6.16 Inter-Integrated Circuit (I2C)
The inter-integrated circuit (I2C) module provides an interface between the DM368 and other devices
compliant with Philips Semiconductors Inter-IC bus (I²C-bus) specification version 2.1 and connected by
way of an I²C-bus. External components attached to this 2-wire serial bus can transmit/receive up to 8-bit
data to/from the device through the I2C module.
The I2C port supports:
• Compatible with Philips I2C Specification Revision 2.1 (January 2000)
• Fast Mode up to 400 Kbps (no fail-safe I/O buffers)
• Noise Filter to Remove Noise 50 ns or less
• Seven- and Ten-Bit Device Addressing Modes
• Master (Transmit/Receive) and Slave (Transmit/Receive) Functionality
• Events: DMA, Interrupt, or Polling
For more detailed information on the I2C peripheral, see the Documentation Support section for the device
Inter-Integrated Circuit (I2C) Module Reference Guide.
