Cypress Semiconductor NOR 256Mbit CFI, Parallel, SPI Flash Memory 8-Pin WSON, S25FS256SAGNFI001

TheS25FS-S family connects to a host system via a Serial Peripheral Interface (SPI). Traditional SPI single bit serial input and output (Single I/O or SIO) is supported as well as optional 2-bit (Dual I/O or DIO) and 4-bit wide Quad I/O (QIO) or Quad Peripheral Interface (QPI) serial commands. This multiple width interface is called SPI Multi-I/O or MIO. In addition, there are Double Data Rate (DDR) read commands for QIO and QPI that transfer address and read data on both edges of the clock.
