Duagon’s SBC has up to eight cores to operate in rail systems

A 3U CompactPCI serial CPU board by Duagon features the 11th generation Intel Core and Intel Xeon W-11000E series processors / Tiger Lake-H CPUs. The G28 has up to eight cores and up to 64Gbyte RAM and is suitable for embedded computing for rail systems (onboard and trackside) as well as for the medical and critical automation industries. 

Optional 10Gbit Ethernet interfaces allow for high data throughput and direct connection to the network backbone.

For a robust performance in harsh environments, DRAM (up to 64Gbyte DDR DRAM with error code correction or ECC) is soldered to the board, the components are underfilled and additionally coated to guarantee optimum shock and vibration resistance and durability against harsh environmental conditions. The CPU is scalable from 25 to 45W TDP (thermal dynamic performance) and four to eight cores allows operation in ambient temperatures of up to +85 degrees C with active cooling. According to Duagon, a single board can cover different environmental conditions and market applications.

In onboard rail applications, the G28 can be used as central maintenance and virtualisation platform and main computing unit for passenger Wi-Fi and internet access. As part of a rail wayside server system, the SBC can be used for condition monitoring and in medical applications, the G28 can be used in surgical robots. It can also be used in factory automation for motion control and robotics in industrial automation.

For system security, a Trusted Platform Module (TPM 2.0) is assembled. This provides the G28 support for remote device authentication, measured boot, and secure updates. There is also an independent board management controller (BMC) which monitors onboard voltages, current and temperature. It also performs dedicated tasks like external watchdog management, power supply control and reset handling.

The G28 features three RJ45 or two M12 Ethernet front connectors, one USB 3.2 Gen 2×1 connector and one USB-C connector for one USB 3.2 Gen 2×1 and one DisplayPort. Main backplane interfaces include four SATA (6Gbit), eight PCIe 3.0 root ports with lane configurations of one, four or eight, and two 1Gbit Ethernet ports.

The SBC is supported by Linux Yocto Project, Windows 10 IoT Enterprise 64-bit as well as real time operating systems (RTOS) that supports Intel’s multi-core architecture. 

Duagon also offers long-term availability of the components for a minimum of 10 years. The G28 is backwards compatible to the predecessor products G25, G25A and G23.

The fully qualified G28 will be available from September 2022.
