[> Intro

LiteI2C provides a small footprint and configurable I2C core.

LiteI2C is structured and operates similar to LiteSPI.

LiteI2C is part of LiteX libraries whose aims are to lower entry level of complex FPGA cores by providing simple, elegant and efficient implementations of components used in today's SoC such as Ethernet, SATA, PCIe, SDRAM Controller...

Using Migen to describe the HDL allows the core to be highly and easily configurable.

LiteI2C can be used as LiteX library.
