With SESIP level 2 certification, W77Q Secure Flash will provide connected devices a higher level of assurance by requiring a vulnerability analysis and actual penetration testing on IoT platform design systems using Secure Flash in compliance with security and functional safety standards simultaneously.

TAICHUNG, Taiwan—2022-5-31— Winbond Electronics Corporation, a leading global supplier of semiconductor memory solutions, today announced that the company’s TrustME ® W77Q Secure Flash has obtained Security Evaluation Scheme for IoT Platforms (SESIP) Level 2 with Physical Attacker Resistance Certification. This is the first certification using GlobalPlatform SESIP Profile for Secure External Memories, and NIST 8259A (IoT device cybersecurity capability core baseline). The certification also claims compliance to IEC 62443 (security for industrial automation and control systems). With the prestigious industry-recognized security certification, TrustME W77Q Secure Flash can satisfy the emerging demands in cybersecurity simultaneously in IoT applications.

The W77Q family has also been certified with the Common Criteria EAL2+, Functional safety ISO26262 ASIL-C level and FIPS 140-3 CAVP.

W77Q Secure Flash comes in densities of 16Mb, 32Mb, 64Mb and 128Mb, it operates at a frequency of 66MHz in Double Transfer Rate mode and 133MHz in Single Transfer Rate mode. It features standard single/dual/quad/QPI serial peripheral interface (SPI), as well as industry-standard packages and pin-outs to facilitate their uses as a drop-in replacement for non-secure SPI NOR Flash devices. W77Q Secure Flash is capable of retaining data for over 20 years and can perform 100,000 Program/Erase cycles with a wide operating temperature range of -40°C to 105°C.

Security Features

Complementary to the host chip, W77Q Secure Flash provides the security features of secure boot code storage and authentication, secure firmware update, remote attestation for building platform

Root of Trust and firmware resiliency. These outstanding security features are enabled by the below security functions from the perspectives of protection, detection, and recovery:

• Data confidentiality
• Data and command authentication
• Code integrity protection
• Replay protection
• Cryptographically secured write protection
• Secure code update with rollback protection
• DICE-like attestation mechanism
• Authenticated Watchdog Timer with an optional hardware reset output
• Secure firmware over-the-air update, via an end-to-end secure channel between an update
authority (a.k.a. OTA server) and the W77Q even when the host processor or SoC has been
compromised.

“We would like to congratulate GlobalPlatform Full Member Winbond for achieving SESIP Level 2 certification,” adds Ana Tavares Lattibeaudiere, Executive Director of GlobalPlatform. “SESIP is helping IoT product manufacturers, like Winbond, to comply with specific security requirements and regulations. Because the methodology is mappable to other evaluation methodologies, and compliant with many standards and regulations, it is reducing the complexity, cost and time-to-market for IoT stakeholders as we all work to bring greater trust to the IoT ecosystem.” “In the world of connected devices, security is becoming strategic for risk management, market differentiator and compliance. Many standards and regulations are emerging across regions and verticals. Standards like IEC 62443, NIST 8259A and others are looking to address core security functionality. SESIP has rapidly grown internationally as the recognized certification going beyond the security fragmentation. As an optimized version of CC applied to IoT market, SESIP is providing evidence of secure products by design. The proper protection of stored data is a key element of the overall security of devices.” says Carlos Serratos, Director of Strategy at SGS Brightsight. Carlos goes on to say, “SGS Brightsight congratulates Winbond with the successful certification of their W77Q16/32 Secure Flash Memory under SESIP and CC, an achievement on itself that gets enhanced for proving its readiness for applications in the scope of IEC 62443 and NIST 8259A. Glad to be the Winbond partner in its security journey!”
