W25N512GWBIR TR

The W25N512GWBIR TR is a 1.8V, 512‑Mbit serial SLC NAND flash memory device from Winbond's SpiFlash® family. It implements Dual/Quad SPI with buffer read and continuous read modes and is organized as 64M × 8 for non‑volatile data storage.

Designed for space‑constrained embedded systems, the device delivers quad I/O serial access, on‑die management features and a compact 24‑TFBGA (6×8) package for low‑voltage 1.8V applications operating from −40°C to 85°C.

Key Features

• Memory Architecture  SLC NAND flash technology, 512 Mbit capacity organized as 64M × 8 for byte‑wide serial access.
• Serial Interface  SPI interface with Quad I/O support and Dual/Quad SPI instruction sets for higher throughput.
• Read Modes  Buffer read and continuous read modes to support efficient sequential data retrieval.
• Performance  Clock frequency up to 104 MHz with an access time of 7 ns and a write cycle time (word/page) of 700 µs.
• Power  Low‑voltage operation with a supply range of 1.7 V to 1.95 V (nominal 1.8 V).
• Package  24‑TFBGA package (6×8) in a compact surface‑mount form factor.
• Temperature Range  Operating ambient temperature from −40°C to 85°C (TA).
• On‑die Management  Built‑in protection and configuration registers, bad block management instructions and ECC status reporting to support memory management and error visibility.

Typical Applications

• Embedded storage for 1.8V systems  Provides non‑volatile program and data storage where 1.8V supply operation and a small package are required.
• Firmware and code memory  Serial SLC NAND in a Quad SPI interface supports storage and execution of firmware images in resource‑constrained designs.
• Sequential data logging  Buffer and continuous read modes enable efficient retrieval of stored data in embedded logging or measurement systems.

Unique Advantages

• High‑density in a compact package: 512 Mbit capacity in a 24‑TFBGA (6×8) package reduces board area while providing ample non‑volatile storage.
• Flexible, high‑speed SPI interface: Dual/Quad SPI and a 104 MHz clock option enable faster serial transfers compared with single‑I/O SPI implementations.
• Low‑voltage operation: 1.7 V to 1.95 V supply range supports 1.8V platform compatibility and lower system power rails.
• On‑die management and visibility: Protection/configuration registers, bad block management and ECC status bits assist in managing memory health and reliability.
• Efficient sequential access: Buffer read and continuous read modes improve throughput for streaming and sequential read patterns.
• Wide operating temperature: −40°C to 85°C support for a broad range of ambient environments.
