Description

Introduction and Function & Applications:

The W25N02KW, developed by Winbond, is a 2G-bit SLC QspiNAND Flash Memory that provides a compact storage solution for systems with limited space, pins, and power. Belonging to the W25N family of QspiNAND flash memories, this device incorporates the commonly used SPI interface with the traditional large non-volatile NAND memory space. It offers compatibility with SPI, Dual SPI, and Quad SPI.

The W25N02KW serves multiple functions in various applications, most notably where high capacity and small form factor are essential. It works well for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing voice, text, and data. This versatility of use lends it to be adopted in a range of embedded applications.

Performance Parameters:

The W25N02KW offers impressive performance specifications, supporting SPI clock frequencies up to 104MHz. This enables equivalent clock rates of 208MHz and 416MHz for Dual and Quad I/O respectively when using the Fast Read Dual/Quad I/O commands. The device provides a new Sequential Read Mode designed for efficient access to the entire memory array using a single Read command. Additionally, it offers 50MB/S sequential data transfer rate and Fast Program/Erase performance.

Package Types, Interface & Pin Configuration:

The W25N02KW comes in two space-efficient packages, the 8-pad WSON 8x6-mm, and the 24-ball TFBGA 8x6-mm. Its interface supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI: Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD).

Reliability & Lifespan:

Reliability and longevity are crucial parameters for flash memory. The W25N02KW offers 100,000 erase/program cycles and 10-year data retention. To enhance manageability, it presents user-configurable internal ECC. It operates on a single 1.70V to 1.95V power supply with a -40°C to +85°C/105°C operating range.

Standards & Certifications:

The W25N02KW adheres to the JEDEC standard for manufacturer and device ID. It has one Unique ID page, one parameter page and ten 2,048-Byte OTP pages, ensuring advanced security measures and compliance with regulatory requirements.

Application Cases & Reference Designs:

Designed to simplify life for embedded designers working on NOR flash systems requiring densities beyond 512Mb, the W25N02KW emerges as a cost-effective QspiNAND flash solution. It comes equipped with built-in ECC that helps in detecting and correcting errors, thereby offloading these tasks from the controller.

One crucial application case of W25N02KW is in code shadowing, where the system transfers code stored in flash to DRAM for faster execution. Winbond's continuous read functionality enables quick transfer of NAND contents to the DRAM, which significantly enhances system efficiency.
