W25N512GWEIT

Introduction:

Winbond has developed the W25N512GW, a 512M-bit Serial SLC NAND Flash memory under the category QspiNAND Flash. This innovative memory solution is designed for systems with limited space, pins, and power requirements, incorporating the popular SPI interface and the traditional large NAND non-volatile memory space. The W25N512GW is suitable for numerous applications, including code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing voice, text, and data.

Function & Applications:

The W25N512GW offers a versatile memory solution with a single 1.70V to 1.95V power supply, featuring low power consumption (as low as 25mA active, 10µA standby, and 1¬µA deep power down) and a wide temperature range (-40°C to +85/105°C). The memory is organized into 32,768 programmable pages, each containing 2048 bytes. It supports Standard SPI, Dual/Quad I/O SPI, and is compatible with SPI serial flash commands.

Performance Parameters:

This high-performance Serial NAND Flash operates at 104MHz Standard/Dual/Quad SPI clocks, with equivalent clock rates of 208/416MHz for Dual/Quad SPI. It offers a continuous data transfer rate of 50MB/s, fast program/erase performance, 100,000 erase/program cycles, and a 10-year data retention.

Package Types, Interface & Pin Configuration:

The W25N512GW is available in space-saving packages, including 8-pad WSON 6x5-mm, 8-pad WSON 8x6-mm, 16-pin SOIC 300-mil, 24-ball TFBGA 8x6-mm, and 48-ball WLCSP. The device supports the standard Serial Peripheral Interface (SPI) with Chip Select, Serial Data, Write Protect, and Hold pins.

Reliability & Lifespan:

With its built-in ECC (Error Correcting Code) and bad block management, the W25N512GW guarantees reliability and manageability, even under harsh conditions and continuous use. The device supports on-chip 1-Bit ECC for the memory array and ECC status bits, indicating ECC results.

Standards & Certifications:

The W25N512GW conforms to JEDEC standard manufacturer and device ID, Unique ID page, Parameter page, and ten 2,048-Byte OTP pages. It also offers software and hardware write protection, power supply lock-down, and OTP protection.

Application Cases & Reference Designs:

Winbond's QspiNAND Flash memory is widely used in embedded systems requiring high-speed data transfer and code shadowing, such as IoT devices, automotive computers, and industrial control systems. With its continuous read functionality and on-chip ECC, this memory solution enables direct, efficient access to the entire memory array, making it ideal for code shadowing applications and improving overall system performance.
