3.1. Differences between IM-LT3 and IM-LT1

The IM-LT3 Interface Module is similar to the IM-LT1 Interface Module. The IM-LT1 allows the Integrator system to access resources on the Logic Tiles, but it does not have an FPGA fitted. The differences between the two modules are listed in Table 3.1. For more information on the IM-LT1, see the Integrator/IM-LT1 User Guide.


The signal names for the same pin differ between the IM-LT1 and IM-LT3 because the IM-LT1 does not have an FPGA fitted.
