Z520PT is an ultra-low power 32-bit x86 microprocessor introduced by Intel in early 2009 specifically for Mobile Internet Devices (MID). The Z520PT, which is based on the Bonnell microarchitecture (Silverthorne core), is manufactured on a 45 nm process. This processor operates at 1.33 Ghz with a TDP of 2 W. The MPU features a legacy 533 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).

This model is identical to the Z520 model but comes in a larger package and has industrial temperature range support. This processor has a TDP of 2 W when Hyper-Threading is disabled and 2.2 W when enabled.

[Edit/Modify Cache Info]

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory.

The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC.

Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies.

Note: All units are in kibibytes and mebibytes.
