Overview of W35T51NWTBIE – OCTALFLASH, 512M-BIT, 4KB UNIFOR
The W35T51NWTBIE is a Winbond SpiFlash® octal I/O non-volatile flash memory device with 512 Mbit capacity organized as 64M × 8. It is built on SLC NAND flash technology and provides high-density storage with an Octal SPI interface for high-throughput serial access.
Designed for systems that require compact, high-speed persistent memory, this device targets embedded applications that benefit from a 200 MHz clock, 5 ns access time, and a 1.65 V–2.0 V supply range while operating across a -40 °C to 85 °C temperature window.
Key Features
- Memory Architecture 512 Mbit capacity organized as 64M × 8 using FLASH - NAND (SLC) technology for non-volatile code and data storage.
- Interface & Performance SPI Octal I/O interface with a maximum clock frequency of 200 MHz and a specified access time of 5 ns to support high-speed serial transfers.
- Write Performance Page/program write cycle time specified at 1.5 ms for word/page programming operations.
- Voltage & Power Operates from 1.65 V to 2.0 V, enabling integration into low-voltage system domains.
- Temperature Range Industrial temperature support from -40 °C to 85 °C (TA) for deployment in a wide range of environments.
- Package Supplied in a 24-pin TFBGA package (24-TFBGA, 8×6) / 24-TBGA package format suitable for compact board designs.
Typical Applications
- Embedded Systems High-density non-volatile storage for firmware, boot images, and large data blocks in embedded controllers and modules.
- Consumer Electronics Persistent code and content storage where compact package and low-voltage operation are required.
- Industrial Equipment Firmware and configuration storage that must operate across an industrial temperature range (-40 °C to 85 °C).
Unique Advantages
- High-density 512 Mbit capacity: Provides large non-volatile storage in a single 64M × 8 device, reducing board-level component count.
- Octal SPI interface at 200 MHz: Enables higher throughput serial access compared to standard SPI modes for faster system boot and data transfer.
- SLC NAND flash technology: Delivers the non-volatile storage characteristics of single-level cell NAND within the specified memory organization.
- Low-voltage operation: 1.65 V to 2.0 V supply range facilitates integration into modern low-voltage power domains.
- Industrial temperature rating: -40 °C to 85 °C operation supports a broad range of deployment environments.
- Compact BGA package: 24-TFBGA (8×6) format minimizes PCB footprint for space-constrained designs.
