GENERAL DESCRIPTIONS

The GD25LQ40E/20E (4M/2M-bit) Serial flash supports the standard Serial Peripheral Interface (SPI), and the Dual/Quad 

SPI: Serial Clock, Chip Select, Serial Data I/O0 (SI), I/O1 (SO), I/O2 (WP#), I/O3 (HOLD#). The Dual I/O data is 

transferred with speed of 266Mbit/s, and the Quad I/O data is transferred with speed of 532Mbit/s.
