New Tang M2351 Series
Leading the IoT Security Era with Arm PSA Level 2 Certification
The NuMicro® M2351 series from New Tang Technology, as one of the first microcontrollers based on the Arm Cortex®-M23 core, has achieved PSA Certified Level 2 and Functional API certification, meeting the stringent requirements for product/communication security in the IoT era and leading the IoT security era.
Arm PSA Certification: The Cornerstone of IoT Security
The Arm® Platform Security Architecture (PSA) certification is an IoT security framework launched by Arm, aimed at providing standardized security design guidelines and verification mechanisms for device manufacturers. This certification is divided into three levels, from basic threat analysis (Level 1) to advanced security feature verification (Level 3), progressively enhancing device security. The core goal of PSA certification is to help manufacturers achieve end-to-end security design at lower costs through open-source tools (such as Trusted Firmware-M) and standardized interfaces, covering the entire link from hardware and firmware to the cloud.
Hardware-Level Security Architecture Features of NuMicro® M2351 Series
-
Utilizes Arm TrustZone® technology to partition the chip into secure and non-secure zones, achieving hardware isolation and protecting sensitive data from software attacks.
-
Built-in encryption and decryption pin engine (AES/SHA/ECC, etc.), supports secure bootloader and tamper detection pins, ensuring the integrity of firmware and communication.
-
Incorporates New Tang’s patented key management unit, Keystore, which isolates MCU core and RAM access to keys, allowing for safer key storage and more effective data encryption and decryption processing.
-
Certified by ARM PSA Certified Level 2 and Functional API
Sharing Successful Applications of NuMicro® M2351 Series Products
-
Smart Meters and Energy Management
The M2351 series supports the AMI 2.0 international standard and has been applied in smart meters and DTU designs for power companies both domestically and internationally, enabling remote meter reading capabilities. Its security features, certified by Arm PSA Level 2, ensure the trustworthiness of equipment and communication chains in the power/energy industry.
