Winbond NOR 4 MB SPI Flash Memory 8-Pin USON W25X40CLUXIG

Winbond W25X40CLUXIG is a NOR flash memory device providing 4 MB (512K-byte) of non-volatile serial memory in an 8-pin USON surface-mount package. It operates with a high-speed SPI interface featuring single and dual output modes, enabling data transfers up to 208 M-bits per second with a maximum clock speed of 104 MHz. The memory architecture supports page programming up to 256 bytes and offers uniform erasable sectors of 4KB, 32KB, and 64KB sizes, allowing flexible data management and efficient use of storage space.

This memory device operates over a wide temperature range from -40°C to 85°C, making it suitable for harsh industrial and automotive environments. The device’s supply voltage range is between 2.3 V and 3.6 V, ensuring compatibility with varying power systems. Its compact USON package measures 2.1 mm by 2.1 mm with a height of only 550 μm, ideal for space-constrained applications.

The memory supports both standard SPI signals (CLK, /CS, DI, DO, /WP, /Hold) and dual SPI modes (CLK, /CS, IO0, IO1, /WP, /Hold), which enhance throughput and communication efficiency for embedded systems. Its low instruction overhead and continuous read capabilities facilitate execute-in-place (XIP) operations, reducing latency in memory access.

Winbond W25X40CLUXIG is widely applied in consumer electronics, automotive systems, industrial control units, telecommunications equipment, and other applications requiring reliable, high-performance serial flash memory. Its durability and uniform sector erase architecture provide consistent performance for both code execution and data storage.
