Notes:
16.Timing reference is 1.5V when V
3.3V and is 1.25V when V
2.5V.
17.Test conditions shown in (a) of AC Test Loads unless otherwise noted.
18.This part has a voltage regulator internally; t
power
is the time power needs to be supplied above V
DD
minimum initially, before a Read or Write operation can be
initiated.
19.t
, t
, t
, and t
are specified with AC test conditions shown in (b) of AC Test Loads. Transition is measured ± 200 mV from steady-state voltage.
20.At any given voltage and temperature, t
is less than t
and t
is less than t
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.
21.This parameter is sampled and not 100% tested.
