System Architecture
The "Detailed Block Diagram of the RSL15 System" figure shows a detailed block diagram of the RSL15 system.
RSL15 is based around four key components:
- The Arm Cortex-M33 processor: A 32-bit core for real-time applications, specifically developed to enable high-performance low-cost platforms for a broad range of low-power applications. This processor is tightly integrated with the TrustZone Armv8-M security extensions, and is used to provide secure general-purpose processing and control of the RSL15 system’s components, including the RF front-end and Bluetooth baseband.
- TrustZone® Arm CryptoCell™-312: Provides a comprehensive security solution, with features protecting the authenticity, integrity and confidentiality of code and data, along with cryptographic hardware services, TRNG, and lifecycle state management.
- Radio Frequency Front-End: Based on a 2.4 GHz RF transceiver, the radio frequency front-end (RFFE) implements the physical layer of the Bluetooth Low Energy technology standard, and can be used to implement the RF layer of other standard and custom protocols.
- Bluetooth Protocol Baseband Hardware: Bluetooth low energy technology compliant, including support for all mandatory and optional features of the Bluetooth core 5.2 technology release, and compliance with the Blutetooth 5.2 core specification.
