Introduction
1.1
COM Express™ Concept
COM Express™ is an open industry standard defined specifically for COMs (computer on modules). Its creation makes it possible to smoothly
transition from legacy interfaces to the newest technologies available today. COM Express™ modules are available in following form factors:
•
Mini
84 mm x 55 mm
•
Compact
95 mm x 95 mm
•
Basic
125 mm x 95 mm
•
Extended
155 mm x 110 mm

The SuperSpeed USB ports (USB 3.0) are not in addition to the USB 2.0 ports. Up to 4 of the USB 2.0 ports can support SuperSpeed USB.
The conga-TS370 modules use the Type 6 pinout definition and comply with COM Express 3.0 specification. They are equipped with two high
performance connectors that ensure stable data throughput.
The COM (computer on module) integrates all the core components and is mounted onto an application specific carrier board. COM modules
are legacy-free design (no Super I/O, PS/2 keyboard and mouse) and provide most of the functional requirements for any application. These
functions include, but are not limited to a rich complement of contemporary high bandwidth serial interfaces such as PCI Express, Serial ATA,
USB 2.0, and Gigabit Ethernet. The Type 6 pinout provides the ability to offer PCI Express, Serial ATA, and LPC options thereby expanding
the range of potential peripherals. The robust thermal and mechanical concept, combined with extended power-management capabilities, is
perfectly suited for all applications.
Carrier board designers can use as little or as many of the I/O interfaces as deemed necessary. The carrier board can therefore provide all
the interface connectors required to attach the system to the application specific peripherals. This versatility allows the designer to create a
dense and optimized package, which results in a more reliable product while simplifying system integration. Most importantly, COM Express™
modules are scalable, which means once an application has been created there is the ability to diversify the product range through the use
of different performance class or form factor size modules. Simply unplug one module and replace it with another; no redesign is necessary.
