BGA 1170 socket: CPUs, chipsets and cooler fit
BGA 1170 is the Intel soldered package for Bay Trail-M Celeron notebook SoCs. It carries 1,170 contacts in a 25 × 27 mm footprint and solders directly to the board. Intel shipped the first Bay Trail-M parts in September 2013 at 7.5 W, with 4.5 W dual cores and refreshed clocks following through 2014.

Overview
The package exists for value notebooks where the chipset rides on the processor die. Two or four Silvermont cores with HD Graphics cover web and office work. Memory stays DDR3L-1333 over two channels to 8 GB. PCIe 2.0 with 4 lanes feeds Wi-Fi and storage. Burst clocks lift foreground tabs while efficiency holds battery.
Because the die solders down there is no board choice and no later swap. Notebook makers tune single fan paths for the 4.5 W or 7.5 W class. Buyers pick dual core N2800 parts for kiosks or quad N2900 parts for family multitasking once.
Silvermont was the first Atom generation with out-of-order execution, which lifted per clock speed over Bonnell at similar power. Gen 7 HD Graphics with DirectX 11 support cover notebook video playback and video calls.
Bay Trail-I shares the same 25 by 27 mm BGA 1170 footprint for embedded designs. The Atom E3815 through E3845 launched in October 2013 with one to four Silvermont cores at 5 W to 10 W, ECC memory where boards enable it, and an industrial temperature range down to minus 40 C on listed SKUs. Value notebooks use the Celeron N parts without ECC, while fanless gateways, controllers and digital signs use the Atom E parts with locked lifecycles.
Processor generations
| Codename | Marketing name | Years | Notes |
|---|---|---|---|
| Bay Trail-M | Celeron N2800 and N2900 series | 2013 to 2014 | Silvermont dual and quad core SoCs with HD Graphics, launched from September 2013 for value notebooks at 4.5 W and 7.5 W. |
| Bay Trail-I | Atom E3800 series embedded | 2013 to 2014 | Silvermont embedded SoCs with HD Graphics, ECC memory and industrial temperature range, launched in October 2013 on BGA 1170 at 5 W to 10 W. |
Who BGA 1170 serves
BGA 1170 fits value notebooks, school carts and kiosks where price beats speed. The 4.5 W dual cores suit always on terminals, while the 7.5 W quads cover family browsing with background updates. HD Graphics with burst to 792 MHz plays video smoothly.
Within the family the choice runs from the N2807 at 1.58 GHz to 2.16 GHz through the N2830 and N2840 dual cores to the N2930 and N2940 quads. Clocks and core count decide, since graphics and memory stay in one class. Pick quads where multitasking stutters on dual cores.
Memory and PCIe
Memory support is DDR3L-1333 over two channels to 8 GB with about 21.3 GB/s of bandwidth. Paired SODIMMs help HD Graphics in calls. Eight gigabytes covers school multitasking.
PCIe 2.0 with 4 lanes in one x4 port serves Wi-Fi and SATA SSDs. A 256 GB SATA SSD transforms feel more than clock gaps between refresh SKUs. USB 3.0 and SATA come from the SoC beside PCIe.

Frequently asked questions
Can a BGA 1170 processor be replaced or upgraded?
No. The chip solders with 1,170 balls. A faster notebook or embedded box means a new board or a new machine. Memory on soldered boards also locks at purchase in many designs.
What memory does BGA 1170 use?
DDR3L-1066 in most Celeron N designs and DDR3L-1067 or 1333 in Atom E3800 designs, over one or two channels up to 8 GB. Atom E3800 boards support ECC where the board wiring enables it.
How many PCIe lanes does BGA 1170 provide?
PCIe 2.0 with 4 lanes in a 1x4 split. Notebook and embedded boards wire lanes to Wi-Fi, SSDs and industrial I/O. A SATA SSD matches the power budget without wasting lanes.
What is the difference between Bay Trail-M and Bay Trail-I on BGA 1170?
Bay Trail-M covers Celeron N2800 and N2900 value notebooks without ECC. Bay Trail-I covers Atom E3815 through E3845 embedded parts with ECC, wider temperature range and longer lifecycle. The 25 by 27 mm package is shared.
