LPDDR4 testbed

Overview

This repository contains open hardware design files for an experimental test module in a form of SO-DIMM DDR4 module. The module includes a standard 200-ball WFBGA (10mm × 14.5mm × 0.8mm, Ø0.35 SMD) LPDDR4 RAM footprint break-routed in the SO-DOMM edge connector. The design files were prepared in KiCad. Please note that this board is not electrically compatible with off-the-shelf SO-DIMM DDR4 memory modules. It is compatible with this LPDDR4 test platform.

Questions

How big is the Lpddr4-testbed PCB?

It measures 69.6 × 30 mm and has 6 copper layers, 1.6 mm thick.

What parts does the Lpddr4-testbed use?

68 parts, built around the PCA6408APW, AT24CS01-STUM-T, MT53E1G32D2NP-046 WT:A and CC0201KRX6S5BB104. 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.

Where can I download the Lpddr4-testbed KiCad files?

From the antmicro/lpddr4-testbed repository on GitHub, at the commit this page was made from: the board is lpddr4-testbed.kicad_pcb and its schematic EEPROM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lpddr4-testbed design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
