M25P80-VMN6 Datasheet - Numonyx -> Micron

Description
The M25P80 is an 8 Mbit (1 Mbit × 8) Serial Flash memory, with advanced write protection mechanisms, 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.

FEATUREs
■ SPI bus compatible serial interface
■ 75 MHz Clock rate (maximum)
■ 2.7 V to 3.6 V single supply voltage
■ 8 Mbit of Flash memory
■ Page Program (up to 256 bytes) in 0.64 ms (typical)
■ Sector Erase (512 Kbit) in 0.6 s (typical)
■ Bulk Erase (8 Mbit) in 8 s (typical)
