2.1
CPU
The LEC-BTS product family offers three versions of the Intel Atom E3800 Series CPU: the
E3805 (dual core), the E3815 (Single Core), the E3826 (Dual Core), the E3845 (Quad Core),
and the N2807 (Celeron Dual Core). E3800 CPUs feature the Intel 64 Architecture and are man-
ufactured based on Intel’s 22-nanometer technology. Refer to the CPU data sheet at the Intel
web site.
2.2
Memory
The LEC-BTS employs one channel of 64-bit DDR3L on-board memory. Four SDRAM memory
chips provide up to 16Gb of low voltage non-ECC, unbuffered system memory. Refer to the
SDRAM data sheet at the Micron web site.
2.3
I210 LAN Controller
The Intel I210 provides a single-port controller that supports GbE functionality using the
high-speed PCIe standard, v2.1 (2.5GT/s). The I210 features an integrated PHY, which enables
1000BASE-T implementations such as rack-mounted or pedestal servers in add-on NIC or
LAN-on-Motherboard (LOM) designs. Other implementations include blade servers such as
LOMs or mezzanine cards as well as embedded applications such as switch add-on cards and
network appliances. Refer to the Intel I210 Ethernet Controller data sheet at the Intel web site.
