1 Introduction
The Portwell PCOM-B700G, a Type 7 COM Express basic (125mm x 95mm) module is designed with Intel® Xeon® processor
D-1500 product family. Specifically, the COM Express 3.0 specification's Type 7 pinout, when compared to the Type 6 pinout, trades
all the graphics interfaces for up to four 10GbE ports and a total of 32 PCIe lanes, ideal for applications in micro server and the like,
requiring low power consumption while supporting high computing performance and communication throughput. Portwell's
PCOM-B700G features two 10GbE KR, one GbE, DDR4 ECC/non-ECC memory support, and Gen3 PCIe supporting high speed I/O
card. In addition, Portwell's PCOM-B700G Type 7 COM Express module also supports a wide -40°C~85°C industrial temperature
range (selected SKUs).
The new COM Express® Type 7 standard is a new specification with backward compatibility to the existing Type 6 pinout. While the
focus of Type 6 is on display-oriented applications with support for audio and video interfaces, the Type 7 pinout definition is
designed for applications that do not require graphics support. Specifically, the COM Express® 3.0 specification's Type 7 pinout,
when compared to the Type 6 pinout, trades all the graphics interfaces for up to four 10GbE ports, and a total of 32 PCIe lanes. This
makes it ideal for applications in micro server and the like that require low power consumption while supporting high computing
performance and communication throughput.
This latest PCOM-
B700G COM Express® module extends Portwell’s product family of server-grade COM Express® based
platforms. Back in 2015, Portwell launched PCOM-B634VG, a Type 6 COM Express® module, which was the first COM Express®
module featuring Intel® Xeon® processor D-1500 series, 10GbE support, and integrated VGA. Based on PCOM-
B634VG’s success,
Portwell’s new PCOM-B700G Type 7 COM Express® module extends the design from PCOM-B634VG, removes the VGA interface
and adds NC-SI (Network Controller Sideband Interface) as well as more PCIe lanes to meet the COM Express® Type 7 standard.
The two 10GbE-KR ports on PCOM-B700G allow customers to flexibly design their physical interface on a carrier board in several
modes, KR for backplane connectivity, copper (RJ45), or fiber (SFP+). And the NC-SI signals provide a way of connecting BMC
(baseboard management controller) on the carrier board to achieve remote control and management.
