S25FL127SABMFI000 is a S25FL127S non-volatile serial peripheral interface (SPI) flash memory IC using MIRRORBIT™ technology - that stores two data bits in each memory array transistor, eclipse architecture - that dramatically improves program and erase performance, 65nm process lithography. This device connects to a host system via an SPI. Traditional SPI single bit serial input and output (single I/O or SIO) is supported as well as optional two bit (dual I/O or DIO) and four bit (quad I/O or QIO) serial commands. By using FL-S device at the higher clock rates supported, with QIO command, the instruction read transfer rate can match or exceed traditional parallel interface, asynchronous, NOR flash memories while reducing signal count dramatically. It offers a high density coupled with the flexibility and fast performance required by a variety of embedded applications. It is ideal for code shadowing, XIP, and data storage.
