GENERAL DESCRIPTION
The GD25LQ16 (16M-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.
