STMicroelectronics releases long-range
wireless microcontrollers for energy-efficient connectivity in
smart metering, smart building, and industrial
monitoring
New STM32 system-on-chip with low power and
multi-protocol support simplifies wireless system design for
diverse use cases
Geneva, Switzerland, November 20, 2023 –
STMicroelectronics (NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics
applications, has released a new microcontroller (MCU) that fuses
the Company’s expertise in wireless-device design with its
high-performing and efficient STM32 architecture. Novel
power-saving features enable the extension of battery life in the
new wireless MCUs beyond 15 years.
Especially valuable in remotely deployed applications including
metering and monitoring devices and data from alarm systems,
actuators, and sensors in today’s smart buildings, smart factories,
and smart cities, the STM32WL3 wireless MCUs can help limit power
consumption and prioritize activities. Adoption and use of these
efficient MCUs can lead to improved user experience, service
delivery, and reduced environmental footprint. Device and
application designers can leverage ST’s wireless MCUs to develop
and deliver new products to the world quickly for maximum
benefit.
The latest innovation in ST’s lineup of integrated wireless
chips, the STM32WL3 contains an advanced, power-efficient
multi-protocol radio suitable for long-range communication using
license-free frequency bands reserved globally for industrial,
scientific, and medical (ISM) applications. In addition to the main
radio, ST has integrated an industry-unique ultra-low-power radio
the system can power-down to save energy while listening
continuously for a wake-up signal.
Lead customers are using STM32WL3 MCUs to add value to smart
connected devices. For example, Lierda Internet of Things
Technology, is using the STM32WL33 to reduce power and add long
range wireless connectivity to existing networking products.
Leveraging the MCU’s wake-up radio to minimize power consumption,
the Lierda module monitors and maintains network equipment across a
point-to-point or point-to-multipoint wireless connection.
Another customer, Silent Smart Technology, has created a family
of modules based on STM32WL3 wireless MCUs that operate in various
sub-1GHz frequency bands. The modules support multiple transmission
modes, channel monitoring, wireless relay, and other functions. The
MCU’s wakeup feature allows the modules to operate in deep-sleep
mode, consuming only about 1µA overall current while remaining
ready to return to full operation.
“ST’s new highly featured, long-range STM32WL3 wireless
microcontrollers help customers like Lierda and Silent Smart create
innovative and flexible products, achieving very low power and fast
time to market,” said Benoit Rodriguez, Wireless Business Line
General Manager, STMicroelectronics. “Special features such as the
wake-up radio and our flow-metering LC sensor controller enable
energy-saving designs in smart metering, smart agriculture, and
asset tracking that run for up to 15 years from a small
battery.”
The STM32WL3 joins ST’s growing family of devices that combine
the radio with the main application controller to ease engineering
challenges, reduce power and size, and enhance reliability.
Further technical information:
- The long-range radio on the STM32WL3 MCUs operates in the
internationally designated license-free frequency bands, 413MHz -
479MHz and 826MHz - 958MHz, with the support for 169MHz coming in
2024.
- The radio is multi-protocol and multi-modulation capable,
supporting 4-(G)FSK up to 600kbit/s, 2-(G)FSK, (G)MSK, DBPSK, DSSS,
OOK, ASK modulation schemes to maximize versatility and ease
deployment.
- On-board peripherals include an LCD driver, a 12-bit 1Msample/s
ADC, analog comparator, DAC, and multiple timers. Together with an
integrated balun, RF power amplifier, and SMPS, they minimize
external BoM for a cost-optimized solution with short
time-to-market.
The complete lineup contains devices with Flash density from
64KB to 256KB and 16KB or 32KB RAM, in a 32-pin or 48-pin VFQFPN
package. There is also an extended temperature range option, from
-40°C to 105°C. All variants are covered with ST’s 10-year
longevity guarantee for industrial products. Sample quantities are
available now.
Tailored to the specific needs of smart-metering applications,
the STM32WL3 embeds an LCD controller and a specific peripheral --
LC sensor controller – for fluid flow measurement that eases the
design of water meters and heat-cost allocators. Multi-protocol
support enables cost-efficient deployment of one single platform
over different long-range wireless technologies, including Sigfox,
KNX, mioty, M-Bus, and others.
Prices start from $2.04 for orders of 10,000 pieces. For larger
quantity pricing, please contact your ST sales office. Evaluation
kits will be available shortly.
