M25P05
SUMMARY DESCRIPTION
The M25P05 is a 512 Kbit (64K x 8) Serial Flash
Memory, with advanced write protection mecha-
nisms, accessed by a high speed SPI-compatible
bus.
The memory can be programmed 1 to 128 bytes at
a time, using the Page Program instruction.
The memory is organized as 2 sectors, each con-
taining 256 pages. Each page is 128 bytes wide.
Thus, the whole memory can be viewed as con-
sisting of 512 pages, or 65536 bytes.
The whole memory can be erased using the Bulk
Erase instruction, or a sector at a time, using the
Sector Erase instruction.
