Overview

The Winbond W25N04KWZEIR is a 4Gbit (512MByte) Serial NAND Flash memory IC. It offers a high-speed SPI interface with support for Dual and Quad I/O modes, operating up to 104 MHz. This SLC NAND flash integrates an on-chip 8-bit ECC for data integrity and is suitable for applications requiring non-volatile storage in a compact WSON-8 package.

Why Choose This Part

This Serial NAND Flash provides a significant storage capacity of 4Gbit, accessible via a high-speed SPI interface supporting Dual and Quad I/O for faster data transfer. The integrated 8-bit ECC helps ensure data reliability, which is crucial for NAND flash. Its compact 8x6mm WSON-8 package and wide operating voltage range from 1.7V to 1.95V are beneficial for space-constrained and low-power designs.

Applications

Embedded System Code Storage
