M25PXX Figure 3. SO8 and VDFPN Connections SUMMARY DESCRIPTION The M25Pxx is a 512Kbit to 32Mbit (2M x 8) Serial Flash Memory, with advanced write protection mechanisms, accessed by a high speed SPI-com- patible bus. The memory can be programmed 1 to 256 bytes at a time, using the Page Program instruction. M25Pxx The memory is organized as a number of sectors, each containing 256 or 128 pages. Each page is SV1 8 CC 256 bytes wide. Q 2 7 HOLD The whole memory can be erased using the Bulk W 3 6 C Erase instruction, or a sector at a time, using the V 4 5 D SS Sector Erase instruction.
