Description

Introduction:
Winbond's W25Q256JW is a 256M-bit Serial Flash memory that offers a robust storage solution for systems with limited space, pins, and power. Ideal for applications including code shadowing to RAM, implementing code directly from Dual/Quad SPI (XIP), and for storing voice, text, and data, this device operates with high efficiency on a single 1.7V to 1.95V power supply, with power-down current consumption as low as 1µA.

Function & Applications:
The W25Q256JW provides vast flexibility in terms of data management, allowing up to 256 bytes to be programmed at a time with its information array organized into 131,072 programmable pages of 256-bytes each. This feature enables greater adaptability in scenarios needing various levels of data and parameter storage. The device is ideal for all sectors, including automotive and industrial applications, making it a go-to solution for diverse requirements.

Performance Parameters:
Operating at SPI clock frequencies of up to 133MHz, W25Q256JW supports an equivalent clock rate of 532MHz when using Quad I/O, outperforming standard Asynchronous 8 and 16-bit Parallel Flash memories. The durability is reflected in its minimum 100K Program-Erase cycles and more than 20-year data retention potential. It also demonstrates flexibility through its Uniform Sector/Block Erase architecture.

Package Types, Interface & Pin Configuration:
W25Q256JW is offered in different space-saving packages including 8-pad WSON 6x5-mm / 8x6-mm, 16-pin SOIC 300-mil (additional /RESET pin), 24-ball TFBGA 8x6-mm, 32-ball WLCSP. It supports the standard Serial Peripheral Interface (SPI), Dual and Quad I/O SPI, enabling smooth and secure data transfer.

Reliability & Lifespan:
The W25Q256JW ensures long-term reliability with its low power consumption, wide temperature range performance from -40℃ to +105℃ (2), and extensive data retention lifespan exceeding 20 years. It also encompasses a range of advanced security features such as power supply lock-down, OTP protection, and a unique 64-Bit ID for each device, solidifying its standing as a dependable data storage solution.

Standards & Certifications:
In aligning with industry standards, the W25Q256JW supports JEDEC standard manufacturer and device ID and SFDP Register. The product line leads the Serial Flash Market in unit sales and revenue, with Winbond's TS16949 certified AEC-Q100 qualified memories now supporting automotive applications.

Application Cases & Reference Designs:
In automotive applications, the W25Q256JW can significantly enhance digital displays in dashboards, providing improved safety and rich detail about the vehicle's status. Advanced applications, such as comfort, entertainment, and navigation systems, also benefit from W25Q256JW's high-density data storage and quick access times, proving this device to be a powerful asset in modern car manufacturing.
