TIMING WAVEFORM OF READ CYCLE NO. 1(5,6)
TIMING WAVEFORM OF READ CYCLE NO. 2 (CS CONTROLLED)(5,7)
Notes:
5.WE is HIGH for READ cycle.
6.CS and OE are LOW for READ cycle.
7.ADDRESS must be valid prior to, or concident with, CS transition
LOW, tAA must still be met.
Document # SRAM105 REV A
8. Transition is measured ±200 mV from steady state voltage
prior to change, with loading as specified in Figure 1.
9. Read Cycle Time is measured from the last valid address to
the first transitioning address.
