 Newbridge Networks primarily acquired Calmos Microsystems for its single chip high-speed public key data encryption system, which became a selling point for Newbridge Networks systems to the U.S. federal government.The rest of the original Calmos Product line though revenue generating and profitable was not a major reason for the acquisition, these products continued to be sources of revenue well after the division was spun out as Tundra, most notably this include the 8085 variant which was sold as late as 1999.In December 1995, Newbridge Microsystems assets were sold into a new Corporate entity known as Tundra Semiconductor.
