Intel Desktop Board D945GSEJT Product Guide

Lead-free 2LI/Pb-free 2LI Board

The electronics industry is transitioning to European Union (EU) Restriction of Hazardous Substances (RoHS)-compliant products. The RoHS legislation restricts the use of six materials. One of these restricted materials is lead. Lead is the most common and problematic of the RoHS restricted materials.

There are exemptions in RoHS that allow the use of lead in some very limited locations in electronic products. Maximum lead concentration values have been established for RoHS-compliant electronic products that allow up to 1000 ppm of lead.

Lead-free/Pb-free is a nickname that is often used (or misused) for RoHS-compliant products. In this case, the term "Lead-free/Pb-free" means that lead has been removed where required by the RoHS legislation but still may exist as an impurity below 1000 ppm.

The term "Lead-free 2LI/Pb-free 2LI" means lead-free second level interconnect (2LI). The balls, leads, or pads used to connect the component to a printed circuit board are lead-free, but the first level interconnect (FLI) is not lead-free. The use of lead in the FLI is acceptable because of the RoHS "flip chip" or "die bump" interconnect exemption.

Intel Desktop Board D945GSEJT is a lead-free second level interconnect product. Table 28 shows the lead-free second level interconnect marks as they appear on the board and accompanying collateral. These marks are based on JEDEC standard J-STD-609, “Marking and Labeling of Components, PCBs and PCBAs to Identify Lead, Lead Free and Other Attributes.”

D945GSEJT specifications

The Intel D945GSEJT is a compact motherboard designed for use in embedded systems and low-power computing applications. Released as part of Intel's 945GSE chipset family, it is equipped with a range of features and technologies that cater to the growing demand for efficient computing solutions.

At the heart of the D945GSEJT is the Intel Atom N270 processor, which operates at a frequency of 1.6 GHz. This processor is known for its low power consumption, making it an excellent choice for devices that require continuous operation without significant energy demands. The D945GSEJT operates with a thermal design power (TDP) of merely 5 watts, allowing it to run quietly and efficiently, thus extending the lifespan of the device.

In terms of memory support, the D945GSEJT features two DIMM slots that can accommodate up to 2 GB of DDR2 SDRAM. This enables adequate multitasking capabilities, allowing the system to run multiple applications simultaneously without performance degradation. Additionally, the motherboard supports a memory speed of 533 MHz and 667 MHz.

One of the key characteristics of the D945GSEJT is its integrated graphics capability, featuring the Intel Graphics Media Accelerator 950. This technology supports resolution up to 2048 x 1536 at 75Hz, making it suitable for basic graphical tasks such as web browsing and video playback. The inclusion of an array of output options like LVDS, VGA, and TV-out enhances its versatility for various display needs.

The D945GSEJT also boasts a variety of I/O ports, including six USB 2.0 ports, a parallel port, a serial port, and multiple audio connectors. This wide array of connectivity options allows users to attach peripherals like printers, keyboards, and external audio devices easily.

Moreover, the motherboard includes support for Intel’s SpeedStep technology, which dynamically adjusts processor voltage and frequency, helping to optimize power consumption based on workload demands. This capability is essential for embedded systems where power efficiency is paramount.

To summarize, the Intel D945GSEJT is a robust motherboard that combines efficient processing power with a compact footprint. Its main features include support for low power consumption via the Atom N270 processor, integrated graphics, adequate memory options, and a wide range of I/O ports. These traits make it an ideal choice for embedded applications, digital signage, and other compact computing environments.
