The M25P80 is an 8Mbit low voltage serial flash memory with a 40MHz SPI bus interface. Its features include: 8Mbit of flash storage, page programming (up to 256 bytes) in 1.4ms (typical), sector erase (512 Kbit) in 1s (typical), bulk erase (8 Mbit) in 10s (typical), 2.7 to 3.6V single supply voltage, SPI bus compatible serial interface, 40MHz clock rate (maximum), deep power-down mode 1µA (typical), and electronic signature (13h).
The M25P80 serial flash memory provides 8 Mbit (1M × 8) storage, organized into 16 sectors of 256 pages each. Each page holds up to 256 bytes, allowing fast page‑program operations. The device operates from a single 2.7 V to 3.6 V supply and communicates via a standard SPI bus up to 40 MHz.
Key features include page programming in as little as 1.4 ms, sector erase in about 1 s, bulk erase in 10 s, deep power‑down mode with ultra‑low current consumption, and an electronic signature for identification. The datasheet details pin configurations, timing diagrams, electrical characteristics, and package dimensions for the VDFPN8, SO8, and SO16 packages.
