* Intel® Pentium® III Processors

The Pentium® III processor is ideal for high performance applied computing. It supports highend communications, transaction terminal, and industrial automation applications. While incorporating new features and improvements, the Pentium III processor remains software compatible with previous members of the Intel microprocessor family.The Pentium III processor is validated with multiple chipsets for maximum flexibility and scalability. Combined with the Intel 840 chipset, the Pentium III processor provides high performance and bandwidth including dual processing and a second PCI bus. The 815, 815E, 810 and 440BX chipsets provide a scalable platform supporting a wide selection of Celeron® and Pentium III processors ranging from 66 to 133 MHz processor side bus speeds. The 440BX AGPset supports ECC for the highest data integrity and ISA for legacy I/O. The Intel 815, 815E and 810 chipsets utilize Intel Graphics Technology, an integrated graphics platform which provides more stability, higher quality graphics and a reduced OEM bill of materials cost.Download Product Brief Product Highlights1.26 GHz 370-pin FC-PGA2 package with 512 KB Advanced Transfer Cache (on-die, full-speed L2 cache)1 GHz, 866, 850, 733, 700 and 600 MHz, 370-pin FC-PGA package700, 500 and 400 MHz BGA2 package1 GHz, 866 and 733 MHz processor supports 133 MHz processor side bus256 Kbytes Advanced Transfer Cache (on-die, full-speed L2 cache)Compatible with Intel® 840, 815, 815E, 810E2, 810 chipsets; Intel® 82801E C-ICH; Intel® 440BX AGPset and 440MX chipsetPentium® III processorsProduct Number Core Speed (MHz) L2 Cache External Bus Speed (MHz) Thermal Design Power (Max) Voltage Tjunction PackageRK80530KZ012512 1.26 GHz 512K 133 29.5W 1.45V 69C* 370FC-PGA2RB80526PZ001256 1 GHz 256K 133 29.0W 1.75V 75C 370FC-PGA RB80526PY001256+ 1 GHz 256K 100 29.0W 1.75V 75C 370FC-PGARB80526PZ866256 866 256K 133 26.1W 1.75V 80C 370FC-PGARB80526PY850256 850 256K 100 25.7W 1.75V 80C 370FC-PGARB80526PZ733256 733 256K 133 22.8W 1.75V 80C 370FC-PGARB80526PY700256 700 256K 100 21.9W 1.75V 80C 370FC-PGARB80526PY600256 600 256K 100 19.6W 1.75V 82C 370FC-PGA* Tcase, not Tjunction+ For existing embedded applications using the Intel® 440BX chipset only.
