The SP605 implements three IIC bus interfaces at the FPGA.

The MAIN IIC bus hosts four items:

•FPGA U1 Bank 1 "MAIN" IIC interface

•8-Kb NV Memory U4

•FMC LPC connector J2

•2-Pin External Access Header J45

The DVI IIC bus hosts two items:

•FPGA U1 Bank 2 DVI IIC interface

•DVI Codec U31 and DVI connector P3 The SFP IIC bus hosts two items:

•FPGA U1 Bank 0 SFP IIC interface

•SFP module connector P2

The SP605 IIC bus topology is shown in Figure 1-11.
