W25Q64JVSSIQ Parameter Description

The W25Q64JVSSIQ is a high-density, low-power 64-Megabit (8-Megabyte) Serial NOR Flash memory engineered by Winbond Electronics. It provides an ideal storage extension for space-constrained, battery-operated embedded systems, offering a flexible Standard, Dual, or Quad SPI interface. Clocked at a high-speed 133 MHz, this memory chip delivers an equivalent transfer rate of 532 MHz in Quad SPI mode, meeting the execution-in-place (XIP) performance requirements of modern microcontrollers. Operating over an industrial temperature range (-40°C to 85°C) with a standard 3V supply, it is housed in an industry-proven 8-pin SOIC (208-mil) package, ensuring high reliability for complex firmware layouts.


Technical Highlights & Architectural Merits

Double the Density Portfolio: Offers a spacious 64M-bit (8MB) capacity, providing double the storage footprint of the W25Q32JV for expanded firmware features, localized graphics, or extended data logging.


High-Speed Quad SPI Operations: Supports clock rates up to 133 MHz, delivering up to 50MB/s continuous data transfer rate in Quad I/O mode for rapid boot sequences and responsive firmware execution.


Granular Memory Management: Features a uniform 4KB sector erase alongside 32KB/64KB block erase options, giving engineers flexibility for granular parameter updates and efficient code mapping.


Hardware & Software Protection: Equipped with advanced block write-protection, status register security, and three 256-byte Security Registers with OTP (One-Time Programmable) locks for boot code safety.


Typical Applications

Advanced IoT Gateways: Storing complex networking protocols, Linux-based micro-kernels, and cryptographic keys for smart industrial hubs.


Automotive Infotainment & Telematics: Display frame buffers, instrument cluster graphics storage, and real-time sensor logging modules.


High-End Computing Peripherals: Hard drive controllers, optical network terminals (ONTs), complex printer systems, and mainboard BIOS storage.
