W25Q128JVSJQ – Serial NOR Flash – Winbond

About this part

The Winbond W25Q128JVSJQ is a 128M-bit (16M-byte) Serial NOR Flash memory from the high-performance W25Q128JV SpiFlash family. It delivers a compact, low-power code-storage and data-storage solution for embedded systems with limited space, pins, and power. The device supports the standard Serial Peripheral Interface (SPI) plus Dual and Quad I/O SPI, enabling fast code shadowing to RAM, execute-in-place (XIP) operation directly from Dual/Quad SPI, and storage of voice, text, and data.

This specific orderable variant, W25Q128JVSJQ, decodes per the Winbond ordering guide as: S = 8-pin SOIC 208-mil package, J = Industrial Plus temperature grade (-40°C to +105°C), and Q = Green package (lead-free, RoHS compliant, halogen-free, antimony-oxide-free) with the Quad Enable (QE) bit fixed to 1 in Status Register-2, backward compatible to the FV family.

Key Features

• Density: 128M-bit (16M-byte) Serial NOR Flash
• Memory organization: 65,536 programmable pages of 256 bytes each; 4,096 erasable 4KB sectors; 256 erasable 64KB blocks
• Interface: Standard SPI plus Dual and Quad I/O SPI (CLK, /CS, DI, DO, IO2, IO3)
• Clock frequency up to 133MHz; equivalent 266MHz (Dual I/O) and 532MHz (Quad I/O) for Fast Read
• Erase granularity: 4KB sector, 32KB block, 64KB block, and full chip erase
• Single 2.7V to 3.6V power supply; power-down current as low as 1µA
• Package: 8-pin SOIC, 208-mil body width
• Temperature grade: Industrial Plus, -40°C to +105°C
• JEDEC-standard manufacturer/device ID and SFDP support
• 64-bit unique serial number and three 256-byte Security Registers
• Green package: lead-free, RoHS compliant, halogen-free; QE = 1 (fixed)

Applications

• Microcontroller and SoC boot/code storage (XIP)
• Firmware and code shadowing to RAM
• IoT and connected-device data and parameter storage
• Networking, industrial control, and automotive-adjacent embedded systems
• Consumer electronics, set-top boxes, and display modules

Why Source W25Q128JVSJQ from Pacific Component Xchange

Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete memory. The W25Q128JVSJQ Industrial Plus variant frequently sees little to no authorized-distributor availability, making secondary-market sourcing essential for production continuity. Our team supports buyers who need verified, authentic devices with global shipping and responsive quotes.
