SOSA rugged Intel-based single-board computer with cyber security for embedded computing introduced by X-ES

Aug. 15, 2025
XCalibur4840 accommodates 64 gigabytes of DDR4 ECC SDRAM in four channels, as much as 256 gigabytes of onboard NAND flash, and several I/O ports.

Summary points:

  • XCalibur4840 delivers speed and security with Intel Xeon D-2800 processors and SecureCOTS technology for computationally heavy applications that need data protection.
  • It has dual 100GBASE-KR4 Ethernet ports, I/O options, and ensures high-speed data throughput and systems redundancy for mission-critical operations.
  • Its Sensor Open Systems Architecture (SOSA)-compatible pinout optimizes the XCalibur4840 for modular interoperable sensor systems in advanced defense and aerospace applications.

VERONA, Wis. – Extreme Engineering Solutions (X-ES) in Verona, Wis., is introducing the XCalibur4840 secure high-performance single-board computer for computationally heavy applications requiring maximum data protection.

The XCalibur4840 6U VPX-REDI module is based on the Intel Xeon D-2800 series (formerly Eddy Lake) of processors, and integrates SecureCOTS technology with a Microsemi PolarFire System-on-Chip (SoC) field-programmable gate array (FPGA) to protect data from being modified or observed for stringent cyber security.

The XCalibur4840 provides speed with two 100GBASE-KR4, two 1000BASE-X, and two 10/100/1000BASE-T Ethernet ports. The dual 100GBASE-KR4 Ethernet ports offer redundancy to help ensure a consistent processor throughput as fast as 100 gigabits per second always is available.


Tell me more about the Sensor Open Systems Architecture (SOSA) standard ...

  • The Sensor Open Systems Architecture (SOSA) standard is for modular, interoperable, and scalable sensor signal processing that ensures sensor integration with other systems. It enables modular design, ensures that different sensors and systems work together, and can be implemented in many sizes. SOSA helps reduce the costs of development, long-term maintenance, and upgrades, and supports the rapid adoption of emerging technologies like advanced sensors or new processing capabilities. SOSA mainly applies to radar, sonar, electronic warfare (EW), communications, satellite data collection, aircraft, uncrewed vehicles, and autonomous systems.

The XCalibur4840 accommodates as much as 64 gigabytes of DDR4 ECC SDRAM memory in four channels, as much as 256 gigabytes of onboard NAND flash, and several I/O ports like USB 2.0, PCI Express, and RS-232/422/485 serial through the backplane connectors.

The single-board computer provides additional expansion with two integrated XMC/PMC sites, which each include a x8 PCI Express connection to the Intel Xeon D processor and X12d+X8d I/O mapped to the VPX backplane connectors. Each mezzanine site offers one PMC connector, which provides a build option for P64s or X38s to the VPX backplane connectors.

The XCalibur4840 offers a Sensor Open Systems Architecture (SOSA)-aligned pinout compatible with backplane slot profile SLT6-PAY-4F1Q2U2T-10.2.1. The AMPS profile is MODA6-12.2.1-1-F2C-(2E18/E8)(4P4F)(2E2-2E3). Software support includes Wind River VxWorks and X-ES Enterprise Linux (XEL) board support packages.
