W25N512GWEIT

The W25N512GWEIT is a non-volatile 512 Mbit serial SLC NAND flash memory device with support for Standard, Dual and Quad SPI interfaces. It implements buffer read and continuous read modes and provides a SPI‑Quad I/O memory interface for high‑throughput serial access.

Designed for systems requiring 1.7V–1.95V power and industrial temperature range (-40°C to 85°C), the device serves as code or data storage in embedded and connected applications where compact high‑density flash and flexible SPI modes are required.

Key Features

• Memory Type & Organization 512 Mbit SLC NAND flash organized as 64M x 8, delivering non‑volatile storage in a serial flash form factor.
• Serial Interface SPI interface with Standard, Dual and Quad SPI instructions and Quad I/O support for higher serial throughput.
• Read Modes Buffer Read and Continuous Read modes are supported to optimize sequential data transfers and streaming.
• Performance 104 MHz maximum clock frequency and 7 ns access time for fast serial read operations.
• Program / Erase Supports standard program and erase commands including 128 KB block erase and quad load program instructions (quad/random load program opcodes included in instruction set).
• Power Low‑voltage operation across a 1.7V to 1.95V supply range.
• Data Protection & Configuration Multiple protection and configuration registers including volatile/OTP‑lockable bits, write protect and status registers; ECC enable bit and other status indicators are available.
• Write Timing Typical write cycle time for a word/page listed as 700 µs.
• Package & Temperature Available in an 8‑WDFN exposed pad package (8‑WSON, 8×6 mm) and rated for operation from -40°C to 85°C (TA).

Typical Applications

• Embedded Firmware Storage Compact 512 Mbit SLC NAND storage for system firmware and boot code in low‑voltage embedded platforms.
• Consumer & IoT Devices Serial Quad I/O and buffer/continuous read modes support fast code/data retrieval for connected consumer and IoT products operating within the specified supply and temperature ranges.
