GENERAL DESCRIPTION
The EN25S20 is a 2 Megabit (256K-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 EN25S20 is designed to allow either single
Sector/Block
at a time or full chip erase operation. The
EN25S20 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
or block
.
This Data Sheet may be revised by subsequent versions
or modifications due to changes in technical specifications.
