Intel Atom Z2760 socket: BGA 617

What the Atom Z2760 is

Intel Atom Z2760 is a dual core Cloverview tablet SoC that Intel released in September 2012. It uses the Saltwell core design on a 32 nm process with Hyper-Threading for 4 threads. Clock behavior is 1.8 GHz (no boost). The cache is 1 MB L2 (512 KB per core). Power is 3 W. Graphics come from PowerVR SGX545 (533 MHz).

Saltwell is an in order design with Burst Technology that lifts short clocks for touch response. The SoC integrates a dual channel LPDDR2 controller, PowerVR graphics and tablet I/O on die, which suits small bodies with soldered memory. It is a 32 bit design, so modern 64 bit app support is the binding limit on surviving devices.

At 3 W the Atom Z2760 belongs to the Atom Z phone and tablet group. The clocks suit calls, messaging, reading and video on small displays with passive cooling. Devices pair it with eMMC storage and soldered LPDDR2. The How to find your CPU socket type guide shows how to confirm the package before ordering parts.

Socket and motherboard compatibility

The Atom Z2760 solders to BGA 617 with 617 balls in a 14 by 14 mm FC-MB4760 footprint and cannot be moved to another board. Phone and tablet makers qualify each model with a specific board and Android build, so even another Cloverview part is not a drop in upgrade.

Firmware decides service results more than speed. The board build must list the exact Atom Z2760 string, and Android support stays on older branches for this 32 bit family. The CPU cooler compatibility by socket guide notes that soldered phone parts have no desktop mount pattern. Socket vs chipset: what decides whether a CPU works covers Intel pairing basics.

Memory, PCIe and cooling

Memory support is lpddr2-800, two channels, soldered next to the SoC. The dual channel layout feeds the PowerVR graphics block that shares system RAM. Capacity locks at purchase.

I/O is on device rather than PCIe slots. Storage, wireless, cameras, sensors and touch controllers follow the device wiring, so the maker spec sheet is the final word on ports. USB and display output vary by model, and there is no graphics card slot to consider.

Cooling uses the phone or tablet chassis, fully passive at 3 W. There is no fan curve to adjust and no retail heatsink to fit. Sustained speed follows case temperature, so a warm pocket throttles sooner than a cool desk.

Upgrade paths

There is no CPU upgrade path on soldered BGA 617. The Atom Z2760 cannot be removed, so a faster part means a new board or a new device. Within the family Intel Atom Z2580 shows a Clover Trail Plus option on the same ball count, but phone boards and firmware rarely mix.

A platform move means a new phone or tablet. Current devices use 64 bit SoCs with LPDDR4 or newer memory and current OS support, which no BGA 617 board can reach. Recycle the old device through a proper e waste path once data is wiped.
