NXP Semiconductors has announced that its LPC55S16 MCU has been awarded Level 2 certifications by both the PSA Certified scheme co-developed by Arm and the GlobalPlatform Security Evaluation Standard for IoT Platforms (SESIP) using the secure protection profile for embedded processors. With fast-expanding IoT and Industrial edge applications, device security and data protection become paramount, says NXP.
The LPC55S16 MCU is a member of NXP’s general purpose LPC5500 MCU series based on the Arm® Cortex®-M33 core. This series offers performance efficiency leveraging 40-nm NVM process technology, advanced security, and mixed-signal capabilities.
Both the SESIP and PSA Certified testing and certifications were done by Brightsight, one of the best-known independent security evaluation laboratories. The LPC55S16 MCU achieved PSA Certified Level 2 that is based on a comprehensive assurance framework to showcase robustness of the security, enabling device manufacturers to reduce additional security testing and improve time to market. It uses a 25-day time-boxed laboratory evaluation against the PSA Root of Trust (PSA-RoT) security claims to demonstrate that the device can protect against scalable software attacks.
To achieve GlobalPlatform SESIP 2, the LPC55S16 MCU underwent source code analysis and penetration testing issued by Brightsight and was validated by another independent certification body. SESIP certification helps assure product security claims are tested and verified, and provides evidence of the LPC55S16 MCU’s resistance to basic attack potential. SESIP allows for customers to re-use the LPC55S16 MCU validation results in the certification process for their end applications.
The LPC55S16 MCU integrated security features include:
- Arm TrustZone technology, which enables system-wide software protection with the ability to securely isolate peripherals to reduce the risk of attack on critical components
- AES-256 accelerator provides confidentiality and secure hash algorithm (SHA2) accelerator provides integrity of secure communications and secure boot
- PRINCE module offers real-time encryption and decryption of the on-chip flash to provide both secure storage of data and asset protection of software intellectual property (IP)
- CASPER Crypto co-processor enables hardware acceleration of various asymmetric cryptographic algorithms to establish secure connections
- Physical Unclonable Function (PUF) uses dedicated on-chip SRAM to construct unique device root keys (64 to 4096 bits) for secure storage
- 128-bit unique device serial number for identification (UUID)
- True Random Number Generator (TRNG)
- Code watchdog enables integrity checking of execution flow of the firmware
- Debug authentication protocol for secure debugging
The LPC55S16 MCU is part of the Certified EdgeLock Assurance program. The LPC55S16 MCU family is available now with a suggested resale price starting at $1.54 for 10,000-unit quantities.
