Applications

The Intel Mobile Celeron was Intel's value-tier mobile processor line of the early 2000s, designed for budget and mainstream laptops where power efficiency and low heat output mattered as much as raw performance. The 1.13GHz Mobile Celeron in Micro-FCPGA was used in entry-level notebooks from Toshiba, Compaq, IBM, and other OEMs of that era, sitting below the Mobile Pentium III in Intel's lineup but sharing much of the same core architecture. Today these processors are primarily sought as replacement parts for Toshiba Satellite 1105 and similar early-2000s laptops kept in service, as well as by collectors maintaining period-correct machines. The Micro-FCPGA socket was a short-lived mobile-specific packaging standard used by Intel around 2000–2002 before the platform transitioned to Pentium 4-M and Centrino.
