Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

SUSPEND TIMING CHARACTERISTICS
Parameters are 100% production tested at T
A
= +25°C, and guaranteed by correlation over temperature.
Design guaranteed by bench testing. Limits are not production tested.
At V
L
= 1.71V to 2.5V, derate all of the SPI timing characteristics by 50%. Not production tested.
The minimum period is derived from SPI timing parameters.
Time-to-exit suspend is dependent on the crystal used.
