Notes:
16.This part has a voltage regulator internally; t
POWER
is the time that the power needs to be supplied above V
DD
(minimum) initially, before a read or write operation
can be initiated.
17.t
CHZ
, t
CLZ
,t
OELZ
, and t
OEHZ
are specified with AC test conditions shown in part (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
18.At any given voltage and temperature, t
OEHZ
is less than t
OELZ
and t
CHZ
is less than t
CLZ
to eliminate bus contention between SRAMs when sharing the same
data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed
to achieve High-Z prior to Low-Z under the same system conditions.
19.This parameter is sampled and not 100% tested.
20.Timing reference level is 1.5V when V
DDQ
= 3.3V and is 1.25V when V
DDQ
= 2.5V.
21.Test conditions shown in (a) of AC Test Loads unless otherwise noted.
