Template:mpu Z515 is an ultra-low power 32-bit x86 microprocessor introduced by Intel in early 2009 specifically for Mobile Internet Devices (MID). The Z515, which is based on the Bonnell microarchitecture (Silverthorne core), is manufactured on a 45 nm process. This processor operates at 1.5 GHz with a TDP of just 650 mW and an average power of 160 mW. The MPU features a legacy 400 MT/s front-side bus capable of communicating with the Poulsbo chipset in both low-power CMOS mode as well as normal GTL mode (which also works with other chipsets).
