W - Winbond 25X - SPI Flash with 4KB sectors/64Kbyte blocks, dual output 16A - 16Mbit / 2M-byte V - Supply Voltage 2.7 to 3.6V S - Package Type : 8pin SOIC 150-mil I - Temperature Range: Industrial (-40'C ~ 85'C) G - Environment: Green Package (Lead-free, RoHS Compliant, Halogen-free (TBBA), Antimony-Oxie-free)
datasheet: W25X16A.pdf (1.3 MB)
Note: can use Bus Ninja or Bus Pirate and FlashROM - ISP is possible, so long as no other devices on the SPI bus are trying to access the device (in that case, you might want to cut Vcc to the FPGA or the regulator for it).
