FlorianFrank/MemTestX1A comprehensive test platform for advanced memory device characterization combining FPGA acceleration, real-time firmware, and automated experiment scheduling
Fmc memory adapter is an open-source printed circuit board by FlorianFrank, from the FlorianFrank/MemTestX repository on GitHub, published under the Apache-2.0 licence. It is a 4-layer board of 200.1 × 170.2 mm with 36 parts on 541 nets, routed with 16,518 tracks and 151 vias.
It is built around the SN74AVC8T245PWG4 and ASP-134488-02. Its parts include 12 capacitors, 9 connectors and 6 ICs. It belongs with the interfaces and adapters boards of this library.
This directory contains a reference adapter board design that can be adapted to different memory types. The current implementation targets the Lapis Semiconductor MR48V256C FRAM memory module.
A 3D rendering of the board is shown below:
To adapt the design to a different memory device (including alternative packages):
Adapter_Template_Rohm_FRAM.pro)The design was created using KiCad 8.0.7.
The schematic is shown below for reference:
To adapt the footprint:
Assign the footprint to Symbol U2
Export the Netlist `File -> Export -> Netlist``
Open the PCB design (Adapter_Template_Rohm_FRAM.kicad_pcb)
Import the netlist and route the design.
Rooting may be automized for example by using freerouting

It measures 200.1 × 170.2 mm and has 4 copper layers, 1.6 mm thick.
36 parts, built around the SN74AVC8T245PWG4 and ASP-134488-02. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the FlorianFrank/MemTestX repository on GitHub, at the commit this page was made from: the board is hardware/pcbs/fmc_memory_adapter/fmc_memory_adapter.kicad_pcb and its schematic hardware/pcbs/fmc_memory_adapter/fmc_memory_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
