Description

MX25U6435FBBI-10G is Macronix’s 64-Mbit serial NOR flash memory. It uses a high-speed SPI family interface with support for SPI, Dual SPI, Quad I/O, and QPI modes for fast reads. The device operates from 2.7–3.6 V and stores 8 MB of data. It features 256-byte pages, 4 KB sectors, and 32/64 KB blocks, with standard page-program, sector/block erase, and chip-erase operations. Optional features include Deep Power-Down/Release and security options. Packaging is an 8-pin device (BBI code). Typical applications are firmware and data storage for microcontrollers and embedded systems, bootloaders, and code updates. For exact timing, endurance, and electrical characteristics, refer to the MX25U6435FBBI-10G datasheet.
