IC Engineering has been in business since 1986, and offers standard products (such as the Modem Security Enforcer and ARONTS) as well as custom product development. Our emphasis is on voice and data telecommunications systems utilizing microcontroller technology.

Depending on requirements, we can modify the firmware and hardware of our existing proprietary platforms to address specific applications, or design entirely new hardware and software when necessary. Complete turnkey products, engineering plans for submission to outside manufacturers, and subsystem design can be provided. Joint development ventures are welcomed.
