Musca-S1 test chip demonstrates a combination of on-chip power control, Samsung Foundry’s Reverse Body Biasing (RBB) and eMRAM non-volatile memory power shutdown, allowing for testing and evaluation of new classes of highly energy-efficient, controlled IoT devices.īy combining Arm IP and software solutions on a single board, IoT designers can test and evaluate Arm end-to-end secure IoT solution, showcasing highly energy-efficient and secure IoT at scale. The Musca-S1 dual Arm Cortex-M33 test chip board architecture integrates the recommendations of Platform Security Architecture, (PSA) using the same subsystem as Musca-A, but with the addition of dual embedded MagnetoResistive Random Access Memory (eMRAM) and SRAM on-chip secure memory subsystemsīased on Arm’s Corstone-200 pre-verified subsystem with dual Cortex-M33 processor cores, AMBA AHB5/Trust Zone dual eMRAM and SRAM code memory subsystems, Samsung analogue IPs for control, Cadence and Arm peripheral interface IPs for extended network and cellular connectivity, Musca-S1 provides a series of silicon-proven insights for secure and energy-efficient IoT design on Samsung 28FDS FDSOI silicon. Recognizing this need Arm and Samsung Foundry collaborated to create the industry’s 1st PSA Certified Arm-based Smart IoT Device demonstrator called Musca-S1 enabling secure eMRAM-enabled Root of Trust (RoT) and secure Root of Execution (RoE) IoT Device services. The digital transformation is underway and driving the need for a new generation of Smart IoT Devices that are both secure and energy-efficient and the foundation to enabling our secure connected world.
