Rev 2.0 PolarFire FPGA ethernet sensor bridge

31 August 2026 Computer/Embedded Technology

The shift toward compact, high performance edge AI systems is redefining sensor connectivity, pushing developers to deliver power and space efficient architectures that remain secure, scalable and future ready. To address these challenges, Microchip Technology has released Revision 2.0 of its PolarFire FPGA Ethernet Sensor Bridge, a significantly smaller, production-ready board for standardised sensor integration leveraging NVIDIA Holoscan Sensor Bridge (HSB) technology.

The Rev 2.0 HSB-enabled board delivers a 60% smaller form factor, supports twice the number of cameras, is USB C powered for streamlined rack deployment and is being offered at a lower price point than the first generation. These enhancements enable designers to replace complex, multi interface sensor connections with scalable, power-efficient 10 Gb Ethernet based architectures reducing overall system cost and bill of materials complexity. These benefits are essential for AI driven medical, industrial and humanoid robotics applications powered by NVIDIA edge computing platforms like NVIDIA Jetson and IGX.

Built on PolarFire FPGA technology, the updated design supports up to four cameras, features a camera connector that is compatible with NVIDIA Jetson and includes onboard optical latency measurement circuitry. This helps enable end-to-end latency validation – from sensor capture to AI inference – using NVIDIA Latency Display Analysis Tool.

The board features an FPGA Mezzanine Card (FMC) expansion connector that supports future feature growth and supports interfaces including MIPI CSI 2, I2C, UART and GPIO. The flexible design allows support for multiple sensor and video interfaces such as SLVS EC 2.0, 12G SDI, HDMI and DisplayPort, without requiring a redesign of the core platform. A standard PMOD connector further enhances system extensibility.

Leveraging the power-efficiency, security and reliability of PolarFire FPGAs, the HSB-enabled board delivers real-time, multi-sensor data processing over Ethernet in compact, power constrained edge environments. Built in security and safety features help protect edge AI devices and support reliable long term deployment. Integration with the NVIDIA Holoscan SDK helps accelerate development with optimised libraries, AI models and reference applications.
