W74M64FVSSIQ TR

The W74M64FVSSIQ TR is a 64 Mbit non-volatile NAND flash memory from Winbond Electronics' SpiFlash® series. It provides an 8M × 8 memory organization with a SPI – Quad I/O interface for serial flash storage.

Designed for embedded designs requiring compact, serial non-volatile storage, the device operates over a 2.7 V to 3.6 V supply and supports an 80 MHz clock frequency, making it suitable for applications that need moderate-density external flash in a small package.

Key Features

• Memory Type & Capacity 64 Mbit NAND flash memory organized as 8M × 8 for non-volatile data and code storage.
• Interface SPI – Quad I/O interface provides serial access to the flash array for typical SPI or quad I/O transactions.
• Performance 80 MHz clock frequency for serial bus operations as specified.
• Voltage Wide supply range from 2.7 V to 3.6 V to support common 3 V system rails.
• Operating Temperature Specified for −40°C to 85°C (TA), accommodating a wide range of ambient conditions.
• Package Standard 8-SOIC (0.209", 5.30 mm width) surface-mount package for space-efficient board designs.

Typical Applications

• Firmware and Boot Storage Non-volatile NAND flash for storing firmware images and boot code in embedded products.
• Embedded Systems External program or data storage for microcontroller- or CPU-based systems using SPI or Quad I/O.
• Consumer Electronics Serial flash memory for firmware, settings, or content storage in compact consumer devices.
• Industrial Devices On-board non-volatile storage for devices operating within the −40°C to 85°C temperature range.

Unique Advantages

• Moderate Density (64 Mbit): Provides a balance of capacity and board footprint for applications that need more than small serial EEPROM sizes.
• Quad I/O Support: SPI – Quad I/O interface enables higher parallelism on the serial bus compared to single-bit SPI transfers.
• 80 MHz Clock Capability: Supports serial bus operation at up to the specified 80 MHz clock frequency for efficient data transfers.
• Flexible Supply Range: Operates across 2.7 V to 3.6 V, matching common system power rails without additional level shifting.
• Compact 8-SOIC Package: Standard 8-SOIC footprint simplifies PCB layout and assembly for space-conscious designs.
• Wide Ambient Temperature Range: Rated from −40°C to 85°C, suitable for a variety of environmental conditions.
