Description
M25P80
The M25P80 is an 8 Mbit (1 Mbit × 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 16 sectors, each containing 256 pages. Each page is 256
bytes wide. Thus, the whole memory can be viewed as consisting of 4096 pages, or
1,048,576 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 the M25P80 in ECOPACK®
packages. ECOPACK® packages are Lead-free and RoHS compliant.
