congatec further standardises interface setup for SMARC 2.0

 

congatec has introduced a SMARC 2.0 module supporting powerful USB-C connectivity. The utilisation of the USB-C specification makes USB interconnects even more universally applicable, further standardising the interface setup of SMARC 2.0-based embedded devices.

System designers can use USB-C for standard peripherals from USB 3.1 to USB 1.0 and - a new option - for connecting displays or even the power supply to the system or peripheral devices, reducing cabling efforts to a single cable. In addition, the current data throughput of up to 5Gbs in line with the USB 3.1 specification serves as a turbo charger for data intensive applications. Based on Intel Atom, Celeron or Pentium processors (codename Apollo Lake), typical applications for SMARC 2.0 designs are handhelds and other mobile devices, in-vehicle devices and stationary embedded and IoT systems with low power and high performance demands.

By introducing this universally applicable form of plug and play functionality, congatec greatly simplifies the use of embedded technology. Fully featured USB-C jacks are still rare and present a real breakthrough for standardising the fragmented world of cable-based external interconnects. Such standardisation is very beneficial for system engineers as well as system integrators, administrators and device users. System engineers don't need to think about the interface setup anymore. They only need to specify the number of USB-C compliant peripherals they want to interconnect and design in USB-C interfaces accordingly. And system integrators can plug their USB-C compliant peripherals in any USB jack available on the board and it works. Now, doesn't that sound fantastic? We know that we are only at the beginning of this evolution and that 100% availability of fully featured USB-C jacks is still a vision today but imagine how easy system specifications will become once this transition is complete?, explained Martin Danzer, Director of Product Management at congatec.

The application ready best practice design-in of recent USB-C capabilities is shown on congatec's SMARC 2.0 modules with latest Intel Atom, Celeron and Pentium processors and a suitable carrier board with one fully featured onboard USB-C jack for demonstrating the new power supply capabilities as well as the display integration.

The feature set in detail
congatec initially implements USB-C on its new conga-SA5 SMARC 2.0 Computer-on-Module and the new evaluation carrier board conga-SEVAL. The comprehensive USB-C functionalities include USB 2.0, USB 3.1 Gen 1 support with data rates of up to 5Gbs and the alternate modes for Display Port 1.2 (DP-Alt) and USB Power Delivery (USB-PD) supporting a power envelope of up to 100W. All signals are simultaneously present at the point-symmetric female USB-C connector with 24 signal pins. For the power modes, the solution supports all USB-PD modes as specified by the Universal Serial Bus Implementers Forum (USB-IF). Besides the USB 3.0 compliant mode with 5V and 1.5A, it can provide additional voltages of 12 and 15V with a maximum current of 3A and also 20V with 5A maximum current. Thanks to this, USB-C becomes also a unifying power supply standard for both peripheral devices and systems.

OEMs and developers can use congatec's new SMARC module and carrier board as an application ready design-in solution for off-the-shelf evaluation of this new technology. To further simplify the development of custom specific USB-C implementations, congatec also delivers all required circuit diagrams upon request and for OEM customers only. Alternatively, OEMs can leverage congatec's EDM services to have their specific solution designed for them to reduce in-house development efforts and time to market to a minimum. Furthermore, congatec is working on USB-C implementations on its Qseven and COM Express Computer-on-Modules, maximising USB connectivity to data rates of up to 40Gbs via Thunderbolt 3 for powerful COM Express Type 6 designs.
