GENERAL DESCRIPTION

The EN25D16 is a 16M-bit (2048K-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 EN25D16 is designed to allow either single Sector at a time or full chip erase operation. The EN25D16 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.
