M25PXX

SUMMARY DESCRIPTION

The M25Pxx is a 512Kbit to 32Mbit (2M x 8) SerialFlash Memory, with advanced write protectionmechanisms, accessed by a high speed SPI-com-patible bus.

The memory can be programmed 1 to 256 bytes ata time, using the Page Program instruction.

The memory is organized as a number of sectors,each containing 256 or 128 pages. Each page is256 bytes wide.

The whole memory can be erased using the BulkErase instruction, or a sector at a time, using theSector Erase instruction.Figure 2. Logic DiagramVCCFigure 3. SO8 and VDFPN ConnectionsM25PxxSQWVSS12348765AI10259VCCHOLDCDDCSWHOLDM25PxxQNote:1.There is an exposed die paddle on the underside of the

MLP8 package. This is pulled, internally, to VSS, andmust not be allowed to be connected to any other voltageor signal line on the PCB.
