New TrustZone Empowered Microcontroller released, Focusing on IoT Security

The rise of the internet of things era has increased awareness for the integration of the physical world into digital systems. While the digitization of our everyday lives led to efficiency improvements and economic benefits, it has also caused pressure on systems designers who are now required to come up with innovative IoT products capable of performing secure connection and data exchange while maintaining low power consumption.

The NuMicro M2351 microcontroller series is powered by Arm Cortex-M23 core and operates at up to 64 MHz frequency, with up to 512 Kbytes Flash memory and up to 96 Kbytes SRAM. The NuMicro M2351 series is embedded with TrustZone for Armv8-M architecture and Arm PSA with Nuvoton Secure Microcontroller Platform (NuSMP) Supported, which elevates the traditional firmware security to a new level of robust software security.

TrustZone for Armv8-M and Nuvoton Security Functions Empowered

Arm TrustZone technology is a System on Chip (SoC) and CPU system-wide approach to security. In addition to the firmware-level security, the NuMicro M2351 series offers a more enhanced software-level security for more robust security and greater power efficiency. Furthermore, the TrustZone architecture could benefit the collaborative software development business model with rapid development and robust intellectual property protection.

Power Management Technology for IoT Innovation

In addition to security, power consumption is also critical for IoT applications. M2351 Series offers multiple power modes for more efficient power management. Regarding the power consumption of M2351 series, the normal run mode consumes 97 μA/MHz in LDO mode and 45 μA/MHz in DC-DC mode. The current consumption of stand-by power down mode is 2.8 μA and the deep power-down mode without VBAT is less than 2μA.
