75MHz, Serial Peripheral Interface Flash Memory

Functional Description

The M45PE10 is a 1Mb (128Kb x 8) serial Flash memory device accessed by a high-

speed, SPI-compatible bus.

The memory can be written or programmed 1 to 256 bytes at a time using the PAGE

WRITE or PAGE PROGRAM command. The PAGE WRITE command consists of an inte-

grated PAGE ERASE cycle followed by a PAGE PROGRAM cycle.

The memory is organized as 2 sectors, each containing 256 pages. Each page is 256

bytes wide. The entire memory can be viewed as consisting of 512 pages, or 131,072

bytes.

The memory can be erased one page at a time using the PAGE ERASE command or one

sector at a time using the SECTOR ERASE command.

To meet environmental requirements, Micron offers the M45PE10 in RoHS-compliant

packages, which are also lead-free.
