W25N512GVBIT TR

The W25N512GVBIT TR is a 3.0V, 512 M-bit serial SLC NAND flash memory device from Winbond Electronics featuring Dual/Quad SPI operation. It implements buffer read and continuous read modes and a 64M × 8 memory organization to deliver high-density non-volatile storage in a compact BGA package.

Designed for systems that require serial SLC NAND storage with high-speed SPI I/O, the device combines a 166 MHz clock capability, Quad I/O interface, and a small 24-TFBGA (6×8) footprint with an extended operating temperature range of −40°C to 85°C.

Key Features

• Memory Technology Serial SLC NAND flash memory, 512 Mbit capacity organized as 64M × 8 for high-density non-volatile storage.
• Serial Interface Supports Standard, Dual and Quad SPI instructions and Quad I/O memory interface for accelerated data transfer.
• High-Speed Read Modes Buffer Read and Continuous Read modes are supported to optimize throughput; device clock frequency specified up to 166 MHz.
• Performance Metrics Access time noted at 6 ns and typical write/program cycle time for a word/page of 700 µs.
• Voltage and Temperature Single-supply operation from 2.7 V to 3.6 V with an operating ambient temperature range of −40°C to 85°C (TA).
• Protection and Management On-device protection and configuration registers, status registers including ECC status and bad block management features as documented in the instruction set.
• Package Compact 24-TFBGA (6×8 mm, 5×5 ball array) package case for space-constrained designs.

Typical Applications

• Firmware and Code Storage Non-volatile storage for firmware images and code, leveraging Quad SPI reads and buffer/continuous read modes to accelerate code fetch.
• Embedded Data Logging High-density SLC NAND capacity supports system data logging and local non-volatile storage in embedded devices.
• Consumer and Portable Electronics Compact 24-TFBGA footprint and single 2.7–3.6 V supply make the device suitable for space- and power-constrained consumer modules.
• Industrial Embedded Systems Extended operating temperature range (−40°C to 85°C) supports deployment in industrial environments requiring reliable non-volatile memory.

Unique Advantages

• High-capacity SLC NAND: 512 Mbit SLC NAND provides a balance of density and NAND-type characteristics in a single-chip solution.
• High-speed Quad SPI access: Quad I/O support and up to 166 MHz clock capability enable faster serial data transfers compared with single-bit SPI modes.
• Optimized read modes: Buffer read and continuous read modes reduce latency and improve sustained throughput for sequential access patterns.
• Robust on-chip management: Built-in protection/configuration and status registers, ECC status reporting and bad block management commands simplify integration and reliability monitoring.
• Compact BGA package: 24-TFBGA (6×8) package minimizes board area while providing the required I/O density for Quad SPI operation.
• Wide supply and temperature window: 2.7 V–3.6 V supply range and −40°C to 85°C operating temperature support diverse system power and thermal requirements.
