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.
Stress above those listed under
“
Absolute Maximum Ratings
”
may cause permanent damage
Note 2
:
Typical leakage values are in the 20nA range.
ORG pin may draw >1
μ
A when in x8 mode due to the internal pull-up transistor.
The shortest allowable SK clock period = 1/f
(as shown under the f
parameter). Maximum
SK clock speed (minimum SK period) is determined by the interaction of several AC parameters stated
in the datasheet. Within this SK period, both t
SKH
and t
limits must be observed. Therefore, it is not
allowable to set 1/f
SK
= t
SKHminimum
+ t
SKLminimum
for shorter SK cycle time operation.
Note 5
:
CS (Chip Select) must be brought low (to V
) for an interval of t
in order to reset all internal
device registers (device reset) prior to beginning another opcode cycle. (This is shown in the opcode
diagram on the following page.)
