CS input, (gate address and CAS signal?). Are all
CAS signals going low at the same time when you access a 64 bit wide bus?. :
Answer: Use the following
control signals for this SRAM interface: BS = 11 ; R/W PS= 0111 ; R/W AS =000 ; R/W CE/ =
CAS/ ; R/W CT=101 ; Use User Timing for reads CT=110 ; Use User timing for writes W/ =
RAS/ |
