W25Q40CLSNIG in Winbond W25Q SPI NOR Flash Family

The W25Q40CLSNIG is part of Winbond's Serial Multi-I/O SpiFlash memory family, providing a space-efficient 4M-bit NOR Flash solution. Manufactured using Winbond's high-performance 2.5V to 3.6V technology, these components support Standard, Dual, and Quad SPI interfaces. They are designed for embedded systems requiring reliable non-volatile storage with high throughput, often serving as a code execution or data logging medium for microcontrollers with limited internal memory resources.

Variants in This Sub-Family

Variants within the W25Q40CLSNIG sub-family primarily differ in their packaging and delivery format rather than electrical characteristics. The 'SNIG' suffix denotes the 150-mil 8-pin SOIC package with a lead-free, halogen-free finish. Ordering codes ending in 'TR' indicate Tape and Reel packaging for automated pick-and-place assembly, whereas the standard part is typically supplied in tubes. Functional specifications for voltage range and clock speed remain identical across these ordering variants.
