3.3V Uniform Sector

Dual and Quad Serial Flash

GD25B127D

4. DEVICE OPERATION

SPI Mode

Standard SPI

The GD25B127D features a serial peripheral interface on 4 signals bus: Serial Clock (SCLK), Chip Select (CS#),

Serial Data Input (SI) and Serial Data Output (SO). Both SPI bus mode 0 and 3 are supported. Input data is latched on the

rising edge of SCLK and data shifts out on the falling edge of SCLK.

Dual SPI

The GD25B127D supports Dual SPI operation when using the

“Dual Output Fast Read” and “Dual I/O Fast Read”

(3BH and BBH) commands. These commands allow data to be transferred to or from the device at twice the rate of the

standard SPI. When using the Dual SPI command the SI and SO pins become bidirectional I/O pins: IO0 and IO1.

Quad SPI

The GD25B127D supports Quad SPI operation when using

the “Quad Output Fast Read”,” Quad I/O Fast Read”,

“Quad I/O Word Fast Read” (6BH,EBH,E7H)commands. These commands allow data to be transferred to or from the device

at four times the rate of the standard SPI. When using the Quad SPI command the SI and SO pins become bidirectional I/O

pins: IO0 and IO1.
