Dual and Quad Serial Flash
2. GENERAL DESCRIPTION
GD25Q40C
The GD25Q40C (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.
