What the Atom Z530P is
The Intel Atom Z530P is a single core Silverthorne handheld processor that Intel launched on March 2, 2009 at 1.6 GHz. It runs one Bonnell core with Hyper-Threading for two threads at 1.6 GHz with no turbo, backed by 512 KB of L2 cache. Power is rated at 2.2 W on a 45 nm process with the SLGPN sSpec.
The P suffix marks the large 22 mm package against the small BGA 441 Z530 at the same clocks. The front side bus runs at 533 MT/s to Poulsbo. Against the Z520PT it adds speed at the same 2.2 W.
Memory is DDR2 single channel through the companion.
Socket and motherboard compatibility
The Atom Z530P is soldered to the board in BGA 437 and cannot be replaced.
The Poulsbo companion pairs over the 533 MT/s bus, so firmware must list the SLGPN sSpec. The CPU cooler compatibility by socket guide covers soldered rules.
Memory, PCIe and cooling
Memory is DDR2 single channel through the Poulsbo companion, fixed per design.
No PCIe comes from the CPU. Expansion and display run through Poulsbo.
Cooling is passive by design for 2.2 W.
Upgrade paths
There is no CPU upgrade path on BGA 437 because the chip is soldered. Keep the Z530P where 1.6 GHz covers the handheld workload.
