SUMMARY DESCRIPTION
Figure 3. SO8 and VDFPN Connections
The M25Pxx is a 512Kbit to 32Mbit (2M 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 a number of sectors,
each containing 256 or 128 pages. Each page is
256 bytes wide.
The whole memory can be erased using the Bulk
Erase instruction, or a sector at a time, using the
Sector Erase instruction.
