GENERAL DESCRIPTION
The EN25B32 is a 32M-bit (4096K-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 EN25B32 has sixty eight sectors including sixty three 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 EN25B32 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 1
or modifications due to changes in technical specifications.
