W75F Secure Memory Element

W75F Secure Flash Solution is the first secure flash memory device to gain a Common Criteria (CC) EAL 5+ certificate. W75F enables secure eXecute-in-Place (XiP) and protects confidentiality and integrity of code / data in IoT devices. Application usage case include, but not limited to integrated UICC, integrated Secure Element, Artificial Intelligence (AI) platforms, integrated Hardware Security Modules (HSM) for automotive subsystems. The W75F provides the industry’s most secure external storage for code and data. It offers a dependable solution for manufacturers of connected devices who want to defend their products against threats such as replay, roll-back, man-in-the-middle, sniffing, side-channel and fault injection attacks. 

In 2020, W75F has achieved PSA Certified™ Level 2 ready in the PSA Certified independent security assurance scheme, also obtained ISO 26262 ASIL-D ready and SESIP Level 3 certificate with physical and software attacker resistance.

With PSA Certified™ Level 2 ready and the certificates aforementioned, W75F not only can provide a secure, certifiable, and flexible memory sub-system complementary to Arm®v8-M architecture-based systems, but also can ensure the security for IoT, automotive and Artificial Intelligence (AI) platforms. This enables SoC and MCU vendors to design secure and certifiable solutions while expediting time to market.
