6.12 I²C Peripheral
The inter-integrated circuit (I²C) module provides an interface between DSP 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 DSP through the I²C module.
6.12.1 I²C Device-Specific Information
The C6654 and C6652 devices includes an I²C peripheral module.
NOTE
When using the I²C module, ensure there are external pullup resistors on the SDA and SCL
pins.
The I²C modules on the C6654 and C6652 may be used by the DSP to control local peripheral ICs (DACs,
ADCs, and so forth.) or may be used to communicate with other controllers in a system or to implement a
user interface.
The I²C port is compatible with Philips I²C specification revision 2.1 (January 2000) and supports:
• Fast mode up to 400 Kbps (no fail-safe I/O buffers)
• Noise filter to remove noise 50 ns or less
• 7-bit and 10-bit device addressing modes
• Multimaster (transmit/receive) and slave (transmit/receive) functionality
• Events: DMA, interrupt, or polling
• Slew-rate limited open-drain output buffers
Figure 6-23 shows a block diagram of the I²C module.
