'''Z540''' is an ultra-low power {{arch|32}} [[x86]] microprocessor introduced by [[Intel]] in early 2008 specifically for Mobile Internet Devices (MID). The Z540, which is based on the {{intel|Bonnell|l=arch}} microarchitecture ({{intel|Silverthorne|l=core}} core), is manufactured on a [[45 nm process]]. This processor operates at 1.86 Ghz with a TDP of 2.4 W and an average power of 220 mW. The MPU features a legacy 533 MT/s [[front-side bus]] capable of communicating with the {{intel|Poulsbo|l=chipset}} chipset in both low-power [[CMOS]] mode as well as normal [[GTL]] mode (which also works with other chipsets).

This processor has a TDP of 2.4 W when {{intel|Hyper-Threading}} is disabled and 2.64 W when enabled.
