VERONA, Wis. – Extreme Engineering Solutions (X-ES) in Verona, Wis., is introducing the XCalibur5340 high-performance 6U VPX single-board computer for mission-critical military, aerospace, and defense applications that must work in rugged environments.

Built around the Intel Core Ultra Series 3 processor (formerly code named Panther Lake), the XCalibur5340 offers advanced compute capabilities tailored for high-bandwidth information processing.

The computer board integrates SecureCOTS trusted computing technology with a Microchip PolarFire systems-on-chip field-programmable gate array (FPGA) to enable on-board custom logic and data protection to support secure applications without the need for external security hardware.

Onboard memory

XCalibur5340 supports as much as 64 gigabytes of LPDDR5 SDRAM with in-band ECC and as much as 512 gigabytes NVMe onboard data storage to provide high memory bandwidth and capacity for demanding workloads.

The single-board computer offers high-speed interfaces like 100 GBASE-KR4, 25 GBASE-KR Ethernet, USB 2.0, PCI Express Gen4, and several serial communications options through VPX backplane connectors.

The embedded computing board aligns with the Sensor Open System Architecture (SOSA) Payload profile. Software support includes Wind River VxWorks, X-ES Enterprise Linux (XEL), and Linux Yocto BSPs.
