W25Q64JVSIQ SMD IC SOP8 SOIC8 WINBOND W25Q64JVSIQ

Product Overview:

A high-performance monolithic serial flash memory integrated circuit designed for space-constrained systems requiring low pin counts and high storage density. Utilizing an advanced SPI, Dual-SPI, and Quad-SPI interface architecture, it executes code directly out of flash or transfers large files to working memory at speeds that outperform standard parallel flash memories, making it highly optimized for computing, networking, and high-reliability consumer electronic platforms.

Features

• Expanded Memory Storage Capacity: Houses 64 Megabits (equivalent to 8 Megabytes) of structured digital data storage organized into 32,768 programmable pages.

• High-Speed Multiplexed SPI Communication: Standard SPI operations smoothly scale into Dual-SPI or Quad-SPI modes, leveraging multiple data pins to deliver high throughput equivalent clock rates up to 532 MHz.

• Broad Operating Supply Range: Functions reliably over a standard 3V electronic power rail spanning from 2.7V up to 3.6V.

• Efficient Granular Erase Options: Supports versatile uniform sector erase (4 Kilobytes), block erase (32 or 64 Kilobytes), and full chip erase operations to easily manage memory rewriting.

• Low Operational Power Footprint: Conserves system battery life with an active read current consumption of only 4 mA, which drops down to an ultra-low 1 microampere during deep power-down sleep states.

• Enhanced Security and Identification: Integrates a 64-bit unique factory electronic serial number, a 3-word 256-byte security register array with OTP lockable protection, and a software-assigned individual status register device ID.

• Dedicated Hardware Hold and Reset: Features selectable HOLD or hardware RESET control options on pin 7 to suspend bus communication or initialize the chip state during active system operational faults.

Applications

• Computer Motherboard Firmware: Stores the fundamental input-output system (BIOS) or Unified Extensible Firmware Interface (UEFI) code for laptops, desktops, and industrial servers.

• Networking Communication Hardware: Acts as the primary non-volatile boot and operating system memory inside routers, modems, wireless access points, and network switches.

• Smart Television Panels and Set-Top Boxes: Holds localized operational graphics, user preference logs, and embedded controller execution code.

• Industrial Automation Systems: Stores configuration maps, automated assembly algorithms, and critical calibration records for factory instrumentation.

• High-Speed Hard Drive Controllers: Serves as the temporary microcode cache and execution layer on solid-state drives and hard disk controller boards.
