MEZU-A7G8 Module

Overview

MEZU-A7G8 is a pluggable System-on-Module (SoM) designed to streamline the implementation of custom-made Ethernet networking designs. This facilitates an easy integration of Ethernet industrial networks into equipment for the Electric, Transportation, Aerospace, and Industrial Automation sectors. The MEZU-A7G8 module is built on the AMD/Xilinx Artix-7 series FPGA.

This SoM enables the implementation of custom switches and/or end-equipment with robust networking capabilities. Network frame processing can be executed in hardware using specific SOC-E IP Cores.

What sets the MEZU-A7G8 module apart is its high level of firmware flexibility. It functions as a programmable platform, allowing customers to incorporate their own FPGA-based designs. Alternatively, it can be preprogrammed with a firmware based on SOC-E’s IP Cores, featuring technologies like HSR/PRP/RSTP for redundancy and/or PTP for time synchronization.

To facilitate its integration into customer platform, a compatible carrier board is available for purchase. A reference firmware and FPGA design is also available from SOC-E, along with carrier design files (schematics, connector information and CAD files).

With MEZU-A7G8 module, you have the power to transform your industrial network within your reach.

- USB to UART bridge
- 2x Buttons (GP I/O)
- 2x PMOD connectors
- JTAG Connector
- 2x LEDs (GP I/O)
- 2x SMA connectors (GP I/O)

MEZU-A7G8 brick consists of the following package:
- MEZU-A7G8 module (1x)
- Carrier board (1x)
- Reference firmware (predefined image) preloaded into non-volatile flash memory storage (1x)
- Power supply (1x)
- Fibre/Copper SFP modules (optional, purchased separately)
