Internet of Things Product of the Year
Product Name: RSL15
RSL15 ultra low power secure Bluetooth microcontroller
Providing a record setting, ‘industry lowest’ power consumption figure, the RSL15 wireless microcontroller (MCU) from onsemi offers enhanced security and processing capabilities with innovative smart sensing features. Enabled with Bluetooth® Low Energy wireless connectivity, the RSL15 addresses the growing demand of connected industrial applications for security without sacrificing power consumption.
Not just bold claims, officially validating its energy efficiency, the RSL15 was certified by the Embedded Microprocessor Benchmark Consortium (EEMBC). The organization’s ULPMark™-CoreMark benchmark program measures the energy efficiency of microcontrollers used in embedded systems while active. The RSL15 now leads its class by attaining a ‘performance’ score of 60.5. Within the ULPMark- CoreProfile benchmark, which calculates the deep sleep efficiency of MCUs, onsemi has also maintained the top two placements with its RSL10 and RSL15 respectively.
RSL15 is an ultralow power secure Arm® Cortex®M33 processor based Bluetooth Low Energy 5.2 wireless MCU designed for connected smart devices in industrial and medical applications. With built-in power management, a wide supply voltage range, flexible GPIO and clocking scheme and an extensive set of peripherals, the RSL15 offers maximum design flexibility for high performance and ultra-low-power applications. The RSL15 includes 80 kB RAM and is available in 284 kB or 512 kB Flash options.
“From beacons for contact tracing to trackable asset tags, there are millions of connected devices globally operating off small batteries,” said Patrick Moorhead, CEO, founder and chief analyst at Moor Insights & Strategy, “By setting a new record in Bluetooth 5.2 energy efficiency in the EEMBC ULPMark™ CoreMark program, the RSL15 will help these applications, amongst many others, achieve a battery life greater than they ever thought to be possible.”
While preserving its state-of-the-art power consumption, the RSL15 is designed with Arm®TrustZone® technology to establish device root of trust as well as Arm CryptoCell™-312 technology to protect the authenticity, integrity and confidentiality of code and data. This PSA Level 1 certified design enhances the security measures already offered as part of the Bluetooth protocol, providing assurance at both the application and software levels.
“The ability to protect against cyber threats is an essential differentiator for manufacturers choosing a wireless microcontroller for industrial IoT applications,” said Michel De Mey, vice president of the industrial solutions division at onsemi. “With its advanced system-level security features and class-leading energy efficiency, the RSL15 provides a comprehensive wireless solution that OEMs and consumers can rely on.”
RSL15 supports a number of new capabilities provided by the Bluetooth 5.2 specification, including longer range, higher data transmissions and localization through angle of arrival (AoA) and angle of departure (AoD). onsemi has also developed an innovative smart sensing feature that allows the Arm Cortex®-M33 processor to remain in a deep sleep mode while still monitoring sensor interfaces. With these advanced new features, the RSL15 continues the success of the RSL10 radio family, which has been integrated into a variety of industrial automation applications including connected asset tracking, smart retail and IoT edge nodes.
Saving time for designers, the comprehensive yet easy to use Software Development Kit provides sample applications that demonstrate the hardware capabilities to enable security with the Cybersecurity Platform, acquire sensor data in Smart Sense mode, configure the built in power management and utilize Bluetooth Low Energy features. The RSL15 is available in a miniature 40-pin QFN package.
