MX25L3206EM2I-12G 32Mbit SPI NOR Flash Memory IC – SOP-8, Pack of 5

The MX25L3206EM2I-12G (MX25L3206E) from Macronix is a 32Mbit (4MB) SPI NOR flash memory IC in a standard SOP-8 package – a widely used alternative to the Winbond W25Q32 in BIOS chips, router firmware, and embedded systems. With 86MHz SPI clock support, Dual SPI capability, and the same standard SOP-8 pinout as the W25Q32 and GD25Q32, it's pin-compatible and command-compatible with the most popular 32Mbit flash ICs on the market. This 5-piece pack is ideal for BIOS replacement, firmware recovery, and embedded storage design.

MX25L3206E vs W25Q32JV – Comparison

MX25L3206E: 86MHz max, Dual SPI only (no Quad SPI), Macronix – widely used in older BIOS and routers
W25Q32JV: 133MHz max, Quad SPI (QSPI) support, Winbond – current generation with higher throughput
Both are pin-compatible (same SOP-8 pinout) and command-compatible for standard SPI operations
Choose MX25L3206E as a direct replacement for existing MX25L3206 in BIOS and router repair

Typical Applications

BIOS / UEFI replacement: Motherboard and laptop BIOS chip replacement (common in older systems)
Router firmware: Firmware storage in routers using MX25L3206 (very common)
Embedded systems: Firmware and data storage for microcontrollers
IoT devices: Configuration and firmware storage
Data logging: Non-volatile storage for sensor data

Compatible / Interchangeable Parts

Pin-compatible and SPI-compatible with: W25Q32JV (Winbond), GD25Q32 (GigaDevice), S25FL032P (Spansion), EN25Q32B (EON). All share the same SOP-8 pinout and standard SPI command set for read, write, and erase operations.
