Pci Express M.2 Specification Revision 5.0 Version 1.0 Pdf [patched] Page
The PCI Express M.2 Specification Revision 5.0, Version 1.0 (May 2023) supports 32 GT/s per lane, doubling performance to approximately 15.8 GB/s for M.2 modules. It introduces specific voltage (0.75V) and amperage updates for BGA SSDs and enhanced thermal management to support higher-speed, high-performance storage. For more details, visit PCI-SIG .

The PCI Express (PCIe) M.2 Specification Revision 5.0, Version 1.0 integrates 32 GT/s signaling into the M.2 form factor, doubling the throughput of PCIe 4.0 to roughly 16 GB/s for x4 NVMe SSDs. The specification includes electrical enhancements for signal integrity, support for 0.75V core voltage in BGA SSDs, and maintained backward compatibility.

not
Crucially, this specification does introduce a new mechanical key or connector shape. Instead, it refines electrical, layout, and signal integrity requirements to make PCIe 5.0 operation possible within the existing M.2 physical footprint.
PCI Express M.2 Specification
- Trace Length Matching: Within a x4 lane group, length mismatch must be < 5 mils (0.127 mm) with intra-pair skew < 1 ps.
- Via Stubs: Back-drilling of vias is no longer optional; it’s mandatory for Gen5 to prevent stub resonance.
- AC Coupling Capacitors: Must be placed within 50 mils of the M.2 connector pins, with 0.22 µF ±10% tolerance.
