I2C Slave

Model No. IPRI2CSSFP001

Rating: Not Rated Yet



The I²C slave IP is fully synthesizable core and compatible with Phillips I²C standard. The IP uses I²C Bus Protocol which helps maximize the hardware efficiency and minimize the interfaces.

The I²C Slave IP Core is provided as Altera SOPC Builder ready component and integrates easily into any SOPC Builder generated system.

Block Diagram:


  • Data transfers up to 100 Kbps in standard mode and up to 400 Kbps in fast-mode
  • Uses two wires to transfer information between devices
  • Bi-directional data transfer
  • 7-bit addressing format
  • Fixed data width of 8 bits
  • Data transfer in multiples of bytes
  • Interrupt or bit-polling driven byte-by-byte data transfer
  • Start/Stop detection
  • Operates from a wide range of input clock frequency
  • Fully synthesizable
