BGA 1526 socket: CPUs, chipsets and cooler fit
BGA 1526 is Intel ball grid array package for Ice Lake mobile processors of the Y and U families. The package carries 1,526 contacts in a 50 × 25 mm footprint and solders directly to the device mainboard. Intel lists the package as FCBGA1526 in its specification pages, with a 100 C junction limit.

Overview
The package serves 9 W fanless tablets and 2-in-1 detachables with Sunny Cove cores and Iris Plus graphics, plus the late 15 W Pentium 6805 from October 2020 for slightly larger passively cooled bodies. Core counts stay at 2 cores with Hyper-Threading for the Pentium line, while Core i3, i5 and i7 Y parts scale to 4 cores.
Memory is DDR4-3200 or soldered LPDDR4-3733 in two channels. PCIe runs at version 3.0 for NVMe storage. Because the chip is soldered, the processor, memory size and graphics tier are fixed when the device ships.
Processor generations
| Codename | Marketing name | Years | Notes |
|---|---|---|---|
| Ice Lake-Y | 10th Gen Ice Lake Y | 2019 to 2020 | Ultra mobile processors with Sunny Cove cores and Iris Plus graphics, launched in 2019 with 9 W parts and extended by the 15 W Pentium 6805 in October 2020 on BGA 1526. |
| Ice Lake-U | 10th Gen Ice Lake U | 2019 | Thin laptop processors with Sunny Cove cores and Iris Plus or UHD graphics, launched in August 2019 with 1005G1 through 1065G7 at 15 W, plus the 28 W 1068G7, on BGA 1526. |
Who BGA 1526 serves
BGA 1526 processors belong in fanless detachables where silence and battery life beat sustained speed: 2-in-1 tablets, thin convertibles and education devices with passive cooling. The 9 to 15 W envelope allows sealed bodies without vents.
Within Ice Lake-Y the choice runs from the 2-core Pentium 6805 for classroom and kiosk use to 4-core Core i5 and i7 Y parts for premium detachables. Iris Plus graphics with 32 to 64 execution units cover touch displays and 4K video. Buyers who edit video or compile code should step up to Ice Lake-U on BGA 1526 class U packages with active cooling instead.
Memory and PCIe
Memory support covers DDR4-3200 modules and soldered LPDDR4-3733, with up to 64 GB in two channels on the Pentium 6805. Bandwidth peaks near 51.2 GB per sec with DDR4-3200 pairs. Most shipping devices solder 4 or 8 GB for cost reasons, so the order time choice matters.
PCIe arrives as version 3.0 for a single NVMe SSD plus board devices. Detachables typically wire x4 to 128 or 256 GB of NVMe storage. There is no Thunderbolt requirement on Y designs, so external graphics depend on USB-C DisplayPort rather than PCIe expansion.
Identifying and servicing BGA 1526
Identification in Intel documents reads Sockets Supported FCBGA1526. That line separates BGA 1526 from BGA 1044 Apple Y parts and from BGA 1528 Comet Lake-U thin laptop parts. The LGA, PGA and BGA: CPU package types explained guide explains soldered package trade offs.
Service means whole device service. There is no cooler to swap and no memory slot on most bodies. Battery replacement through the maker extends life once the cells wear. The How to find your CPU socket type guide shows where maker specs list the package.

Frequently asked questions
Can a BGA 1526 processor be replaced or upgraded?
No. The processor is soldered to the board. Upgrading means replacing the board or the whole device, so choose memory size at order time.
What is the difference between BGA 1526 and BGA 1528?
BGA 1526 serves 9 to 15 W Ice Lake-Y detachables with Iris Plus graphics. BGA 1528 serves 15 W Comet Lake-U thin laptops with UHD Graphics. The two packages do not interchange.
Does BGA 1526 use DDR4 or LPDDR?
Boards use DDR4-3200 or soldered LPDDR4-3733, depending on the design. Two channels carry up to 64 GB on the Pentium 6805.
What PCIe does BGA 1526 provide?
PCIe 3.0 from the CPU for NVMe storage and board devices. Exact lane wiring follows the device design, so check the maker specifications for SSD speed.
