Octal NOR

W35T Octal NOR Flash Achieves 400MB/s with JEDEC xSPI Interface

Built on Winbond’s advanced 58nm process, the W35T Octal NOR utilizes the JEDEC xSPI interface to achieve a continuous read throughput of 400MB/s, five times faster than standard W25Q QSPI NOR. This exceptional speed, powered by Octal DDR transfer rates up to 200MHz, delivers the industry’s highest synchronous 8-bit bandwidth, making it the ideal choice for instant-on and eXecute-in-Place (XiP) operations in next-generation automotive, industrial, and IoT applications.

To ensure robust signal integrity during demanding high-speed operations (>133MHz), the W35T Octal NOR integrates a dedicated Data Strobe (/DS) pin for precise output validation and synchronization. Despite its advanced capabilities, the series maintains a low signal count and backward compatibility with legacy x1 SPI systems, offering a seamless and efficient migration path for system upgrades without compromising on endurance or reliability.

Ultra-low power consumption

Engineered for superior efficiency, the W35T Octal NOR delivers up to 25% lower current in Standby and Deep Power-Down modes compared to leading competitors. Additionally, it features a dedicated /BUSY output pin that replaces inefficient software polling, allowing direct status monitoring. By minimizing both memory power draw and SoC workload, the W35T significantly extends battery life and optimizes overall system performance.

Enhanced data integrity

The W35T Octal NOR ensures total data fidelity by integrating Built-in ECC for automatic error correction, CRC-at-Rest for storage integrity, and CRC-in-Transit for secure transmission. This triple protection guarantees data accuracy both within the memory array and during high-speed communication with the SoC.

Automotive safety and reliability

With ISO26262 ASIL-D certification and AEC-Q100 Grade 1 qualification, the W35T guarantees reliable operation from -40°C to +125°C.

The W35T Octal NOR unites 400MB/s high-speed performance, comprehensive functional safety, and ultra-low power efficiency. This all-in-one solution empowers developers to meet the evolving demands of automotive and smart industrial applications, ensuring both superior performance and long-term reliability.
