5 / 35 page 5/41 M25P80 SUMMARY DESCRIPTION The M25P80 is a 8 Mbit (1M 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 16 sectors, each con- taining 256 pages. Each page is 256 bytes wide. Thus, the whole memory can be viewed as con- sisting of 4096 pages, or 1,048,576 bytes. The whole memory can be erased using the Bulk Erase instruction, or a sector at a time, using the Sector Erase instruction. Figure 2. Logic Diagram Table 1. Signal Names Figure 3. VDFPN and SO8 Connections Note: 1. There is an exposed die paddle on the underside of the MLP8 package. This is pulled, internally, to VSS, and must not be allowed to be connected to any other voltage or signal line on the PCB. 2.
