What is PCIe M.2?
PCIe M.2 is a next-generation form factor for ultra-light and thin platforms, such as smartphones, tablets, portable gaming devices, and devices requiring solid state drives (SSDs). It is a smaller and more flexible version of the PCIe Mini Card and PCIe Half Mini Card, which are commonly used in laptops and desktops.


PCIe M.2 enables the higher integration of functions onto a single form factor module solution, which can support multiple technologies and host interfaces, including Wi-Fi, Bluetooth, SSD, and wireless wide area network (WWAN). It also offers scalable performance and enhanced data rates for power-constrained platforms, allowing developers to create the optimal balance of power and performance in their platform implementations.


What are the features of PCIe M.2 Specification Revision 1.0?
The PCIe M.2 Specification Revision 1.0 was released by PCI-SIG, the organization responsible for developing and maintaining PCIe specifications, in December 2013. It defines the mechanical, electrical, thermal, and software aspects of the M.2 form factor, as well as the compliance criteria and test procedures.


Some of the key features of the PCIe M.2 Specification Revision 1.0 are:







It supports up to four lanes of PCIe 3.0, which can deliver up to 4 GB/s of bidirectional bandwidth per module.
It supports SATA 3.0 and USB 3.0 host interfaces, which can deliver up to 6 Gb/s and 5 Gb/s of data transfer rate per module, respectively.
It supports various module sizes and shapes, ranging from 16 mm x 30 mm to 22 mm x 110 mm, with single-sided or double-sided configurations.
It supports various connector types and orientations, including edge connectors and surface-mount connectors, with horizontal or vertical mating.
It supports various power states and management features, such as active state power management (ASPM), device power management (DPM), power limit indicator (PLI), and operating system-directed power management (OSPM).
