W25Q32JV 32Mbit (4MB) SPI NOR Flash Memory IC — SOP-8, 133MHz, QSPI (5-Pack)
The W25Q32JV is a 32Mbit (4MB) serial NOR flash memory IC from Winbond in a SOP-8 SMD package. Supporting standard SPI, Dual SPI, and Quad SPI (QSPI) at up to 133MHz, it is the most common flash IC used for ESP8266 and ESP32 firmware storage, router and IoT device firmware, and embedded data logging. With 100,000 erase/write cycles and 20-year data retention, it provides reliable non-volatile storage for demanding embedded applications.

Why Choose W25Q32JV?
- ESP8266 / ESP32 native flash — the exact IC used on most ESP8266 and ESP32 modules for firmware storage
- QSPI support — 4× faster than standard SPI for XIP (execute-in-place) code execution
- 133MHz max clock — high-speed data transfer for demanding embedded applications
- 100K erase cycles — long service life for OTA firmware update and data logging
- Winbond W25Q series — most widely supported flash IC in open-source tools (esptool, flashrom, OpenOCD)
Compatible With
- ESP8266 modules: ESP-01, ESP-12E/F — direct replacement for failed or corrupted flash
- ESP32 modules: ESP32-WROOM-32, ESP32-WROVER — external flash expansion or replacement
- STM32: External QSPI flash via QUADSPI peripheral
- Raspberry Pi: SPI flash via spidev / flashrom
- Programmer tools: CH341A, RT809H, T48, XGecu TL866II Plus, esptool.py
- Arduino libraries: SPIMemory, SerialFlash
Frequently Asked Questions
Q: What is the difference between W25Q32JV and W25Q32FV?
A: Both are 32Mbit SOP-8 NOR flash. W25Q32JV is the newer generation with QSPI (Quad Peripheral Interface) support and slightly lower power consumption. W25Q32FV is the older generation without QPI mode. For ESP8266/ESP32 replacement, either works — W25Q32JV is preferred for new designs.
Q: Can I use W25Q32JV to replace the flash on an ESP-01 module?
A: Yes. The ESP-01 uses a W25Q32 (or equivalent) in SOP-8. Desolder the original IC with hot air, clean the pads, and solder the new W25Q32JV. Then flash the firmware using esptool.py: esptool.py --port COM3 write_flash 0x0 firmware.bin
Q: How do I read/write W25Q32JV with a CH341A programmer?
A: Connect the W25Q32JV to the CH341A SOP-8 clip or socket. Open NeoProgrammer or AsProgrammer, select W25Q32JV from the chip list, and use Read/Write/Verify functions. Ensure the chip is powered at 3.3V (use the CH341A’s 3.3V output, not 5V).
