Revolutionizing Automotive Security with Winbond's W77T Memory

Revolutionary Introduction of Winbond's W77T Secure Flash Memory

Leading global semiconductor memory solutions provider Winbond Electronics Corporation has unveiled its latest innovation: the TrustME W77T Secure Flash family. This groundbreaking product is engineered specifically for the automotive sector, catering to the rising demands of software-defined vehicles (SDVs) and complex electronic systems. With its compliance to several automotive standards, including ISO26262 ASIL-D, ISO21434 Certification, and UNECE WP.29, the W77T is set to redefine safety and performance standards for connected and autonomous vehicles.

High Performance Meets Strict Security Standards

The W77T is not just an ordinary flash memory; it operates at an impressive 200MHz Double Transfer Rate (DTR) using an industry-standard Octal/xSPI interface. This allows it to achieve a remarkable read bandwidth of up to 400MB/s. Such speed is essential for automotive System-on-Chip (SoC) designs where rapid boot times and powerful processing capabilities are critical. The memory is available in various densities, ranging from 64Mb to 1Gb, and offers diverse packaging options, including TFBGA, SOIC, and WSON packages. It also includes advanced Replay Protected Monotonic Counters (RPMC), ensuring a secure implementation.

Exceptional Security Features Tailored for Automotive Applications

Winbond's W77T is built with robust security features that help to fortify the vehicle's safety and integrity. The Secure Flash family incorporates Post-Quantum Cryptography (PQC) and adheres to NIST 800-193 compliant firmware resiliency. This ensures that not only is the memory secure against current threats, but also future-proof against evolving cyber challenges. Furthermore, the W77T supports remote attestation through LMS-OTS, facilitating secure supply chain processes.

In-Depth Features of the W77T Secure Flash

One of the most compelling aspects of the W77T Secure Flash is its extensive suite of features focused on security:

• Code and Data Protection: The W77T employs advanced mechanisms that shield both code and data, making unauthorized access incredibly difficult. Its Root of Trust implementation aligns with the TCG DICE attestation protocol.
• Authentication: Stringent authentication processes are in place, ensuring that only verified software and personnel gain access to the device.
• Secure Software Updates: The device permits remote software updates while preventing rollback attacks. Utilizing Leighton-Micali Signature (LMS) algorithms, the authenticity of updated software is guaranteed, giving users peace of mind.
• Platform Resiliency: Following the best practices outlined in NIST 800-193, the W77T detects any unauthorized code changes, allowing automatic recovery to a secure state.
• Secure Supply Chain: The integrity of the flash content is maintained throughout the entire supply chain. The W77T implements advanced LMS-OTS for secure transportation and configuration.

Winbond's Commitment to Innovation and Security

As the market for software-defined vehicles grows, Winbond recognizes the urgent need for high-performance and secure solutions. "We are excited to launch our most advanced Secure Flash product family, the W77T Secure Flash," a company representative stated. Winbond aims to empower automotive manufacturers with tools that meet the stringent reliability and security demands of the industry.

The W77T samples—available at densities of 256Mb, 512Mb, and 1Gb—will soon be accompanied by additional offerings in the form of 64Mb and 128Mb devices. Winbond is dedicated to evolving with the industry's needs and ensuring the highest standards of safety in automotive flash memory solutions.
