GD25Q16 - 2MB SPI Flash in 8-Pin SOIC package. These little chips are like miniature SSD drives for your electronics. When you don't need something with as much storage as a micro SD card, but an EEPROM is too small, SPI (or QSPI) Flash chips give you on-the-order-of megabytes, with little cost and complexity. We use these chips all the time on our CircuitPython boards to let folks store code and assets like animations, fonts, images, configurations, audio clips, etc!
The GD25Q40C / GD25Q41B (4M-bit) Serial flash supports the standard Serial Peripheral Interface (SPI), and supports the Dual/Quad SPI: Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO), I/O2 (WP#), and I/O3 (HOLD#). The Dual I/O data is transferred with speed of 240Mbits/s and the Quad I/O & Quad output data is transferred with speed of 480Mbits/s.

Sep 26, 2018 · The Pine64 Rock64 board comes with a GigaDevice GD25Q128CSIG or GD25Q127CSIG chip, which is a 128 Mbit SPI NOR flash chip that supports the JEDEC read-ID command. This patch enables the SPI controller and adds a device node for the flash chip using the generic "jedec,spi-nor" comaptible.
Read and write sequences are the same as in regular SPI systems, except that the chip selects must be set up beforehand. PC0 then goes low, the read/write operation is executed, and PC0 returns ...
