New version doubles the peak data transmission rate compared to the
previous release

The updated specification has been incorporated into JEDEC’s new UFS
Version 3.0 to support storage products deployed in smartphones, tablets
and automobiles

PISCATAWAY, N.J.–(BUSINESS WIRE)–#MIPI–The MIPI
Alliance
, an international organization that develops interface
specifications for mobile and mobile-influenced industries, today
released MIPI
UniPro v1.8
, an update to the versatile transport layer that is used
to interconnect chipsets and peripheral components in mobile-connected
devices.

MIPI UniPro v1.8 delivers dramatically higher data speeds compared to
the previous release and incorporates techniques that ensure the quality
of high-throughput transmissions. The first adopter of this latest
specification is the JEDEC Solid State Technology Association. JEDEC is
using MIPI UniPro v1.8 to provide the interconnection layer for
Universal Flash Storage (UFS) version 3.0 memory components deployed in
smartphones, tablets and mobile computing products, as well as
infotainment platforms and telematics hubs used in automotive systems.

“MIPI UniPro is a mature, general-purpose interface that is easy to
implement, flexible for use in traditional and modular device
architectures and tailored to meet and respond to ongoing needs in
mobile and other industries,” said Joel Huloux, chairman of MIPI
Alliance.

“JEDEC’s early adoption of MIPI UniPro v1.8 demonstrates the
applicability of the new specification in the evolving memory storage
industry. We expect to see many more compelling smartphone and laptop
applications as the mobile industry transitions to 5G, and we look
forward to working with our members and additional industry
organizations to broaden the specification’s reach into connected car
systems and other emerging platforms.”

The MIPI UniPro protocol is deployed on MIPI
M-PHY
at the physical layer. The new v1.8 release operates on the
most recent version of MIPI M-PHY, v4.1, to achieve significant
improvements in throughput, system performance and service quality.

Key characteristics of MIPI UniPro v1.8 include:

  • Capability to use the MIPI M-PHY v4.1 transmission mode known as “High
    Speed GEAR 4” to achieve 11.6 gigabits per second (Gbps) data rates
    per lane—a 2x performance increase over the previous (v1.61)
    specification.
  • Ability to continuously monitor the bit error rate of forward and
    reverse links, as well as receiver performance. MIPI UniPro v1.8 is
    able to “retrain” the communication channel dynamically. The
    retraining feature updates link settings if needed to ensure a link
    delivers the same reliability and quality of service (QoS) at higher
    data speeds as it provided for lower speeds via the v1.61
    specification.
  • The QoS features can be used to ensure reliability of data
    transmissions in systems that are subject to highly variable and
    potentially extreme temperature conditions as can be found, for
    instance, in automotive applications.
  • The QoS features can also monitor and address performance issues
    associated with aging interconnects to help extend the lifespan of
    deployed systems.
  • MIPI UniPro v1.8 links can be implemented on as few as four wires,
    which streamlines integration and helps reduce costs. Upgrading to the
    new release from v1.61 is convenient and provides backward
    compatibility to the previous specification.

“MIPI UniPro v1.8 is all about improving performance. Its dynamic link
updates and link-training features will ensure that components
interconnected with the technology will operate as intended at the
higher speeds,” said Juergen Urban, chair of the MIPI Alliance UniPro
Working Group. “MIPI Alliance will continue to evolve MIPI UniPro and
MIPI M-PHY to meet future requirements for mobile and automotive
applications.”

Interoperability Test Workshops

MIPI Alliance frequently hosts interoperability test workshops to help
developers build successful implementations with MIPI UniPro. The most
recent workshop, held in Taiwan in October 2017, gave
developers an early opportunity to test
forthcoming designs based on
MIPI UniPro v1.8 with MIPI M-PHY v4.1. More information about future
interoperability workshops, please visit https://mipi.org/events.
