BGA 1234 socket: CPUs, chipsets and cooler fit
BGA 1234 is the Intel soldered package for Broadwell-Y Core M tablet and 2 in 1 SoCs. It carries 1,234 contacts in a 30 × 16.5 mm footprint and solders directly to the board. Intel launched the first Core M parts in September 2014 at 4.5 W with configurable bursts.

Overview
The package exists for fanless premium thin devices that need Core performance without vents. Two Broadwell cores with four threads cover office multitasking at 800 MHz to 1.2 GHz base with turbo to 2.9 GHz on top SKUs. HD Graphics 5300 drives high resolution panels. Memory stays LPDDR3 and DDR3L over two channels to 16 GB. PCIe 2.0 with 12 lanes feeds SSDs and radios.
Because the die solders down there is no later swap. Makers tune passive spreading with occasional small fans for the 4.5 W class. Buyers pick 5Y10 parts for battery life or 5Y71 for top turbo once.
The 5Y71 carries vPro eligibility for business detachables with manageability, while the whole line shares HD 5300 graphics and 16 GB memory ceilings. Configurable TDP points let makers tune each SKU between silent 3.5 W profiles and 6 W bursts.

Who BGA 1234 serves
BGA 1234 fits premium 2 in 1 detachables and thin tablets where silent Core performance decides the design. The 4.5 W envelope with 3.5 W SDP points suits sealed bodies. Makers pair it with high DPI displays and SSDs.
Within the family the choice runs from the 5Y10 at 800 MHz to 2.0 GHz for battery life through the 5Y31 and 5Y51 mid tiers to the 5Y70 and 5Y71 at up to 2.9 GHz turbo. Graphics stay HD 5300 across the stack, so base clocks and turbo decide. Pick by burst needs rather than core count, since all use two cores.
Memory and PCIe
Memory support is LPDDR3-1600 and DDR3L-1600 over two channels to 16 GB with up to 25.6 GB/s. Soldered LPDDR3 dominates premium thin bodies. Dual channel fitting feeds HD 5300 in calls.
PCIe 2.0 with 12 lanes in x1, x2 and x4 splits serves SSDs and Wi-Fi. Four lanes to storage cover tablet speeds. The remainder cover radios and sensors.

Frequently asked questions
Can a BGA 1234 processor be replaced or upgraded?
No. The chip solders with 1,234 balls. A faster 2 in 1 means a new device. Memory size locks at purchase on soldered boards.
What memory does BGA 1234 use?
LPDDR3-1600 and DDR3L-1600 over two channels up to 16 GB. Dual channel pairs feed both cores and HD 5300 graphics, so fast LPDDR3 helps video calls.
How many PCIe lanes does BGA 1234 provide?
PCIe 2.0 with 12 lanes in x1, x2 and x4 splits. Thin boards wire lanes to SSDs and radios. A SATA SSD matches most 2 in 1 designs.
What is the difference between BGA 1234 and BGA 1515?
BGA 1234 at 30 × 16.5 mm carries 4.5 W Broadwell-Y Core M parts with HD 5300 graphics from late 2014. BGA 1515 at 20 × 16.5 mm carries 4.5 W Skylake-Y Core m parts with newer HD 515 graphics.
