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
frequency specification specifies a minimum clock period of 1/f
OP
. Therefore, for every f
OP
clock cycle, t
CLH
+ t
CLL
must be equal to or greater than 1/f
OP
. For example,
if the 2.1MHz period = 476ns and t
CLH
= 190ns, t
CLL
must be 286ns.
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.
