7.11.2 DDR3 Memory Controller Electrical Data/Timing
The DDR3 Implementation Guidelines Application Report in 2.9 ‘‘Related Documentation from Texas
Instruments’’ on page 66 specifies a complete DDR3 interface solution as well as a list of compatible DDR3 devices.
The DDR3 electrical requirements are fully specified in the DDR3 Jedec Specification JESD79-3C. TI has performed
the simulation and system characterization to ensure all DDR3 interface timings in this solution are met; therefore,
no electrical data/timing information is supplied here for this interface.
Note—TI supports only designs that follow the board design guidelines outlined in the application report.
7.12 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 SoC through
the I²C module.
7.12.1 I²C Device-Specific Information
The TMS320C6670 device 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 C6670 may be used by the DSP to control local peripheral ICs (DACs, ADCs, etc.) or may
be used to 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
