The MX25R8035FM1IH1/TUBE is a low-power 8Mbit SPI Serial Flash memory module manufactured by Macronix. It features backward programming compatibility, sector protection, high performance instruction set, dual/quad SPI operation, and programmable clock speed. This module also has a fast access time, small footprint, and an extended temperature operation range of -40 to +85 Celsius. Its dual/quad SPI operation allows for data transfer speeds of up to 104MHz. Additionally, it has a unique write protection feature, allowing it to be disabled during non-volatile operation. Beyond that, the module has a deep power-down mode, meaning it can remain powered down until an external write or read command is issued.
