W25Q128JVEJQ

Introduction

The W25Q128JV Serial NOR Flash memory developed by Winbond is a 128M-bit storage solution designed for systems with limited space, pins, and power requirements. It offers superior flexibility and performance compared to ordinary Serial Flash devices, making it an ideal choice for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing voice, text, and data. Operating on a single 2.7V to 3.6V power supply, the device consumes as low as 1µA for power-down and is available in space-saving packages.

Function & Applications

The W25Q128JV is particularly beneficial for applications that require data and parameter storage due to its small 4KB sectors, which allow for enhanced flexibility. The device supports various interfaces, such as standard SPI, Dual I/O, and Quad I/O SPI, along with clock frequencies up to 133MHz. With Fast Read Dual/Quad I/O capabilities, these transfer rates can surpass asynchronous 8 and 16-bit Parallel Flash memories in terms of performance.

Some key applications for the W25Q128JV include:

1. Automotive applications, such as dashboards and center consoles
2. Industrial equipment
3. Mobile and handheld devices
