PCI-SIG updated standards on both M.2 Gen 4 and Gen 5 in Nov. 2022
(1) M.2 Gen 4 (16 GT/s) added 3 new SSD modules- D6, D7 and D8, and defined module components’ top and bottom maximum heights. M.2 modules may have different component heights on top side and bottom side, so here is the reminder for users,
- While applying to standard or reverse mounting orientation, M.2 modules should match with different heights of connectors. For this reason, we provide multiple connectors heights: mid-mount 1.2 & 1.35mm; top-mount 2.0 ~ 10.0mm (total 15 height options)
(2) M.2 Gen 4 (16 GT/s) connector improved to support 1A current. Both housing and contact pins are modified to allow insertion of new M.2-1A cards and existing M.2 cards
(3) M.2 Gen 5 (32 GT/s) standard released 0.9 version, and the signal integrity requirements are to be determined
- We have completed M.2 Gen 5 (32 GT/s), and samples are available
