Lattice Sentry I2C Filter IP Core

Invisible Relay to Protect All Slave Devices Against Malicious Traffic

SMBus Relay with filter (named I2C filter in this document) is designed to function as an invisible relay from the point of view of both Controller and Target devices on the bus.

Resource Utilization details are available in the IP Core User Guide.

Features

  • Provides four interfaces, namely, AHB Lite, SMBus controller, SMBus target and Interrupt.
  • Connected between a single controller (Primary) and multiple target (Secondary) devices.
  • Protects the secondary devices from malicious traffic generated from the controller.
  • Does not violate SMBus protocol and is transparent between the Primary and Secondary devices.
  • Allows all the Read access.
