Note: The specifications are subject to change without notice. Verify with your local Intel sales office that
you have the latest datasheet before finalizing a design.
Warning: Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage.
These are stress ratings only. Operation beyond the “Operating Conditions” is not recommended
and extended exposure beyond the “Operating Conditions” may affect device reliability.

† When in the 1-x input clock mode, CLKIN is an input to an internal phase-locked loop and must maintain a
minimum frequency of 8 MHz for proper processor operation. However, in the 1-x mode, CLKIN may still
be stopped when the processor is in a reset condition. When CLKIN is stopped, the specified RESET low
time must be provided once CLKIN restarts and has stabilized.
