1. Description

The FM25F02A is a 2M-bit (256K-byte) Serial Flash

memory, with advanced write protection mechanisms.

The FM25F02A supports the standard Serial

Peripheral Interface (SPI), and a high performance

Dual output as well as Dual I/O.

The FM25F02A 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 FM25F02A

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.
