GENERAL DESCRIPTION

The EN25F40 is a 4M-bit (512K-byte) Serial Flash memory, with advanced write protection mechanisms,

accessed by a high speed SPI-compatible bus. The memory can be programmed 1 to 256 bytes at a

time, using the Page Program instruction.

The EN25F40 is designed to allow either single Sector/Block at a time or full chip erase operation. The

EN25F40 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.
