Simplifies Designing with High-Bandwidth,
HyperBus-based HyperFlash™ and HyperRAM™ Memories for Faster
Response Times in Autonomous Driving and Industry 4.0
Applications
Cypress Semiconductor Corp. (Nasdaq: CY), a global leader in
embedded systems solutions, today announced the inclusion of
Cypress' high-bandwidth HyperBus™ 8-bit serial memory interface
into the new eXpanded SPI (xSPI) electrical interface standard from
the JEDEC Solid State Technology Association. The xSPI standard
defines requirements for the compatibility of high-performance x8
serial interfaces, enabling controller and chipset manufacturers to
design a universal memory controller. The inclusion of the HyperBus
interface in the JEDEC xSPI standard simplifies designing in
HyperBus-based memories and provides more flexibility to system
designers to implement instant-on functionality in automotive,
industrial and IoT applications.

Cypress was the first NOR flash memory supplier to identify the
market requirement for a high-speed, 8-bit bus and introduced the
HyperBus interface in 2014, ushering in a new class of
high-performance NOR flash and RAM solutions that enable instant-on
functionality for autonomous driving and industry 4.0 applications.
Cypress' HyperBus-based memories include high-density HyperFlash™
NOR Flash devices with the bandwidth required for the
highest-performance embedded systems and high-speed HyperRAM™
self-refresh Dynamic RAM (DRAM) devices for systems requiring
expanded scratchpad memory. More information on Cypress' HyperBus
interface and industry-leading high-performance memory portfolio is
available at http://www.cypress.com/products/hyperbus-memory.
"Cypress continues to be a driving member of the JEDEC working
committee that developed and proposed the xSPI standard," said
Howard Sussman, a JEDEC Board of Directors Vice-Chairman. "For
system integrators, the JEDEC standard provides the means to easily
second-source xSPI-compliant Flash devices. Use of the standard
provides a single PCB package footprint and enables a unified
device driver for all xSPI memories that configures the memory
system based on a standardized xSPI method."
The xSPI standard defines requirements for the compatibility of
high-performance x8 serial interfaces, including read and write
commands, electrical characteristics, signaling protocols for
command and data transfers, and a standard pin-out in a Ball Grid
Array (BGA) footprint.
"We firmly believe an open industry standard from a recognized
standardization body such as JEDEC is the best way to generate
broad market support that benefits both customers and suppliers,"
said Rainer Hoehler, Vice President of the Flash Business Unit at
Cypress. "Having our HyperBus interface incorporated into the xSPI
standard will make it easier for our customers to bring the
convenience of instant-on to their systems."
About Cypress HyperBus Interface
The efficient 12-pin Cypress HyperBus interface consists of an
8-pin address/data bus, a differential clock (2 signals), one chip
select and a read data strobe for the controller, reducing the
overall cost of a system. Memories based on the interface enable
faster systems with quicker response times and rich user
experiences. The HyperBus interface enables a wide range of
high-performance applications, such as automotive instrument
clusters, infotainment and navigation systems and factory
automation systems.
