1.8V Uniform Sector

Dual and Quad Serial Flash

GD25LE256D

Fast Read (0BH) in QPI mode

The Fast Read command is also supported in QPI mode. In QPI mode, the number of dummy clocks is configured by

the

“Set Read Parameters (C0H)” command to accommodate a wide range application with different needs for either

maximum Fast Read frequency or minimum data access latency. Depending on the Read Parameter Bits P[5:4] setting, the

number of dummy clocks can be configured as either 4/6/8/8.
