Geneva, June
16,
2022 –
STMicroelectronics (NYSE: STM), a global
semiconductor leader serving customers across the spectrum of
electronics applications, has introduced new inertial sensors that
contain the intelligent sensor processing unit (ISPU) to power the
onlife era: interacting with trained devices with intelligence
moving from “on” the edge to “in” the edge.
The ISM330ISN always-on 6-axis inertial measurement unit (IMU)
for movement and position sensing uses its embedded intelligence to
deliver unrivaled performance and accuracy for its size and power.
Ideal for IoT and industrial applications, ST’s new IMU sets to
accelerate response time and extend battery life in equipment such
as condition monitors for predictive maintenance, as well as
battery-operated asset trackers and industrial applications such as
robots.
The intelligence built into the ISM330ISN enables smart devices
to perform advanced motion-detection functions in the sensor
without interaction with the external microcontroller (MCU), thus
saving power at system level. ST’s approach integrates a
specialized processor, the ISPU, in a small area directly on the
sensor chip, optimized for machine-learning applications. This
enables the ISM330ISN module to have a 50% smaller footprint and
consume 50% less power than a typical co-packaged MCU.
Developers can program the ISPU using ST’s NanoEdge AI Studio, a
market-proven ST tool that many customers have used to deploy AI
applications on STM32 microcontrollers. This technology is now
available for programming the ISPU, enabling users to easily
generate automatically optimized machine-learning libraries.
Designing an anomaly detection library with AI learning capability
directly inside the ISPU is possible with minimal data and just a
few clicks. No specific data-science skills are needed.
“Intelligence formerly implemented at the network edge, in an
application processor, is now moving to the deep edge, inside the
sensor,” said Simone Ferri, General Manager of Marketing, Analog
MEMS and Sensors Group, STMicroelectronics. “Our ISM330ISN IMU
heralds a new category of smart sensors, leveraging embedded AI to
handle complex operations such as pattern recognition and anomaly
detection with greatly increased efficiency and performance.”
While presenting new AI-powered creative opportunities, the
ISM330ISN has the same 3mm x 2.5mm x 0.83mm package outline as
conventional inertial modules. Hence designers can upgrade their
products quickly and cost-effectively with no obligation to change
an established circuit board layout.
The ISM330ISN is covered by ST’s 10-year longevity program,
which provides long-term availability assurance for product
designers and manufacturers.
Further technical information
The ISM330ISN is part of ST’s iNEMO family of IMUs. It contains
a 3-axis accelerometer and 3-axis gyroscope with low-noise sensing
performance, and an output data rate (ODR) of 6.6kHz. With the
ISPU, the sensor ensures consistently high accuracy while consuming
only 0.59mA in combination mode with the accelerometer and
gyroscope active.
ST’s ISPU architecture, based on digital signal processing
(DSP), is extremely compact and power-efficient, with 40Kbytes of
RAM and occupying just 8000 gates on the sensor die. Performing
floating-point operations with single-bit precision, ISPU is ideal
for machine-learning applications and binary neural networks.
ST’s ISPU and the NanoEdge.AI tools have been shortlisted for
the Embedded Award at Embedded World 2022, in the Hardware and
Software categories respectively. The event takes place in
Nuremberg, Germany, June 21-23. ST will be exhibiting during the
show, at booth no. 148 hall 4A.
The ISM330ISN is scheduled to enter production in H2 2022 and
will be available from st.com or distributors for $3.48 for orders
of 1000 pieces. NanoEdge AI Studio enabling the creation of
libraries designed for specific ISPU part numbers is available
at no charge on ST.com. Please contact your local ST sales
