Winbond Launches Advanced W77T Secure Flash Memory for Automotive Applications

Winbond Unveils New Automotive-qualified W77T Secure Flash Memory

Winbond Electronics Corporation, a prominent player in the semiconductor memory industry, has introduced its latest innovation—the W77T Secure Flash memory, designed specifically for the automotive sector. Recognizing the rapid advancements in automotive technology, particularly in connected and autonomous vehicles, Winbond's W77T aims to meet the robust security and performance requirements demanded by software-defined vehicles (SDVs) and electronic/electrical (E/E) systems.

Key Features of the W77T Secure Flash Memory

This cutting-edge product boasts compliance with ISO26262 ASIL-D, ISO21434, UNECE WP.29, and TISAX standards, indicating its ability to function safely in critical automotive applications. Operating at a speed of 200MHz with a Double Transfer Rate (DTR) via the industry-standard Octal/xSPI interface, the W77T provides an impressive read bandwidth of up to 400MB/s. Such high speed is particularly beneficial for automotive System-on-Chip (SoC) designs, which require quick boot times and high-performance processing capabilities.

With memory densities ranging from 64Mb to 1Gb, the W77T is available in various packaging options, including TFBGA (Octal SPI), SOIC (Quad SPI), and WSON (Quad SPI). This versatility allows manufacturers to choose the suitable variant that aligns with their specific applications and design requirements.

Advanced Security Features

As part of the TrustME® Secure Flash family, the W77T integrates several advanced security features that protect both code and data against tampering. It is equipped with features such as:
- Post-Quantum Cryptography (PQC): A cutting-edge technology that ensures the highest levels of data protection against future threats.
- Firmware Resiliency: Compliant with NIST 800-193, the firmware provides robust protection against unauthorized changes, automatically detecting and recovering from potential attacks.
- Secure Software Updates: The W77T can facilitate remote and secure software updates with rollback protection, making certain that only legitimate updates are applied.
- Authentication Protocols: Stringent authentication measures are in place, allowing only approved software layers and actors to access the system, thereby reinforcing the integrity of vehicle operations.

Further enhancing its protective capabilities, the W77T utilizes the Leighton-Micali Signature (LMS) algorithms for software updates as recommended by the NIST Special Publication 800-208. This ensures that any software uploaded to the vehicle is both authentic and secure.

Ensuring Secure Supply Chains

Winbond's commitment to security extends to the entire supply chain. The W77T incorporates remote attestation mechanisms based on LMS-OTS (NIST 800-208) that prevent content tampering and misconfigurations that could occur during assembly and transportation phases. By ensuring the integrity and authenticity of the flash memory at every stage, Winbond significantly reduces the risks posed by cyber threats.

In a statement regarding the launch, Winbond highlighted the importance of security and reliability in automotive components, asserting, "As E/E architectures evolve to support cutting-edge vehicle designs, the demand for high performance and robust security has never been greater. The W77T Secure Flash addresses these challenges head-on."

Conclusion

With samples of the 256Mb, 512Mb, and 1Gb already available, and smaller variants such as the 64Mb and 128Mb expected shortly, Winbond is poised to make a significant impact on the automotive memory market.
