GENERAL DESCRIPTION
GD25LQ256D
The GD25LQ256D (256M-bit) Serial flash supports the standard Serial Peripheral Interface (SPI), and supports the
Dual/Quad SPI and QPI mode: 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.

Note:
1. CS# must be driven high if chip is not selected. Please don’t leave CS# floating any time after power is on.
2. The NC pin/ball is not connected to any internal signal. It is OK to connect it to the system ground (GND) or leave it
floating.
