Product Overview
The W25N04KVZEIR is a high-performance 4-Gbit serial SLC NAND Flash memory storage solution designed by Winbond Electronics. It provides an efficient, space-conscious alternative to traditional parallel NAND memory architectures, utilizing a versatile SpiFlash® interface that supports Standard, Dual, and Quad SPI operations. Running at clock frequencies up to 104 MHz, this chip delivers exceptionally high data transfer rates, backed by an advanced Continuous Read architecture that accelerates data access across page boundaries without delays. The device is manufactured using a reliable single-level cell (SLC) design structure, featuring integrated on-chip 1-bit ECC hardware engine modules. Housed in a space-optimized WSON-8(6x8mm) package, the provides robust reliability, high endurance, and fast write/erase speeds required by data-intensive network equipment, smart consumer products, and advanced storage expansion architectures.
Core Advantages
Massive Storage Density & Layout Efficiency
By packing a large 4Gb (512MB) capacity into a tiny WSON-8(6x8mm) layout, this chip dramatically slashes the PCB layout complexity and trace density required by traditional multi-pin parallel flash variants, making it a perfect match for ultra-compact systems.
Ultra-Fast High-Bandwidth SPI Throughput
Supporting standard Quad SPI operation speeds up to 104 MHz, the device delivers a continuous processing bandwidth equivalent to 416 Mbps. This ultra-fast pipeline supports fast code shadow-booting routines and real-time execution parameters.
Integrated On-Chip Hardware ECC
Features an onboard hardware Error Correction Code (ECC) execution block that autonomously manages 1-bit error corrections per 512 bytes of data. This eliminates computational overheads from the host processor while maximizing long-term non-volatile data persistence.
Robust Longevity & Endurance Profile
The industrial SLC (Single-Level Cell) formulation supports broad temperature operations and ensures a lifetime endurance performance of 60,000 Program/Erase cycles (typical). This provides stability for enterprise networking hardware or repetitive read/write operations.

Frequently Asked Questions
Q1: Is your stock of W25N04KVZEIR original and factory-new?
A: Yes, we provide 100% genuine and authentic Winbond components. All parts are completely new, unprogrammed factory stock with full batch numbers and traceable date codes.
Q2: What is the main structural benefit of the W25N04KVZEIR continuous read feature?
A: Winbond’s continuous read implementation allows the host to stream the entire 4Gb memory contents sequentially using a single read command. This avoids the latency delays required to manually switch page locations in typical serial NAND arrays.
Q3: Do I need to implement software ECC on our host microcontroller to use this component?
A: No, the W25N04KVZEIR features built-in hardware on-chip ECC logic. It automatically scans and fixes bit errors during flash execution, offloading the calculation burden from your core system processor.
Q4: How can we request the full design footprints and memory map programming guides?
A: Please complete our Quick Inquiry contact form. Our application support desk will process your inquiry and dispatch the available technical PDF documents within 24 hours.
