Onsemi has released a new RSL15 wireless microcontroller (MCU) to meet the security requirements of Internet industrial applications.
As a leading manufacturer of smart power and smart perception technology, Onsemi's RSL15 features an Arm security Cortex-M33 processor running at 48MHz, and Bluetooth low energy 5.2 wireless technology.
“RSL15 was certified by the Embedded Microprocessor Benchmark Consortium,” said Onsemi. “The ULPMark CoreMark measures the energy efficiency of microcontrollers used in embedded systems while active. RSL15 now leads its class by attaining a ‘performance’ score of 60.5. Within the ULPMark CoreProfile, which calculates the deep sleep efficiency, On Semi has the top two placements with the RSL10 and RSL15 respectively.”
RSL15 scores 5.2 energy efficiency in the EEMBC ULPP CoreMark project, which will help many applications achieve longer battery life. In addition, RSL15 supports a series of new functions provided by the Bluetooth 5.2 specification, including longer distances, higher data transmission, and positioning via AoA and AoD. Bluetooth hardware supports up to 10 simultaneous connections, remote (encoding PHY), 2Mbit PHY, angle of arrival, angle of departure, and advertising expansion, and is backward compatible with Bluetooth Low Energy 5.1, 5.0, 4.2, 4.1 and 4.0.
The Arm TrustZone virtualization and CryptoCell-312 adopted have secure boot, device root of trust, life cycle management and security key management, providing security guarantees for applications and software. Onsemi has also developed an innovative intelligent perception function that enables the Arm Cortex-M33 processor to monitor the sensor interface while maintaining deep sleep mode.
