NOTE
TI supports only designs that follow the board design guidelines outlined in the application
report.
11.12 I²C Peripheral
The Inter-Integrated Circuit (I²C) module provides an interface between SoC and other devices compliant
with Philips Semiconductors (now NXP Semiconductors) Inter-Integrated Circuit bus specification version
2.1. 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.
11.12.1 I²C Device-Specific Information
The device includes multiple I²C peripheral modules.
NOTE
When using the I²C module, ensure there are external pullup resistors on the SDA and SCL
pins.
The I²C modules on the TCI6630K2L may be used by the SoC to control local peripheral ICs (DACs,
ADCs, etc.), communicate with other controllers in a system, or to implement a user interface.
The I²C port supports:
• Compatibility 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 of 50 ns or less
• 7-bit and 10-bit device addressing modes
• Multi-master (transmit/receive) and slave (transmit/receive) functionality
• Events: DMA, interrupt, or polling
• Slew-rate limited open-drain output buffers
Figure 11-44 shows a block diagram of the I²C module.
