W25Q64JWSSIQ

Introduction:

The W25Q64JW by Winbond is a 64M-bit Serial Flash memory that is part of the company's 25Q series. It is specifically designed for systems with limited space, power, and pin capacity. The device is ideal for code shadowing to RAM, executing code from Dual/Quad SPI (XIP), as well as storing voice, text, and data. The W25Q64JW operates on a power supply between 1.7V and 1.95V, and its current consumption is as low as 1µA during power down. Furthermore, the components are offered in space-saving packages.

Function & Applications:

The W25Q64JW can store up to 64M-bit of information, arranged into 32,768 programmable pages, each containing 256 bytes. This capacity ensures its suitability for applications that require data and parameter storage including automotive, industrial, and digital display applications. Also, its advanced security features such as Software and Hardware Write-Protect and Special OTP protection makes it suitable for applications where data security is paramount.

Performance Parameters:

The device supports standard SPI, Dual/Quad output as well as Dual/Quad I/O SPI. SPI clock frequencies of up to 133MHz are supported, allowing equivalent clock rates of 532MHz for Quad I/O. It can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. The device has a 66MB/S continuous data transfer rate and a minimum of 100k Program-Erase cycles. Its data retention rate is over twenty years.
