Chapter 1: SP605 Evaluation Board

14. IIC Bus

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
