Product Summary

In recent years, the scaling of NOR flash memory has been reaching its limits, and declining cost efficiency has become a particular issue for memory capacities of 512 Mbit and above, particularly for automotive and industrial equipment.

To solve this problem, Winbond has developed the new OctalNAND.

Winbond's OctalNAND products, the world's first NAND Flash memory with an octal interface, provide high-performance code storage Flash memory for general electronic devices as well as automotive and industrial applications that require high reliability.

Product features

• High-speed read (up to 240MB/sec)
• High durability (endurance 100,000 times, data retention 10 years)
• Long-term supply (46nm single-level cell NAND process)
• High-capacity flash for code storage
• Pin compatible with Octal NOR Flash

Advantages of Winbond Octal NAND Flash

<Evolutionary steps of flash memory>

Winbond's Octal NAND Flash supports high densities of over 1Gbit and achieves high-speed readout with an industry-first x8 interface.

This provides automotive and industrial equipment manufacturers with a cost-effective alternative to expensive NOR Flash, providing high-density code storage.

This is where Octal NAND has a significant advantage, especially since NOR Flash has difficulty scaling at densities above 512Mbit.

≪OctalNAND has the highest read throughput performance among embedded NAND flash≫

The first product equipped with the new interface, the W35N01JW (1Gbit), achieves a maximum sequential read throughput of 240Mb/s, approximately three times faster than the previous high-performance W25-JW quad-serial NAND Flash family.

In addition, Octal NAND Flash boasts erase speeds up to 400 times faster and write speeds up to 50 times faster than serial NOR Flash, making it an ideal solution for OTA (Over-The-Air) updates.

The W35N-JW Octal NAND Flash is manufactured on Winbond's proven 46nm Single-Level Cell (SLC) NAND process, providing excellent data integrity and over 10 years of data retention performance.

Additionally, it is rated for 100,000 program/erase cycles. It is compatible with 10Gb/s and provides the high durability and reliability required for mission-critical automotive and industrial applications.
