The new STM32 system chip has low power consumption and supports multiple wireless communication protocols, simplifying wireless system design for various purposes
STMicroelectronics, a globally leading semiconductor company serving multiple electronic application fields, has released a new microcontroller (MCU) that integrates wireless chip design expertise with high-performance and energy-efficient STM32 system architecture. The new energy-saving feature extends the battery life of this wireless MCU to over 15 years.
In the application field of long-distance deployment, including energy metering, monitoring equipment, alarm systems, actuators, as well as sensors for smart buildings, smart factories, and smart cities, the STM32WL3 wireless MCU is particularly useful in controlling power consumption and prioritizing work. These high-efficiency MCUs can improve user experience, provide services, and reduce environmental footprint. By using wireless MCUs from STMicroelectronics, device and application designers can quickly develop new products and achieve maximum economic benefits.
STM32WL3 is the latest innovative product of STF Semiconductor‘s highly integrated wireless chip series, equipped with advanced energy efficiency, multi protocol RF transceivers, and using globally licensed industrial, scientific, and medical (ISM) dedicated radio bands for long-distance communication. In addition to the main RF transceiver, the new microcontroller also integrates the industry‘s unique ultra-low power RF transceiver. During continuous monitoring of wake-up signals, the system can turn off this sub RF transceiver to save energy.
Prospective customers are using STM32WL3 MCU to enhance the product value of smart connectivity devices. For example, Lierda IoT Technology is using STM32WL33 to reduce power consumption and add remote wireless connectivity to existing network products. The Lierda module utilizes the wake-up RF function of the MCU to minimize system power consumption, monitor and maintain wireless network devices with point-to-point or point-to-point connections.
Another customer, Silent Smart Technology, has developed a series of sub 1GHz wireless communication modules based on STM32WL3 wireless MCU. These modules support multiple transmission modes, channel monitoring, wireless relay, and other functions. The wake-up function of the MCU allows the module to enter deep sleep mode, with a working current of only about 1 µ A, while maintaining a ready state to resume normal operation at any time.
Benoit Rodriguez, General Manager of the Wireless Business Line at STMicroelectronics, stated: ST‘s newly launched STM32WL3 multifunctional long-distance wireless microcontroller can help customers such as Lierda and Silent Smart develop innovative and flexible products, significantly reducing product power consumption and shortening product launch time. With special features such as wake-up RF transceivers and flow metering LC induction controllers, developers can design high-energy connection functions for intelligent metering, intelligent agriculture, and asset tracking products, which can last for 15 years with a small capacity battery Long.
