Definition: Pentium M

A family of CPUs from Intel that are part of its Centrino brand for mobile computing. Introduced in 2003 at speeds up to 1.6 GHz, it was formerly code-named Banias. Introduced in 2004, the second-generation Pentium M (code-named Dothan) uses the same chip package but is built with 90 nm circuits rather than 130 nm. Dothan added support for the PCI Express bus, Serial ATA (SATA) and Gigabit Ethernet.

Pentium M supports multiple voltages so that power can be optimized based on user demand. Pentium M predecessors were the Pentium III M and Pentium 4 M.

Banias/Dothan Designations
Whenever Banias and Dothan chip speeds overlap, Intel uses "A" for Banias and "B" for Dothan. For example, Pentium M 1.7A is the Banias chip. See Centrino.
