W25N512GVEIT

The W25N512GVEIT is a 512 Mbit serial SLC NAND flash memory device implementing Dual/Quad SPI I/O and designed for non-volatile data storage. It integrates buffer read and continuous read modes and provides a serial interface optimized for high-throughput read operations.

This device targets systems that require compact, high-density non-volatile memory with industry-standard SPI/Quad I/O connectivity and configurable protection and status features for robust data management.

Key Features

• Memory Type & Capacity  512 Mbit SLC NAND flash organized as 64M × 8 for byte-oriented access and efficient storage management.
• Serial Interface  Supports SPI with Dual and Quad I/O modes, enabling wider data paths for accelerated read throughput.
• Read Modes  Buffer Read and Continuous Read modes are supported to optimize sequential read performance and reduce host overhead.
• Performance  Up to 166 MHz clock frequency and a 7 ns access time specification for responsive data access in serial operations.
• Program/Erase Timing  Page program write cycle time specified at 700 µs for predictable write timing.
• Supply Voltage  Operates across a 2.7 V to 3.6 V supply range to match common 3.3 V system rails.
• Package  Available in an 8-WDFN exposed pad variant and listed supplier device package 8-WSON (8×6) for compact PCB mounting.
• Temperature Range  Rated for operation from –40 °C to 85 °C (TA) for industrial-temperature applications.
• Protection & Management  On-chip protection and configuration registers, status registers, ECC enable/monitoring bits, and bad-block management features as documented in the device instruction set and status register descriptions.

Unique Advantages

• High-density serial storage: 512 Mbit capacity in a compact serial-NAND form factor provides substantial non-volatile storage while minimizing PCB area.
• Flexible high-speed I/O: Dual/Quad SPI modes and up to 166 MHz clock support allow designers to scale read bandwidth without changing the fundamental SPI-based interface.
• Optimized sequential reads: Buffer Read and Continuous Read modes reduce host transaction overhead for large or streaming data reads.
• Predictable write timing: Specified write cycle time (700 µs) gives deterministic program timing for system-level scheduling.
• Robust data management: Built-in status, protection registers, ECC enable bits and bad-block management enable controlled protection and monitoring of stored data as described in the device documentation.
• Wide operating conditions: Operation from 2.7 V to 3.6 V and –40 °C to 85 °C supports deployment across common industrial environments and 3.3 V system designs.
