Description The FM25Q04B is a 4M-bit (512K-byte) Serial Flash memory, with advanced write protection mechanisms. The FM25Q04B supports the standard Serial Peripheral Interface (SPI), Dual/Quad I/O as well as 2-clock instruction cycle Quad Peripheral Interface(QPI). They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The FM25Q04B can be programmed 1 to 256 bytes at a time, using the Page Program instruction. It is designed to allow either single Sector/Block at a time or full chip erase operation. The FM25Q04B can be configured to protect part of the memory as the software protected mode. The device can sustain a minimum of 100K program/erase cycles on each sector or block.  High Reliability – Endurance: 100,000 program/erase cycles – Data retention: 20 years  Green Package – 8-pin SOP (150mil) – 8-pin USON (0.55mm) – All Packages are RoHS Compliant and Halogenfree 3.
