W25Q64JV 64Mbit (8MB) SPI NOR Flash Memory IC — SOP-8, 133MHz, QSPI (5-Pack)
The W25Q64JVSSIQ / W25Q64JVSIQ is a 64Mbit (8MB) serial NOR flash memory IC from Winbond in a SOP-8 SMD package. Operating at up to 133MHz with standard SPI, Dual SPI, and Quad SPI (QSPI) interfaces, it is the industry-standard flash chip used in BIOS/UEFI firmware storage, router firmware, ESP32/ESP8266 program storage, and embedded data logging applications.

Frequently Asked Questions
Q: What is the difference between W25Q64JVSSIQ and W25Q64JVSIQ?
A: Both are 64Mbit SOP-8 NOR flash. The W25Q64JVSSIQ supports standard/dual/quad SPI; the W25Q64JVSIQ additionally supports QPI (Quad Peripheral Interface) mode for even faster quad I/O. For most BIOS replacement and ESP32 use, either variant works identically.
Q: Can I use this to replace a BIOS chip on my laptop motherboard?
A: Yes, if the original chip is a W25Q64 variant in SOP-8. Read the original chip first with a CH341A programmer to back up the firmware, then write to the new chip. Verify the exact part number and voltage (2.7–3.6V) matches your board.
Q: Is this compatible with the Arduino SPI Flash library?
A: Yes. The W25Q64JV is supported by the SPIMemory and SerialFlash Arduino libraries. Use the standard SPI pins (MOSI, MISO, SCK, CS) and initialize with the correct chip size (8MB / 64Mbit).
