5. Full Device AC operation assumes a minimum of 100 s ramp time from 0 to V
6. Typical values are included for reference only and are not guaranteed or tested. Typical values are measured at V
7. Chip enable (CE) and byte enables (BHE and BLE) need to be tied to CMOS levels to meet the I
8. Tested initially after any design or process changes that may affect these parameters.
