M25P40
SUMMARY DESCRIPTION
The M25P40 is a 4 Mbit (512K 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 8 sectors, each con-
taining 256 pages. Each page is 256 bytes wide.
Thus, the whole memory can be viewed as con-
sisting of 2048 pages, or 524,288 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 V
SS
, and
must not be allowed to be connected to any other voltage
or signal line on the PCB.

section for package di-
mensions, and how to identify pin-1.
