I3C Dual-Role Master

The I3C Dual-Role Master controller is a highly configurable I3C master that can be used in microcontroller based environments to provide I3C connectivity to any device. It contains master capabilities as well as the same features as the I3C Advanced Slave. It can be configured in a number of different ways to allow the core to use the minimum amount of logic to reduce both area (cost) and power.

APPLICATIONS

  • Mechanical sensing (Gyroscopes, MEMS, etc.)
  • Environmental sensing (Light, pressure, temperature, humidity, etc.)
  • Biometrics (Fingerprinting, glucose, heart rate, breathalyzer, etc.)
  • Communication (Near-field sensors, infrared remotes, etc.)
