FM25Q08B 8M-BIT SERIAL FLASH MEMORY
Preliminary
Datasheet

1. Description
The FM25Q08B is a 8M-bit (1M-byte) Serial Flash
memory, with advanced write protection mechanisms.
The FM25Q08B supports the standard Serial
Peripheral Interface (SPI), Dual/Quad I/O as well as 2clock 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 FM25Q08B 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 FM25Q08B
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.
