W74M64JVSSIQ

The W74M64JVSSIQ from Winbond Electronics is a 64 Mbit non-volatile NAND FLASH memory device in an 8-SOIC package. It implements an SPI Quad I/O interface and is organized as 8M × 8 to provide byte-oriented FLASH storage for embedded designs.

Designed for systems requiring serial FLASH storage, the device operates over a 2.7 V to 3.6 V supply range, supports clock rates up to 104 MHz, and is specified for an ambient temperature range of −40°C to 85°C.

Key Features

• Memory Capacity and Organization  64 Mbit density organized as 8M × 8 for byte-oriented FLASH storage.
• Technology  NAND FLASH non-volatile memory format suitable for persistent code and data storage.
• Interface and Performance  SPI – Quad I/O memory interface with a maximum clock frequency of 104 MHz to support high-throughput serial transfers.
• Voltage Supply  Operates from 2.7 V to 3.6 V, enabling use with common 3 V system rails.
• Operating Temperature  Specified for −40°C to 85°C (TA) to accommodate a wide range of ambient conditions.
• Package  8-SOIC package (0.209", 5.30 mm width) in a standard supplier device package for through-hole or wave-solder compatible PCB layouts.

Typical Applications

• Embedded code storage  Non-volatile FLASH for storing firmware and application code where a serial SPI/Quad I/O interface and 64 Mbit density are required.
• Boot and configuration data  Persistent storage of bootloaders, configuration tables, or calibration data compatible with 2.7 V–3.6 V systems.
• General-purpose serial data storage  Byte-oriented FLASH storage for logging, parameter storage, or other serial memory needs in systems operating between −40°C and 85°C.

Unique Advantages

• Compact industry-standard package: 8-SOIC footprint (5.30 mm width) simplifies board-level integration and accommodates space-constrained designs.
• Quad I/O SPI interface: Enables higher serial throughput using the device’s Quad I/O capability at clock rates up to 104 MHz.
• Wide supply range: 2.7 V to 3.6 V operation supports common 3 V system rails without additional power conversion.
• Extended ambient temperature: −40°C to 85°C rating supports deployment in a wide range of environmental conditions.
• Byte-oriented organization: 8M × 8 memory organization provides straightforward byte access for firmware and data storage.
