Micron M25P80 Serial Flash Embedded Memory
Functional Description
Functional Description
The M25P80 is an 8Mb (1Mb x 8) serial Flash memory device with advanced write pro-
tection mechanisms accessed by a high speed SPI-compatible bus. The device supports
high-performance commands for clock frequency up to 75 MHz.
The memory can be programmed 1 to 256 bytes at a time using the PAGE PROGRAM
command. It is organized as 16 sectors, each containing 256 pages. Each page is 256
bytes wide. Memory can be viewed either as 4096 pages or as 1,048,576 bytes. The entire
memory can be erased using the BULK ERASE command, or it can be erased one sector
at a time using the SECTOR ERASE command.
This data sheet details the functionality of the M25P80 device based on 110nm process.
