1.We can support W25X(Dual SPI) flash. You can refer to the following topic for details.

http://bbs.espressif.com/viewtopic.php?f=7&t=25


2.With regard to N25Q016A,we haven't tested this flash before, but ESP8266 should be able to support.
As for voltage range of power supply of N25Q016A is from 1.7~2.0 V, you should connect IO power supply(VDDPST Pin11/Pin17) of ESP8266 to 1.8V. And then voltages of all IO interfaces of ESP8266 will be 1.8V.

Please be noted that chip_en(Pin7) of ESP8266 should be better connected to VDD33.

Any more questions, please feel free to let us know.

Thanks.

It is the smallest SPI flash I could find, with a 2x2.8mm package. The data sheet lists dual and quad read and I/O, but I don’t know how standard that is or whether there are sometimes quirks like that bug with Winbond W25X.
