The W25Q64JVSSIQ from Winbond Electronics is a 64Mbit (8MB) serial NOR Flash memory designed for high-performance and low-power applications. It operates with a 3.3V power supply and is housed in a compact 8-pin SOIC package (208mil body width), making it suitable for space-constrained designs.

Key Features

• Memory density: 64Mbit (8,388,608 bytes)
• Interface: Supports standard SPI (CLK, /CS, DI, DO), Dual SPI, and Quad SPI (IO0-IO3) for flexible read/write operations
• Clock frequency: Up to 133 MHz for normal read, with faster throughput in Quad SPI mode (to be verified for exact maximum)
• Supply voltage: 2.7V to 3.6V, compatible with typical 3.3V systems
• Operating temperature range: -40°C to +85°C (industrial grade)
• Page program: 256 bytes per page, sector erase (4KB), block erase (32KB/64KB), and chip erase
• Write protection: Supports hardware and software write protection features
• Endurance: 100,000 program/erase cycles (typical) and 20-year data retention (to be verified)

Applications

• Embedded systems and firmware storage
• IoT devices and smart sensors
• Consumer electronics (e.g., set-top boxes, routers)
• Industrial control and automation
• Automotive electronics (if qualified, check datasheet)

Selection Guidance

The W25Q64JVSSIQ is part of the W25Q series, offering a balance of density, speed, and package options. When selecting, consider the required interface mode (Quad SPI for higher throughput), operating voltage, and temperature range. For applications needing lower voltage (1.8V), refer to the W25Q64JV series variants. Always verify the latest datasheet for exact specifications and part number suffixes (e.g., temperature grade, package type).
