Onsemi has announced its secure RSL15 wireless microcontroller (MCU) featuring low power consumption. Enabled with Bluetooth Low Energy wireless connectivity, the RSL15 addresses the growing demand of connected industrial applications for security without sacrificing power consumption, says the company.
To validate 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 the RSL10 and RSL15 respectively.
While preserving its power consumption, the RSL15 is designed with ArmTrustZone 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 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 will continue 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.
The RSL15 is available now in a miniature 40-pin QFN package.
