1 Gbit (128 Mbyte) S79FL01GS Dual-Quad SPI NOR Flash Memory Datasheet
The S79FL01GS 1Gb device connects two Quad I/O SPI devices with a single CS# resulting in an eight bit I/O data path. This Byte I/O interface is called Dual-Quad I/O. This device connects to a host system via a Serial Peripheral Interface (SPI). Traditional SPI single bit serial input and output (IO1 and IO5) is supported as well as four-bit (Quad I/O or QIO) serial commands. This multiple width interface is called SPI Multi-I/O or MIO. In addition, the S79FL01GS device adds support for Double Data Rate (DDR) read commands for QIO that transfers address and read data on both edges of the clock.
