New automotive-qualified secure flash memory

Winbond Electronics Corporation has unveiled the TrustME W77T Secure Flash family, specifically designed for the automotive industry. This ISO26262 ASIL-D Ready, ISO21434 Certified, UNECE WP.29 and TISAX compliant Secure Flash is tailored to satisfy the demands of emerging automotive applications, such as software-defined vehicles (SDVs) and E/E systems, delivering advanced protection for connected and autonomous vehicles.

Operating at a 200MHz Double Transfer Rate (DTR) on the industry-standard Octal/xSPI interface, the family provides a read bandwidth of up to 400MB/s, making it ideal for automotive SoC designs that need fast boot times and high-performance processing capabilities. Obtainable in a range of densities from 64Mb to 1Gb, the family is offered in TFBGA (Octal SPI), SOIC (Quad SPI) and WSON (Quad SPI) packages. It also features extended Replay Protected Monotonic Counters (RPMC) with eight counters for PC-based implementation. Other advanced capabilities include JEDEC SPI CRC, JEDEC xSPI compatible interface, and ECC, and it is manufactured in its security-certified fabrication facility to ensure a secure supply chain.

As part of the company's TrustME Secure Flash family, the W77T provides robust security features, including Post-Quantum Cryptography (PQC) capabilities for the security engine, NIST 800-193 compliant firmware resiliency, LMS-OTS (NIST-800-208) based remote attestation for secure supply chain, Common Criteria, ISO21434, FIPS 140-3 certification and ISO26262 Functional Safety requirements, ensuring vehicle safety, performance, and integrity.

The W77T Secure Flash is backwards compatible with the popular W25Q NOR Flash and W77Q Secure Flash family and comes with an arsenal of features designed to ensure Automotive security.

"We are excited to launch our most advanced Secure Flash product family- W77T Secure Flash," says Winbond, emphasizing our commitment to providing safety and security in automotive flash components. "As E/E architectures evolve to support software-defined vehicle designs, security and high reliability are top priorities for designers and vehicle manufacturers. The market will demand a high-performing, feature-rich, yet highly secure vehicle. The W77T is an effective solution for meeting these challenges and driving innovation in the automotive industry."

The 256Mb, 512Mb and 1Gb samples are available now, with 64Mb, 128Mb devices available soon.
