G28I - Embedded Single Board Computer with 11th Generation Intel Core and Xeon W-11000 Processors

High Performance CPU for Embedded Applications

The duagon G28I is a 3U CompactPCI Serial CPU board featuring the 11th generation Intel Core and Intel Xeon W-11000E Series/Tiger Lake-H (TGL-H) CPUs. With up to 8 cores and up to 64 GB dual channel DDR4 RAM the G28I is well suited for high-end embedded computing in wayside railway applications or in industrial applications. As part of a rail wayside server system, the single board computer can be used for condition monitoring. The G28I offers reliable computing performance for medical applications,e.g., surgical robots as well as for factory automation, motion control and robotics in industrial automation.

Performance Scalability

CPU scalability from 25 W to 45 W TDP and 4 to 8 cores allows operation in harsh ambient temperatures of up to +60 °C system ambient temperature.

System Security and Board Management

A board management controller provides thermal supervision of the processor, a watchdog for the operating system and monitoring of onboard voltages. For system security, a Trusted Platform Module is assembled on the board.

Ruggedized Memory

The G28I includes a dual-channel 64 GB DDR4 DRAM with ECC and a transfer rate of up to 3200 MT/s which is soldered to the board to guarantee optimum shock and vibration resistance. An onboard 120 GB NVMe storage module is available on all models.

Flexible Front I/O

The G28I features three RJ45 (single-slot) Ethernet front connectors making it more cost-effective by reducing the need for extra modules. Other front I/O include one USB 3.2 Gen 2x1 connector and one USB-C connector supporting up to USB 3.2 Gen2x1 speed and DP Alternate Mode. An 8 HP board version with two 10 Gb Ethernet interfaces for high data throughput and direct connection to the network backbone is planned.

For Embedded and Harsh Environments

The G28I operates in Linux and Windows environments as well as under real-time operating systems that support Intel's multi-core architecture.

The G28I comes with a tailored heat sink. All components are soldered for protection against shock and vibration according to applicable DIN, EN or IEC industry standards. For added protection, coating and underfilling is available as an option. Long-term availability ensures an extended product life and future safety. The G28I is backwards compatible to predecessors G25A (planned G28I 8 HP product version with 10 GbE interfaces) and G23.
