  • Isolator with complementary configurable memory
    Patent number: 8441325
    Abstract: An isolator that includes first and second substantially identical circuitry galvanically isolated from each other and each having at least one communications channel thereon for communicating signals across an isolation boundary therebetween and each of said first and second circuitry having configurable functionality associated with the operation thereof. A coupling device is provided for coupling signal across the isolation boundary between the at least one communication channels of the first and second circuitry. First and second configuration memories are provided, each associated with a respective one of the first and second circuitry. First and second configuration control devices are provided, each associated with a respective one of the first and second circuitry and each configuring the functionality of the associated one of the first and second circuitry.
