microSD Express joins SD Express in integrating PCIe® and NVMe™ for up to 985 MB/sec transfer rate with backwards compatibility
(BUSINESS WIRE) -- Mobile World Congress Booth #CS120 — The SD Association announced today microSD Express, offering the popular PCI Express® and
NVMe™ interfaces alongside the legacy microSD interface for backwards
compatibility. Like SD Express, microSD Express uses the PCIe interface
delivering a 985 megabytes per second (MB/s) maximum data transfer rate
and the NVMe upper layer protocol enables advanced memory access
mechanism, enabling a new world of opportunities for mobile devices.
microSD
Express cards defined in the SD 7.1 specification will be offered in a
variety of capacities such as microSDHC Express, microSDXC Express and
microSDUC Express. An updated video provides an overview of microSD Express and SD Express.
“microSD
Express gives the mobile industry a compelling new choice to equip
mobile devices with removable SSDs,” said Hiroyuki Sakamoto, SDA
president. “SD 7.1 prepares consumers and mobile device manufacturers to
meet ever increasing storage demands for years to come.”
“PCI-SIG is
pleased to continue our collaboration with the SDA on this newest
innovation for the world’s leading removable memory card – microSD,”
said Al Yanes, PCI-SIG president and chairman. “PCIe specification
conformance tests are available today by major test vendors, offering a
significant advantage for any new PCIe adopter.”
microSD
Express delivers speeds necessary to transfer large amounts of
information generated by data-intense wireless communication, speed
hungry applications running on cards and mobile computing devices, ever
evolving gaming systems, multi-channel IoT devices, numerous automotive
uses, higher resolution mobile videos, action cameras, 360o videos, VR and more.
“NVMe is the
industry-recognized performance SSD interface from the client to the
data center to mobile, shipping in millions of units,” said Amber
Huffman, NVM Express® Inc. president. “By SDA adopting NVMe technology
into the new microSD Express cards, users can experience lower latency
and increasingly fast transfer speeds across various applications.”
microSD
Express uses the well-known PCIe 3.1 and NVMe v1.3 specifications
defined by PCI-SIG® and NVM Express, respectively, on the second row of
pins. PCIe 3.1 includes the low power sub-states (L1.1, L1.2) enabling
low power implementations of SD Express for the mobile market. In
addition, SD Express cards with significantly higher speed data transfer
rates are expected to consume less energy than traditional microSD
memory cards while keeping the same maximum consumed power. The cards
provide system developers new options offered by PCIe and NVMe
capabilities, such as Bus Mastering, Multi Queue (without locking
mechanism) and Host Memory Buffer. By relying on successful protocols
already in the marketplace, the SDA gives the industry an advantage
allowing utilization of existing test equipment and saving in
development process by usage of existing building blocks used in
existing designs.
The SDA
released visual marks to denote microSD Express memory cards to make
matching the card and device easier for optimal device performance.
The SDA revised its white paper, “SD Express Memory Cards with PCIe and NVMe Interfaces,”
that provides more details on the new capabilities and features found
in the SD 7.1 specification. It also introduced a new white paper “SD Express and microSD Express Memory Cards: The Best Choice for Your Future Product Designs” providing product engineers with an in-depth look at the opportunities now available. More information is available on our website.
Find the SDA at Mobile World Congress Barcelona in Booth CS 120 February 25-28, 2019, in the Fira Gran Via, Barcelona, Spain. The SDA is also at embedded world in Booth 3A-524 February 26-28, in the Exhibition Centre Nuremberg, Nuremberg, Germany.
