The world’s first x8 Octal interface for NAND flash memory, Winbond’s OctalNAND flash enables automotive and industrial manufacturers to provide code storage in high density without having to pay a premium for NOR flash, a fast memory technology which scales poorly at densities above 512Mbits.
The first Winbond product to include the new interface, the 1Gbit W35N01JW, offers a maximum continuous Read throughput of 240MB/s, three times faster than the earlier high-performance W25N-JW QspiNAND Flash family.
The OctalNAND flash offers partial compatibility with Octal NOR flash, which makes it easier to replace NOR flash in existing designs.
Manufactured in Winbond’s proven 46nm Single Level Cell (SLC) NAND fabrication process, the W35N-JW OctalNAND flash offers excellent data integrity and more than ten years’ data retention. It is specified to perform more than 100,000 Program/Erase cycles, providing the high level of endurance and reliability required in mission-critical automotive and industrial applications, including graphics displays and advanced driver-assistance systems (ADAS) in which the boot code size is often higher than 512 Mbits, NOR flash is reaching its limitations in scale.
