Winbond Electronics, a global supplier of semiconductor memory solutions, has announced the new OctalNAND/W35N-JW family.

In recent years, scaling of NOR flash memory is approaching its limits, and in the capacity band of 512 Mbits and above, the decline in cost efficiency has become a particular problem, especially for automotive and industrial equipment. Winbond newly developed OctalNAND to solve this problem. Winbond's OctalNAND, the world's first NAND flash memory with an octal interface, provides customers with large capacity code storage at no extra cost.

The OctalNAND/W35N-JW family is manufactured on Winbond's 46nm single-level cell (SLC) NAND process to achieve the high endurance and reliability required for robust automotive and industrial applications. provides 10-year data retention and 100,000 program/erase cycles.

The 1Gbit W35N01JW is the world's first NAND product with an octal interface. The continuous read throughput is up to 240Mbytes/sec, which is three times faster than the existing high-performance serial NAND flash memory/W25N-JW family. It is also 1.5 times faster than the dual quad serial NAND flash memory/W72N-JW family.

Contributes to fast boot code execution and reduced BOM cost

Applications such as automotive graphic displays and ADAS (Advanced Driver Assistance Systems) often have bootcode sizes of 512Mbits or more. Traditionally, NOR flash memory has been used due to its high reliability and fast read throughput. However, NOR flash memory is reaching its limits in terms of scaling, and the die size is particularly large at densities of 512 Mbits and above, resulting in high cost.

NAND flash memory excels in terms of scaling and is best suited for 1 Gbit and higher capacities. However, conventional NAND flash memory has the disadvantage of slow read throughput.

Yudai Kaminaga, Deputy General Manager, Flash Memory Group, Marketing & FAE Department, Winbond Electronics Co., Ltd. "Winbond's new OctalNAND delivers 240MBytes/sec read throughput in the 1-4Gbit density range. This will enable automotive and industrial customers to choose Octal NOR Flash memory for comparable performance." You will be able to enjoy it at a fraction of the cost.”

Winbond's OctalNAND/W35N-JW family is compatible with Octal NOR Flash memory, making it an easy replacement. In addition, it is footprint compatible with serial NOR flash memory and fully pin compatible with Xccela™ flash memory and octal NOR flash memory currently on the market. Leading automotive customers can replace Octal NOR Flash memory with Winbond's OctalNAND/W35N-JW family in new designs to achieve faster boot times and lower BOM costs.

The OctalNAND/W35N-JW family includes a reset pin to support customer approaches to automotive safety compliance. This reset pin is compatible with equivalent serial/octal NOR flash memory pinouts.
