M25P32

SUMMARY DESCRIPTION

The M25P32 is a 32Mbit (4M 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 256 bytes at

a time, using the Page Program instruction.

The memory is organized as 64 sectors, each con-

taining 256 pages. Each page is 256 bytes wide.

Thus, the whole memory can be viewed as con-

sisting of 16384 pages, or 4,194,304 bytes.

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.

2. See PACKAGE MECHANICAL section for package di-

mensions, and how to identify pin-1.
