W25Q64JVSSIQ
Overview
The W25Q64JVSSIQ is a 64Mbit (8MB) Serial Flash memory supporting SPI, Dual SPI, and Quad SPI interfaces for high-performance data access. It operates on a 2.7V to 3.6V supply range and features a high-speed clock frequency of 133 MHz, making it suitable for systems that require fast boot times or Execute-in-Place (XiP) functionality. This specific variant comes in an 8-pin SOIC package and includes a fixed Quad Enable (QE) bit for immediate Quad I/O operation.
Why Choose This Part
It offers a low power-down current of 15uA and an active read current of 8mA at 50MHz, balancing performance with energy efficiency. The Quad SPI interface significantly increases throughput compared to standard serial flash, while the 208-mil SOIC-8 package provides a standard footprint for automated PCB assembly.
Applications
Key Specifications
Getting Started
To interface with this part, configure your MCU SPI peripheral for Mode 0 or Mode 3 and ensure the VDD is within the 2.7V to 3.6V range. Developers can use standard libraries like the Arduino ESP32 core or STM32 HAL SPI drivers to perform page programs (256 bytes) and sector erases (4KB).
