The date the product was first introduced.
Expected Discontinuance is an estimate of when a product will begin the Product Discontinuance process. The Product Discontinuance Notification (PDN), published at the start of the discontinuance process, will include all EOL Key Milestone details. Some business units may communicate EOL timeline details before the PDN is published. Contact your Intel representative for information on EOL timelines and extended life options.
Lithography refers to the semiconductor technology used to manufacture an integrated circuit, and is reported in nanometer (nm), indicative of the size of features built on the semiconductor.
Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements.
MACsec IEEE 802.1 AE
802.1AE is the IEEE MAC Security (MACsec) standard which defines connectionless data confidentiality and integrity for media access independent protocols.
IEEE 1588, also knows as the Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems.
