W25Q40CLSNIG TR
Overview
The W25Q40CLSNIG is a 4Mbit (512K x 8) Serial Flash memory device that supports Standard, Dual, and Quad SPI interfaces. It operates on a single 2.3V to 3.6V supply and features a high-performance 104MHz clock frequency, providing efficient data throughput for embedded systems. With its 1uA power-down current and small 8-SOIC footprint, it is optimized for space-constrained and battery-powered applications.
Why Choose This Part
The W25Q40CLSNIG offers Quad SPI performance with 104MHz clock speeds, enabling fast data access and execution-in-place (XIP) capabilities. Its ultra-low power consumption of 1mA active and 1uA in power-down mode extends battery life in mobile designs. Additionally, the inclusion of a 64-bit Unique Serial Number facilitates device identification and simple security tracking.
Applications
Key Specifications
Getting Started
To integrate this part, configure your MCU SPI peripheral for Mode 0 (0,0) or Mode 3 (1,1) operation at up to 104MHz. Use standard JEDEC commands for read/write operations or leverage existing libraries like the Arduino SerialFlash or manufacturer-provided C drivers. Ensure a 0.1uF decoupling capacitor is placed close to the VCC pin for stable operation across the 2.3V to 3.6V range.
