GENERAL DESCRIPTION
The EN25B16 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 EN25B16 has thirty six sectors including thirty one sectors of 64KB, one sector of 32KB, one sector
of 16KB, one sector of 8KB and two sectors of 4KB. This device is designed to allow either single Sector
at a time or full chip erase operation. The EN25B16 can protect boot code stored in the small sectors for
either bottom or top boot configurations. The device can sustain a minimum of 100K program/erase cycles
on each sector.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
