Arm Demonstrates New IoT Test Chip and Board

Arm, in collaboration with Samsung Foundry, Cadence, and Sondrel, demonstrated the first 28nm fully-depleted silicon-on-insulator (FD-SOI) embedded, MagnetoResistive Random Access Memory (eMRAM) IoT test chip and development board, at the Samsung Foundry Forum.

The Musca-S1 is designed to offer more choice to IoT designers in their system-on-chip (SoC) development journey. With this, the designers can now easily implement more secure, holistic IoT solutions, enabling them to focus more on core product differentiation and accelerating time-to-market.

“The promise of a world transformed by a trillion connected devices is not far in the future, but for IoT devices to scale we must continue to put a range of technology options in front of designers to test and evaluate,”, the company said.

Like the previous Musca solutions, the Musca-S1 test chip board consists of testing and evaluation of new eMRAM technology for reliable, low-power and secure device development through secure memory implementation. eMRAM technology offers advantages over traditional embedded flash (eFlash) memory technology, as it can easily scale below 40nm process technology, giving SoC designers more flexibility to scale their memory needs based on the memory and power requirements of various use-cases.

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. And for the first time on Samsung Foundry silicon, designers will have the opportunity to run Arm Mbed OS as well as test device and data management capabilities using the Arm Pelion IoT platform.

By combining Arm IP and software solutions on a single board, IoT designers can test and evaluate Arm’s end-to-end secure IoT solution, showcasing highly energy-efficient and secure IoT at scale. Additionally, the Musca-S1 test chip board can further reduce costs and time-to-market by giving designers the flexibility to repurpose the reference design for future products.

Gus Yeung, VP, GM and Fellow, Physical Design Group, Arm added, “This collaboration has yielded a true end-to-end solution that ensures IoT designers can prototype their product designs from device-to-data security.”

The Main Features of the Musca-S1 test chip and Development Board include:

  • Has achieved PSA Certified Level 1 certification and brings together key components of the Arm IoT security portfolio including Arm CryptoCell-300 Family, Arm Coresight, Arm TrustZone, and Trusted Firmware-M (TF-M).
  • Powered by Arm Cortex-M33cores, built with Arm Corstone-200 secure foundation IP and hardware verified using Arm Keil MDK and ULINK-Plus probe.
  • Utilizes Sondrel’s design services to accelerate development schedules for designers.
  • Reduces design risks using digital implementation, signoff and verification flow and standards-based IP from Cadence.


The Musca-S1 test chip and development board is on display at Samsung Foundry Forum North America in San Jose, CA as part of an air sensor IoT application demo, featuring the device and data management capabilities of the Arm Pelion IoT platform.

The Musca-S1 will be available in limited quantities in Q3 2019, and is targeted for loan to customers in Q4 2019.
