M25PXX
SUMMARY DESCRIPTION
The M25Pxx is a 512Kbit to 32Mbit (2M x 8) Serial
Flash Memory, with advanced write protection
mechanisms, accessed by a high speed SPI-com-
patible 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.

Note: 1. There is an exposed die paddle on the underside of the
MLP8 package. This is pulled, internally, to VSS, and
must not be allowed to be connected to any other voltage
or signal line on the PCB.
