Lattice Semiconductor
master serial clock is 2.5MHz. Table 2-10 lists all the available Master Serial Clock frequencies. When a different
Master Serial Clock is selected during the design process, the following sequence takes place:
1. User selects a different Master Serial Clock frequency for configuration.
2. During configuration the device starts with the default (2.5MHz) Master Serial Clock frequency.
3. The clock configuration settings are contained in the early configuration bit stream.
4. The Master Serial Clock frequency changes to the selected frequency once the clock configuration bits are
For further information on the use of this oscillator for configuration, please see details of additional technical docu-
mentation at the end of this data sheet.

Density Shifting
The LatticeXP family has been designed to ensure that different density devices in the same package have the
same pin-out. Furthermore, the architecture ensures a high success rate when performing design migration from
lower density parts to higher density parts. In many cases, it is also possible to shift a lower utilization design tar-
geted for a high-density device to a lower density device. However, the exact details of the final resource utilization
will impact the likely success in each case.
