BGA 592 socket: CPUs, chipsets and cooler fit
BGA 592 is the Intel soldered package for Bay Trail-T Atom tablet SoCs. It carries 592 contacts and solders directly to the tablet board. Intel shipped the first Bay Trail-T parts in September 2013 at about 2 W for thin tablets.

Overview
The package exists for small tablets where power and board area matter more than speed. Four Silvermont cores with HD Graphics cover reading and video at 1200 by 800 on the Z3735G. Memory stays LPDDR3 over a single 32 bit channel to 1 GB. The whole SoC sips power for all day standby.
Because the die solders down there is no upgrade of any kind. Tablet makers tune passive spreading for the 2 W class. Buyers pick storage size once alongside the fixed memory ceiling.
Sibling Z3740 and Z3770 parts share the Bay Trail-T family with wider memory up to 4 GB and panels up to 2560 by 1600 for hybrids that multitask. Those SKUs suit larger tablets with keyboards, while the Z3735G with its 1 GB ceiling stays in small reader slates. All share Silvermont quad cores with HD Graphics on 22 nm.

Who BGA 592 serves
BGA 592 fits small reader tablets and school slates where price and battery beat performance. The Z3735G with its 1 GB ceiling suits single app duty with video playback. Seven inch and eight inch bodies hide the modest specs behind portability.
Within the package the choice is storage size rather than silicon, since one SKU covers this batch. Sibling Z3740 and Z3770 parts with wider memory suit hybrids that multitask.
Memory and PCIe
Memory support is LPDDR3 over one 32 bit channel up to 1 GB with about 5.3 GB/s of bandwidth. The narrow bus caps multitasking, so close background apps on reader tablets. No memory choice exists after purchase.
Board I/O comes from the SoC with USB and storage for tablets. Wireless radios cover connectivity. A microSD slot decides usable storage more than any other feature.

Frequently asked questions
Can a BGA 592 processor be replaced or upgraded?
No. The chip solders to the tablet board. A faster tablet means a new device. Memory size locks with the 1 GB ceiling on this SKU.
What memory does BGA 592 use?
LPDDR3 over a single 32 bit channel up to 1 GB on the Z3735G. The narrow bus and small ceiling suit reader tablets rather than multitasking hybrids.
What display does the Z3735G drive?
Display output up to 1200 by 800 on this SKU. Sibling Bay Trail-T parts reach higher resolutions with wider memory.
What is the difference between BGA 592 and BGA 1170?
BGA 592 with 592 balls carries 2 W Bay Trail-T tablet chips with 1 GB memory ceilings. BGA 1170 with 1,170 balls carries notebook Bay Trail-M Celeron parts with 8 GB ceilings and faster bursts.
Can the memory be upgraded later?
No. The 1 GB of LPDDR3 solders down with the chip, so the storage slot is the only expansion on these tablets.
