Linux-ready COMs offer full range of Intel Haswell CPUs

Sep 5, 2013 — by Eric Brown — 1129 views

Congatec announced two Linux-ready Type 6 COM Express computer-on-modules based on Intel’s 4th Generation Core (“Haswell”) processors. The more compact Conga-TC87 supports Intel’s higher-integration, lower-power embedded processors, while the larger Conga-TS87 offers more PCI Express lanes and USB 3.0 ports, and higher performance graphics including PEG compatibility.

Congatec unveiled the larger “Basic” sized (3.75 x 4.92-inch) Conga-TS87 back in June, shortly after Intel’s 4th Generation “Haswell” Core processors were unveiled. The 22nm Haswell generation averages about 15 percent faster than “Ivy Bridge” Core processors, according to Intel, and features as much as 50 percent lower power consumption.

The Conga-TS87 was introduced with support for only one processor: the quad-core Intel Core i7-4700EQ. Now, in conjunction with announcing the smaller “Compact” sized (3.74 x 3.74-inch) Conga-TC87 COM Express module, Congatec has expanded the Conga-TS87’s processor options to include four dual-core processors, including Core i5 and i3 models such as the Core i3-4100E (25W TDP).

Architecturally, the new Conga-TC87 differs from the -TS87 in that it is designed with Intel’s embedded-oriented 4th-Generation processors chips, which employ single-component (processor+chipset) Haswell models instead of the standard dual-component parts used on the Conga-TS87, as seen in the two modules’ photos and block diagrams.

Whereas the processors supported by the Conga-TS87 range in TDP (Thermal Design Power) from 25 to 47 Watts, using Intel’s optimized Scenario Design Power (SDP) metrics, the -TC87 supports three dual-core, 15 Watt processors the Core i7-465OU, i5-4300U, and i3-4010U.

In addition to having lower TDPs, the Conga-TC87’s processors also offer less advanced Intel HD Graphics. The Conga-TS87’s processors are the only ones to provide advanced video support including MPEG-2 decoding, and support for WMV9 (VC-1), H.264 (AVC) and 40 MBit/s Blu-ray.

Both the Conga-TS87 and -TC87 support up to 16GB of DDR3 RAM. They offer a gigabit Ethernet controller, and support for either seven (TS87) or four (TC87) PCI Express (PCIe) interfaces. Other I/O available via the COM Express Type 6 interface includes four SATA ports, and unlike most Haswell-based COM Express modules, dual ExpressCard interfaces. Additional I/O includes LPC, I2C, eight USB 2.0 ports, and either four (TS87) or two (TC87) USB 3.0 ports.

The two modules also differ on their display support. The Conga-TS87 provides a CRT interface, a PEG (PCI Express Graphics) interface for driving an external high performance graphics controller, and three DisplayPorts. In contrast, the Conga-TC87 lacks CRT and PEG support, but offers an LVDS interface, and also supplies three ports that can either be configured as DisplayPort or HDMI.
