RSL15 Bluetooth® 5.2 Secure Wireless MCU
onsemi's RSL15 Bluetooth 5.2 secure wireless MCU is designed for connected smart devices in industrial and medical applications
onsemi’s RSL15 is an ultra-low-power secure Arm® Cortex®-M33 processor-based Bluetooth Low Energy (BLE) 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.
- Industry leading general-purpose microcontroller (MCU)
- Industry’s lowest power Flash-based secure Bluetooth low energy MCU
- Latest in embedded security with root of trust
- Bluetooth low energy 5.2 with long range and localization
The comprehensive yet easy-to-use software development kit (SDK) contains drivers, libraries, sample code, development tools, and mobile apps RSL15 central for iOS® and Android™ and RSL FOTA for iOS and Android.
To get started with RSL15, download the SDK components: RSL15 documentation package, onsemi IDE installer, and RSL15 firmware package.
