W25N512GWFIT

The W25N512GWFIT is a 512 Mbit serial SLC NAND flash memory device from Winbond Electronics' SpiFlash® series. It implements dual/quad SPI I/O with buffer read and continuous read modes for serial non-volatile storage.

Designed for systems requiring compact, low-voltage serial flash storage, the device provides a 64M x 8 memory organization, 1.7 V–1.95 V supply operation, and a 16-SOIC (300 mil) package suitable for space-constrained designs operating from -40°C to 85°C.

Key Features

• Memory Type & Technology Non-volatile FLASH NAND (SLC) memory organized as 64M x 8 delivering 512 Mbit of storage.
• Serial Interface SPI with Dual/Quad I/O support for serial data transfer modes; includes buffer read and continuous read capabilities as detailed in the device instruction set.
• Performance Up to 104 MHz clock frequency and 7 ns access time for serial read operations (as specified).
• Program/Erase Characteristics Supports page and block program/erase operations with a write cycle time (word/page) of 700 µs.
• Voltage and Temperature Low-voltage operation from 1.7 V to 1.95 V and an operating temperature range of -40°C to 85°C (TA).
• Reliability & Control On-chip protection, configuration and status registers (including write protection and OTP lockable bits) plus ECC/status reporting described in the device documentation.
• Package Available in a 16-SOIC (0.295", 7.50 mm width) package for through-hole or wave-solder-compatible PCB designs.

Typical Applications

• Embedded Storage — Non-volatile 512 Mbit SLC NAND for code and data storage in embedded systems requiring serial flash.
• Firmware and Configuration Memory — Stores firmware, lookup tables and configuration data accessible via SPI/Dual/Quad I/O modes.
• Consumer & Industrial Electronics — Compact serial flash option for devices operating within the specified temperature and voltage ranges.

Unique Advantages

• Quad SPI Throughput: Dual/Quad SPI I/O and continuous/buffer read modes enable higher serial data transfer rates within the specified 104 MHz clock limit.
• Low-Voltage Operation: 1.7 V–1.95 V supply supports designs targeting reduced power domains.
• SLC NAND Technology: Single-level cell NAND provides the flash memory architecture used in this device.
• On-Chip Protection & Status: Multiple protection, configuration and status registers (including OTP-lockable bits and ECC status) enable controlled memory management and error reporting.
• Compact SOIC Package: 16-SOIC (300 mil) package simplifies PCB layout in space-constrained applications.
