SSE 180 is a compact embedded signal processing module designed for industrial control, telecommunications, and avionics prototyping. Combining a hexa-core RISC-V custom processor, configurable FPGA fabric, and modular I/O, the module targets applications that require deterministic throughput, low-latency networking, and ruggedized form factors. It found adoption in sectors ranging from satellite ground stations to autonomous robotics during its commercial lifespan.
Overview
The SSE 180 integrates a RISC-V based hexa-core CPU, a mid-range Xilinx compatible FPGA fabric, and an array of analog and digital I/O in a mezzanine form factor compatible with PCI Express and M.2 carriers. Its design bridged ecosystems exemplified by collaborations with ARM toolchain vendors, Intel FPGA partners, and the Linux Foundation real-time initiatives. Target markets included satellite communications players like SES S.A., aerospace contractors such as BAE Systems, and telecommunications operators including NTT and Deutsche Telekom.
Technical Specifications
The module's central processor is a custom hexa-core implementation of the RISC-V ISA running up to 1.8 GHz, paired with a FPGA fabric roughly equivalent to a Xilinx Artix series device. Primary memory options ranged from 4 GB to 16 GB LPDDR4, with storage choices including 32 GB eMMC or up to 256 GB NVMe. Connectivity supported included dual 10 Gigabit Ethernet PHYs compatible with IEEE 802.3 standards, PCIe Gen3 x4 lanes, USB 3.1, UART, SPI, I2C, and CAN FD. Secure boot used a chain-of-trust incorporating asymmetric keys and a hardware root-of-trust from partners such as Infineon and NXP. Power management leveraged PMICs from Texas Instruments and voltage supervisors common in STMicroelectronics references.
Performance and Stability
Benchmarking for deterministic latency emphasized real-time performance under Linux RT patches and Zephyr Project deployments. In network throughput tests with 10 GbE links, the SSE 180 approached line-rate forwarding with hardware offload for checksum and tunnel encapsulation, comparable to mid-tier Broadcom NIC implementations. Under thermal stress tests modeled on DO-160 environmental profiles, the module maintained frequency throttling thresholds and retained error-correcting memory resiliency akin to modules used by Lockheed Martin and Northrop Grumman. Stability in electromagnetic environments referenced compliance with standards used by NASA telemetry ground stations and ETSI EMC guidelines.
Hardware and Software Integration
Hardware interfaces were designed for rapid integration into existing carrier boards from vendors like Advantech, Kontron, and Aaeon. The FPGA fabric supported partial reconfiguration workflows used by developers familiar with Xilinx Vivado toolchains and compatible open-source flows from the SymbiFlow project. Software stacks shipped with prebuilt images for Debian, Yocto-based Linux, and real-time images for FreeRTOS and Zephyr. Toolchain support included GCC RISC-V backends, LLVM/Clang, and proprietary optimizers from vendors such as Synopsys and Cadence. Security integration mapped to FIDO-style authentication scenarios and enterprise provisioning systems used by Microsoft Azure IoT and AWS IoT Greengrass.
Applications and Use Cases
The SSE 180 was employed in a spectrum of applications: low-earth-orbit ground station modems for companies akin to SpaceX contractors, software-defined radio (SDR) platforms for research labs at institutions like MIT and Caltech, and autonomous vehicle sensor fusion demonstrators at organizations such as Waymo partners. In telecommunications, operators used the module for edge dataplane acceleration in trials by Verizon and BT Group. Industrial automation integrators used the module in rugged controllers alongside fieldbus gateways common to Siemens and Schneider Electric systems. In defense and avionics, primes used SSE 180 prototypes for mission computers adhering to DO-178C influenced toolchains and hardware-in-the-loop setups prevalent at Raytheon test facilities.
Development History and Variants
Development began in 2016 at SunElectro Systems with early reference platforms showcased at Embedded World and Mobile World Congress events. Initial silicon revisions focused on power envelope optimizations and FPGA coupling; later revisions added enhanced NVMe support and hardware crypto accelerators certified by partners like GlobalSign for secure provisioning. Notable variants included a high-temperature (-40 to +85 °C) industrial SKU used by Siemens Energy customers, a low-power variant aimed at battery-operated robotics similar to platforms used by Boston Dynamics integrators, and a secure variant with TPM-class modules endorsed by Trusted Computing Group specifications. Commercial lifecycle changes culminated in a sunset announcement in 2024 following acquisitions and roadmap consolidations involving SinoTech Industries and strategic partners.
