1 Introduction
1.1 Description
The ETX-BT is based on the latest Intel Atom® processor E3800 SoC series, adopting the
latest 22nm process technology with 3-D Tri-Gate transistors featuring significant
improvements in computational performance and energy efficiency. The E3800 SOC
series integrates processor- and GPU cores and all I/O on a single chip. Processor
performance is scalable from a single-core Intel Atom® processor E3815 at 1.4GHz to a
quad-core Intel Atom® processor E3845 at 1.9GHz. Two quad-core Intel® Celeron®
processors, based on the same microarchitecture, are also available.
The module supports a single SODIMM for up to 8GB of DDR3L system memory and
comes with integrated support for high resolution VGA and single/dual channel LVDS.
Optionally, a third display can be connected through an onboard flat cable connector. The
ETX-BT's graphics core supporting two independent displays easily outperforms earlier
ETX module generations. Being a drop in replacement for older ETX modules, the ETX-BT
fully supports all typical legacy interfaces of the ETX form factor such as: up to two PATA
IDE with Master only, ISA-bus, PCI-bus, serial/parallel ports and Intel based 10/100Mbps
LAN. As a way to migrate away from legacy PATA flash devices, the module offers an
optional soldered SATA-based SSD with a capacity of 2 to 64 GB.
