1.3.1. Technical Details
The EUROCOM 450 is a Intel® Core 2 Duo T7400 or L7400 based single board computer on a COM Express board for
compact industrial real-time systems. The board is based on the Intel chip set E7520 (Lindenhurst) for server systems,
which is on Intel’s Embedded Program for long-lifetime products. The COM module contains all of a CPU’s logic, user-
specific I/O can be implemented on an easytodo carrier board.
1.3.1.1. CPU
A Intel® Core 2 Duo processor is supported; Intel® Core 2 Duo is the successor of the Core Duo CPU. CPU clocks
between 1.5 and 2.16 GHz are supported. The CPU has FPU, MMU, first level cache (32kB each for instruction and data)
and a L2 cache (4 MB unified) on the chip. Each of the two cores contains dual integer units, that can operate in parallel
for certain instructions. Special care has been taken to achieve a low power consumption and a good relationship
between clock and computing performance: the new CPUs do not increase clock speeds whole sacrificing power
consumption; instead, they use a parallel implementation with relatively low consumption. The second-level cache, due
to its location in the CPU itself, runs with the full CPU clock.

The low power consumption of the CPU makes it possible to build systems withstanding high ambient
temperatures with simple cooling.
1.3.1.2. Memory Configuration
The 64-bit wide memory allows configurations of up to 4 GBytes with DDR2-400 RAMs in two DIMM modules, error
detection and single-bit error correction is supported. The DIMMs must be registered and must support ECC.
1.3.1.3. Chip Set
The chip set, an Intel E7520, contains the DDR2 RAM memory controller with ECC, the interrupt controller, three 8-lane
(x8) PCI Express ports and the PCI host bridge for 32-bit/33-MHz PCI, as well as for PCI-X. Additionally, it has logic to
access an 8-bit ROM, it has timers, a DMA controller, and it generates clocks.
