Intel has planned to launch a brand-new platform of UMPC which codenamed ?McCaslin?, while the processor ?Stealey?. Though still adopting the 90-nm manufacturing, the total space occupied is tremendously reduced to 14mmx19mm, and 78% of the space is free when compared to the previous models. The microarchitecture will still base on Pentium M, and the clock rate will be 600MHz and 800Mhz respectively. The whole system will be electricity-saving with the 512 KB L2 Cache and the additional mode of Deep Sleep Support (C4).

McCaslin adopts the north bridge codenamed Little River, which occupied a space of 22mmx22mm, and approximately 34% of space is freed when compared to the previous model. Little River also supports 400MHz FSB and DDR-2 400 memory modules up to 1GB. In addition, Little River contains Intel GMA X3000 and supports the DirectX 9.0c, as well as achieves Vista Premium. On the other side, the south bridge adopts ICH 7U which is the simplified version of ICH7-M. ICH 7U supports 8 groups of USB 2.0 ports, occupied space is 15mmx15mm, and around 77% space is saved.
