Note 5:
Stress above those listed under
“
Absolute Maximum Ratings
”
may cause permanent damage to the device. This is a stress rating only, and functional operation of the device
at these or any other conditions above those indicated in the operational sections of the specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
Note 6:
The f
OP
frequency specification specifies a minimum clock period of 1/f
. Therefore, for every f
clock cycle, t
+ t
must be equal to or greater than 1/f
OP
. For
example, for a f
OP
of 1MHz, the period equals 1000ns. In this case if t
CLH
= is set to 410ns, then t
CLL
must be set to a minimum of 590ns.
Note 7:
/CS must be brought high for a minimum of t
CSH
between consecutive instruction cycles.
Note 8:
This parameter is periodically sampled and not 100% tested.
