Summary description
The M25P20 is a 2 Mbit (256K x 8) 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 memory is organized as 4 sectors, each containing 256 pages. Each page is 256 bytes
wide. Thus, the whole memory can be viewed as consisting of 1024 pages, or 262,144
bytes.
The whole memory can be erased using the Bulk Erase instruction, or a sector at a time,
using the Sector Erase instruction.
In order to meet environmental requirements, Numonyx offers these devices in ECOPACK®
packages.
ECOPACK® packages are Lead-free and RoHS compliant.
