SUMMA RY DESCR IPTIO N

The M25P xx is a 512Kbit to 32Mbit (2M x 8) Serial

Flash Memory, with advanced write protection

mechanisms , accessed by a hi gh speed SPI-com-

patible bus.

The memory can be programmed 1 to 256 byt es at

a time, using the Page Progr am instruction.

The mem ory is organized as a number of sectors,

each containing 256 or 128 pages. Each page is

256 bytes wide.

The whole mem ory can b e erased usi ng the Bulk

Erase instruction, or a sector at a time, using the

Sector Erase instruction.

Note : 1. There is an expose d 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 si gnal line on the PCB.
