SMARC 2.0 modules from congatec support USB-C

Further standardising the interface for SMARC 2.0, congatec offers SMARC 2.0 modules supporting powerful USB‑C connectivity. The use of the USB-C specification makes USB interconnects even more universally applicable, and further standardises the interface setup of SMARC 2.0 based embedded devices, says congatec. System designers can use USB‑C for standard peripherals from USB 3.1 to USB 1.0 and additionally for connecting displays or even the power supply to the system or peripheral devices, reducing cabling to a single cable.

The current data throughput of up to 5Gbit/s is in line with the USB 3.1 specification and 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.

According to cognatec, this universally applicable plug-and-play functionality, simplifies interconnect for embedded technology. Fully-featured USB-C jacks are rare and present a real breakthrough for standardising the fragmented world of cable-based external interconnects. Standardisation is beneficial for system engineers, system integrators, administrators and device users. System integrators can plug USB-C compliant peripherals in any USB jack available on the board for it to work.

congatec initially implements USB-C on its new conga-SA5 SMARC 2.0 Computer-on-Module and the evaluation carrier board conga-SEVAL. The USB-C functionalities include USB 2.0, USB 3.1 Gen 1 support with data rates of up to 5Gbit/s and the alternate modes for Display Port 1.2 (DP-Alt) and USB Power Delivery (USB-PD) supporting 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 format supports all USB-PD modes as specified by the Universal Serial Bus Implementers Forum (USB-IF). In addition to the USB 3.0 compliant mode with 5.0V and 1.5A, it can provide additional voltages of 12 and 15V with a maximum current of 3.0A and also 20V with 5.0A maximum current.

congatec also delivers all required circuit diagrams upon request and for OEM customers only. Alternatively, OEMs can leverage congatec’s EDM services. 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 40Gbit/s via Thunderbolt 3 for powerful COM Express Type 6 designs.
