W25N512GVEIR

The W25N512GVEIR is a 3.0V, 512 Mbit serial SLC NAND flash memory device featuring Dual/Quad SPI operation with buffer read and continuous read modes. It provides a 64M × 8 memory organization and a compact 8-WSON (8×6 mm) exposed pad package for space-constrained designs.

Designed for non-volatile storage in embedded systems, the device delivers high-density flash storage with support for Quad I/O, a maximum clock frequency of 166 MHz, and on-die management features suited to firmware, data storage and system code retention where reliable, compact flash is required.

Key Features

• Memory Architecture 512 Mbit SLC NAND flash organized as 64M × 8 for high-density serial non-volatile storage.
• Interface and Modes Serial SPI with Dual and Quad SPI instructions supported; BUF (buffer read) and continuous read modes available per device configuration.
• Performance Up to 166 MHz clock frequency and 6 ns access time for fast read operations; buffer read and continuous read options improve sustained throughput.
• Program/Erase Timing Page/program write cycle time example: 700 µs (word/page), with dedicated program and erase instruction support in the command set.
• Power and Voltage Operates from a 2.7 V to 3.6 V supply range to support common 3V embedded power rails.
• Package and Thermal Supplied in an 8-WSON (8×6 mm) exposed pad package; rated operating temperature range −40°C to 85°C (TA).
• On-Die Management and Protection Includes status/configuration registers, ECC status reporting, bad block management and block protection features as documented in the device instruction set.

Typical Applications

• Firmware and Boot Storage: Non-volatile storage for boot code and firmware images using serial Quad-SPI for fast code fetch.
• Embedded Data Storage: High-density SLC NAND for retention of configuration, logs and application data in embedded systems.
• System Code and Lookup Tables: Storage of large read-only or updateable code/data tables leveraging buffer read and continuous read modes.

Unique Advantages

• High-density SLC NAND: 512 Mbit capacity in a single-chip solution reduces board area compared to multiple lower-density devices.
• Flexible High-speed SPI I/O: Dual/Quad SPI and 166 MHz clock capability enable higher read throughput where supported by the host.
• Compact, Thermal-friendly Package: 8-WSON (8×6 mm) exposed pad package balances small footprint with thermal dissipation for embedded layouts.
• On-chip Management Features: Built-in protection registers, ECC status reporting and bad block management simplify firmware-level flash management and reliability handling.
• Wide Supply Range: 2.7 V to 3.6 V operation supports common 3V system rails for straightforward integration.
