Intel signals end of 400MHz FSB Centrinos

Intel has formally detailed the demise of the 400MHz frontside bus Pentium M mobile processor. This week it told customers it would no longer supply these chips after 25 November, according to company documents seen by The Register.

The end-of-life announcement also takes in Celeron M processors running over a 400MHz FSB, and Intel's recently introduced lead-free Pentium Ms.

Marked for the chop are the Pentium M 725, 735, 745, 755 and 765 CPUs, in their BGA and PGA packaging variants. Out to will go the Celeron M 350 and 360, again in both BGA and PGA forms, and the ultra-low voltage Celeron M 733. All these products are sold in batches on trays, but the boxed 400MHz FSB Pentium Ms are on their way out too.

The move will still leave Intel with some 400MHz FSB Pentium M products, but all of them are ultra-low voltage, and the chip giant said it would continue to provide support a few of the full-voltage Pentium Ms to its embedded and consumer electronics customers.

Earlier this month, Intel cut the prices of its 533MHz FSB second-generation Centrino - aka 'Sonoma' - bundles to hasten the move from 400MHz FSB parts to the higher bus specification. ®
