February 19 2020 - 9:00AM
Adesto Technologies Corporation (NASDAQ: IOTS), a leading provider
of innovative application-specific semiconductors and systems for
the Internet of Things (IoT), announced that its EcoXiP™ octal xSPI
flash memory device delivers high-bandwidth, power-efficient
program and data memory extension as well as eXecute-in-Place (XiP)
system operation with STMicroelectronics’ new STM32H7A3/7B3 and
STM32H7B0 microcontrollers (MCUs). With the Adesto® EcoXiP, the new
MCUs can deliver 70% higher performance while being 51% more power
efficient when running in XiP mode from EcoXiP as compared to XiP
with a standard quad flash memory device*.
The newest additions to STMicroelectronics’ STM32H7
product series – the STM32H7A3 and STM32H7B3 single core line and
the STM32H7B0 value line MCUs – are designed with power efficiency,
security, and a high level of integration to support rich graphical
interfaces, human machine interfaces (HMIs) and natural language
interfaces in next-generation smart devices. The MCUs implement a
combination of on-chip flash and two octal SPI ports, which support
NOR flash memory.
With application complexity increasing, driven by
the need for richer, more intuitive GUIs and increased processing
for capabilities such as AI, system designers need greater
flexibility in the amount of non-volatile memory (NVM) available in
their system for holding data such as images and weights. This in
turn creates a challenge for OEMs in managing many different
product SKUs. The answer lies in the ability to expand the amount
of NVM in the system using high-bandwidth, power efficient external
memory like EcoXiP while keeping the same MCU in the center of the
system design.
“Our STM32H7A3, STM32H7B3, and STM32H7B0 MCUs are
ideal for engineers who want the features of the STM32H7 series
with lower power consumption and greater integration,” said Daniel
Colonna, marketing director, Microcontroller Division,
STMicroelectronics. “For design teams providing richer graphics, we
included a dual octo-SPI interface on the new MCUs that assures
high throughput and using memory-mapped mode, treats external flash
like an internal memory during read operations. By using an octal
SPI device like Adesto’s EcoXiP with our new MCUs, designers can
create high-performance, low-power systems for more
energy-efficient, lower-cost products.”
XiP operation, where code is executed directly from
an external flash device, is also an increasing trend since it
enables designers to support growing amounts of functionality by
easily scaling their system with additional program space. EcoXiP
offers system performance comparable to executing code directly out
of internal on-chip NVM. With EcoXiP as the external flash memory,
designers can seamlessly expand their system, with easy firmware
development and don’t need to worry about which code is internal
versus external to the MCU.
“Many designers choose a quad SPI memory for their
XiP system, but depending on their application, they may have
trouble meeting performance requirements with a quad device,” said
Gideon Intrater, CTO, Adesto. “When using one of ST’s innovative
new MCUs, designers should consider XiP operation with an octal SPI
device. EcoXiP can provide significant performance advantages for
many applications, and it also improves the system power
efficiency. We’re delighted that ST implemented full support for
EcoXiP’s wrap and continue command, which contributes to its
exceptional performance.”
About EcoXiPBuilt on an innovative
memory and protocol architecture, EcoXiP was designed from the
ground-up to solve the challenges of XiP (eXecute-in-Place)
systems. EcoXiP replaces expensive, energy-inefficient memory
architectures, making power and performance trade-offs unnecessary
in a wide range of connected devices. For a broad array of MCUs and
other intelligent IoT devices, EcoXiP delivers high system
performance, optimized latency and throughput, concurrent
read-while-write capability, enhanced security, and
industry-leading standby power.
* Editor Note: In XiP performance tests, the H7A
coupled with the EcoXiP delivers 70% higher performance while being
51% more power efficient than the H7A coupled with a standard quad
flash operating at the same frequency.
