Socket 370
Celeron processors based on Mendocino core were released in 1998 in SEPP (Slot1) and plastic PGA (Socket 370) packages, but already in 1999 the SEPP package was phased out by Intel in favor of PPGA package. Plastic PGA (socket 370) CPUs were cheaper to manufacture, and moving to new proprietary socket allowed Intel to further separate high-end and budget processor markets. All Celeron processors with Mendocino core were manufactured using 0.25 micron technology and had 128 KB on-chip L2 cache running at full processor speed. The processors in PPGA package were produced at speeds ranging from 300 to 533 MHz, and processors in SEPP package were produced at speeds 300 - 433 MHz.

The first microprocessor based on Mendocino core. This processor is marked as "300A/66", the suffix "A" is used to distinguish it from older Covington Celeron 300/66 CPU. New feature in this Celeron was integrated 128 KB L2 cache running at the processor speed. Addition of the L2 cache was the main reason why the performance of this CPU was much better than performance of older Covington Celerons. Like the older Celeron 266, the Celeron 300A was a very good overclocker. It was possible to run the CPU at 450 MHz by using 100 MHz bus speed.
