New ASIL-D Certificate Boost Safety and Security Credentials of Winbond’s W75F Secure Memory Element

November 16, 2020 Tiera Oliver

Winbond Electronics Corporation announced that its W75F, the industry’s first Secure Flash memory device with Common Criteria EAL5+ certificate, has now achieved the ISO26262 ASIL Grade D safety certification.

For the automotive market, the W75F Secure Memory is compliant with the AEC-Q100 and is now certified ASIL-D. The W75F device provides fault detection capabilities covering more than 99.9% of failures, per the company, ranging from flash array cells, through the physical interface, and all the way to the host. The safety rating for the W75F surpasses that of internal embedded Flash memories while offering more storage capacity that can be scaled up to even higher densities.

The W75F has also been certified with the Security Evaluation Scheme for IoT Platforms (SESIP) scheme for IoT and smart connected devices up to Level 3 with physical attacker.

The W75F Secure Memory is an ideal secure external Flash device for code and data storage. It offers a solution for manufacturers of connected systems, which want to defend their products against threats such as replay, rollback, man-in-the-middle, sniffing, side-channel, and fault injection attacks.

It is available in densities of 4Mb, 16Mb and 32Mb and is available in industry-standard SOP16, QFN32, and WLCSP packages.

Key features of the W75F include:

  • Secure eXecute-in-Place (XiP)
  • Tamper-resistant
  • Code and data confidentiality and integrity
  • Mutual authentication with SoC
  • Shared memory architecture for multiple domains
  • 21MB/s secured and authenticated throughput
  • 100,000 program/erase cycles
  • 20-year data retention
