MX25U8035FM1I

MX25U8035FM1I is Macronix’s MX25U-series 8‑Mbit serial NOR flash memory. It stores firmware/data for embedded systems and is SPI‑interface driven, supporting standard SPI, dual SPI, and Quad I/O (DQ pins) modes (and can operate in QPI for faster reads). The device is organized as 1,048,576 bytes with a 256‑byte page; erase granularity includes 4K sectors and 32K/64K blocks. It supports page programming, fast Read, and typical protection features (write enable/disable, status and block protection). Endurance is typically around 100k program/erase cycles with long data retention. The part is available in an 8‑pin package (SOP/USON) with commercial and industrial temperature grades. Common uses include boot firmware storage and code/data storage in microcontrollers and other embedded systems requiring low pin count and reliable random access.

Equivalent 8 Mbit SPI serial flash devices from other vendors include: Winbond W25Q80BV / W25Q80DV; GigaDevice GD25Q80B; ISSI IS25LP080D; Spansion/Cypress S25FL080P; Puya P25Q80; Macronix MX25L8035F. Always verify voltage (3.0–3.6V), speed grade, and opcodes for full compatibility.
