I2C PHY & Controller

DTI I2C Controller provides the logic consistent with NXP I2C specification to support the communication of low-speed integrated circuits through I2C bus.
The IP facilitates software controllable by application processor through industry-standard AMBA interface. The bus interface is flexible and easily integrated into APB, AHB or AXI system bus.

Compliant with the following specifications:

• I2C Bus Specification Version 6.0
• AMBA, Advanced Peripheral Bus (APB) Specification Version 2.0
• AMBA, Advanced High-performance Bus (AHB) Specification Version 2.0
• AMBA, Advanced eXtensibale Bus (AXI) Specification Version 4.0
• AMBA, Advanced eXtensibale Lite Bus (AXI-Lite) Specification Version 4.0

DTI I2C Controller supports:

• Master only operation
• Slave only operation
• Master and slave operation
• 5 speed modes:
  • Standard speed mode (up to 100 Kbps)
  • Fast speed mode (up to 400 Kbps)
  • Fast speed mode plus (up to 1 Mbps)
  • High speed mode (up to 3.4 Mbps)
  • Ultra fast speed mode (up to 5 Mbps)
• Singled or combined message protocol
• 7-bit or 10-bit addressing
• Input spike suppression
• Clock synchronization
• Slave clock stretching
