SUMMARY DESCRIPTION

The M25P05 is a 512 Kbit (64K x 8) Serial Flash Memory, with advanced write protection mechanisms, accessed by a high speed SPI-compatible bus.

The memory can be programmed 1 to 128 bytes at a time, using the Page Program instruction.

The memory is organized as 2 sectors, each containing 256 pages. Each page is 128 bytes wide.

Thus, the whole memory can be viewed as consisting of 512 pages, or 65536 bytes.

The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction.

FEATURES SUMMARY

This device is now designated as “Not for New Design”. Please use the M25P05-A in all future designs (as described in application note AN1511).
