Notes

11.Tested initially and after any design or process changes that may affect these parameters.

12.Full device operation requires linear VCC ramp from VDR to VCC(min) > 50 μs or stable at VCC(min) > 50 μs.

13.Device is continuously selected. OE, CE = VIL.

14.WE is HIGH for read cycle.

15.Address valid before or similar to CE transition LOW.
