The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction. The EN25B40 has twelve sectors including seven 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 EN25B40 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.
