The Winbond W25N04KVZEIRS is a 4Gbit serial SLC NAND Flash memory from Winbond’s W25N KV-series QspiNAND family. It pairs the high density and low cost of NAND technology with a simple SPI-compatible serial interface, making it ideal for code storage and data logging in space-constrained, pin-limited embedded designs. The device delivers 4Gb (512M x 8) of storage in a compact WSON-8 (8x6mm) surface-mount package and includes integrated on-chip 8-bit ECC to maintain data integrity over the device lifetime.
Built on Winbond’s QspiNAND architecture, the W25N04KVZEIRS supports Standard SPI, Dual SPI, and Quad SPI (x1/x2/x4) I/O modes at clock frequencies up to 104 MHz, and offers a Sequential Read mode for efficient access across the array. As an SLC NAND device it provides higher endurance and reliability than equivalent MLC/TLC parts, which is why it is favored in industrial and embedded applications.
Pacific Component Xchange is an independent distributor specializing in hard-to-find, allocated, and obsolete memory. The W25N04KVZEIRS can be difficult to secure through authorized channels, and we currently hold available inventory to support your production and repair needs. Every device is screened for authenticity and quality to protect your build against counterfeit risk, and we ship globally with the documentation your supply chain requires.
Because this is a Request-For-Quote (RFQ) item, pricing is provided per order based on quantity, date code, and lead-time requirements. Submit an RFQ today and our sourcing team will respond promptly with current availability and a firm quote.
It is a 4Gbit (512M x 8) single-level-cell (SLC) QSPI NAND Flash memory from Winbond's W25N KV-series, housed in a WSON-8 (8x6mm) surface-mount package and supporting Standard, Dual, and Quad SPI operation. The base ordering part number is W25N04KVZEIR (Industrial grade).
The device provides 4 Gbit (512M-Byte) of storage organized as 512M x 8, arranged in programmable pages of 2,048 bytes plus a 128-byte spare area (2,048B + 128B page).
It supports Standard SPI, Dual SPI, and Quad SPI (x1/x2/x4 I/O) at a maximum clock frequency of 104 MHz, with a Sequential Read mode for efficient access across the entire array.
It comes in a WSON-8 (8x6mm) package with exposed pad and operates over the industrial temperature range of -40 C to +85 C at a 2.7 V to 3.6 V supply.
Yes. As a Winbond QspiNAND device it integrates on-chip 8-bit hardware ECC (Error Correcting Code) to detect and correct bit errors and maintain data integrity over the device lifetime.
