Table 9. Power Down and Power-Up AC Parameters
Note: 1. Some data may be written to any address location if t
EHWH
is less than the minimum required time.
2. The device has to enter and exit Power Down mode after t
CHCL
.
3. The Input Transition Time used in AC measurements is 5ns.
Figure 18. Standby Mode Entry AC Waveforms, After Read or Write
Note: Both t
EHGH
and t
EHWH
define the earliest entry timing for Stand-by mode. If either of timing is not satisfied, it takes the t
AVAX
(min) period
from either the last address transition of A0, A1 and A2, or E1 rising edge.
