The EN25F16 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 EN25F16 is designed to allow either single Sector at a time or full chip erase
operation. The EN25F16 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.
