Adesto Takes Ultra-low Power Memory to the Next Level: New FusionHD™ is up to 70% Lower Power than Standard Flash
February 25 2019 - 9:00AM
Adesto® Technologies Corporation (NASDAQ: IOTS), a leading
provider of innovative application-specific semiconductors and
embedded systems for the IoT era, introduces new FusionHD™
non-volatile memories (NVMs) designed for next-generation consumer
and industrial IoT edge devices. FusionHD builds on the Smart IoT
feature set of Adesto’s highly successful Fusion family with even
more capabilities, patented low-power technology, security
features, and increased memory density options.
The FusionHD product line supports the code storage and data
logging demands of a wide range of feature-rich wearables,
hearables, sensor edge devices and industrial systems. It delivers
low power consumption, fast data transfer and robust,
high-reliability operation. Unlike standard flash devices, FusionHD
incorporates a Small Page Erase and Write Architecture that makes
saving small packets of data quick and efficient. It also allows
large data packets to be saved and accessed using minimal CPU clock
cycles, reducing processing time and battery consumption.
“When we first introduced the Fusion family of NVMs, their novel
design and ultra-low power operation helped extend battery life in
a new generation of products such as Bluetooth® LE enabled consumer
IoT devices,” said Paul Hill, senior marketing director, Adesto.
“Fusion quickly became our fastest-growing NVM family, and we
expect FusionHD to achieve even greater success. The product adds
powerful new features to address evolving market needs, and
provides significant advantages across a wide range of demanding
applications.”
FusionHD can bring system-level advantages to long-life
industrial IoT devices such as sensors, meters and monitors. The
extended battery life and wide operating voltage range offered by
FusionHD help to prolong the active lifetime of these devices,
which are often in remote or inaccessible locations. Designed and
tested to Adesto’s high reliability standards, FusionHD offers
increased robustness over other devices – a benefit when repair and
maintenance aren’t possible for extended periods.
“Whether the key design priority is low-power consumption,
reliable remote operation, or small form factor, FusionHD can
provide significant advantages for your design,” commented
Hill.
“As the processing requirements at the IoT edge continue to
increase, designers must look for every possible opportunity to
optimize their system design for their specific application,” said
Rich Wawrzyniak, principal analyst for ASIC & SoC at Semico
Research Corp. “There are opportunities to make a difference at the
edge by using the right non-volatile memories, such as those with
higher densities, lower-power operation, security features, and the
ability to perform fast, efficient offline data logging. With its
new FusionHD memories, Adesto is delivering these features and
more.”
FusionHD includes a new suite of intelligent supervisory
functions including a Battery Health Monitor and System Reset
Generator, which reduce the system bill-of-materials (BOM), overall
system cost and physical footprint.
In addition, FusionHD provides a range of innovative features
specifically designed for power-conscious IoT edge devices:
- Flexible Memory Architecture
- A flexible new Read/Write SRAM buffer reduces the number of
times needed to write to the flash array, dramatically improving
endurance while also decreasing CPU clock cycles and reducing power
consumption.
- The Small Page Erase and Write Architecture is ideal for
writing small amounts of data without having to reprogram an entire
page, thereby lending speed, power and endurance to the
device.
- Intelligent host interface features that elevate the memory
device into the ‘smart peripheral’ domain
- The unique Active IRQ feature enables the device to issue an
interrupt to the MCU after completing an internal program or erase
operation, optimizing overall power use and reducing CPU
overhead.
- Read/Modify/Write operation enables easier software driver
development and allows the CPU to focus on other tasks.
- Security features include unique device identification and a
User One-Time Programmable (OTP) security register that is usable
for system-level key storage.
FusionHD by the Numbers
- The power consumption of FusionHD devices is up to 70% lower
than the competition, aided by the Small Page Erase feature,
autonomous smart features as well as an optimized low-power design
with ultra-deep power-down mode.
- FusionHD enables up to 5x faster system performance versus the
competition, with features like small page erase,
Read/Modify/Write, and flexible SRAM buffer; it also achieves
104MHz SPI operation; QSPI with XiP capability allows direct code
execution from the host MCU.
- FusionHD products extend the Fusion product line up to 32Mbit
to support the growing memory demands of power-sensitive
products.
- A wide operating voltage range of VCC 1.7V to 3.6V allows
FusionHD to function with a broad variety of battery technologies
and to operate from an unregulated supply voltage, potentially
reducing overall BOM cost.
FusionHD supports the new Serial Flash Reset Signaling Protocol
(JESD252) and the latest version of the SFDP standard (JESD216D).
These standards make it easier for system designers to deliver
smarter, more efficient and user-friendly devices.
Adesto will demonstrate FusionHD in its booth 4A:124 at the
Embedded World Exhibition, being held February 26-28, 2019 in
Nuremberg, Germany.
