TTTech, a supplier of solutions in the field of time-triggered technologies, and ON Semiconductor, have agreed to join forces to develop a controller for TTP (Time-Triggered Protocol). This controller is targeted at cross-industry applications and especially the aerospace market. TTTech and ON Semiconductor will offer the new high-speed data bus controller with up to 25 Mbit/s per channel for aerospace projects that demand the robustness of the TTP technology as well as the reliability and longevity of ON Semiconductor products. The device is intended to be compatible with the TTP controller AS8202NF available from austriamicrosystems and will have the same pinout. This will ensure the sourcing of TTP controllers from two suppliers. In addition, the ON Semiconductor TTP device will offer a configurable 8B10B coding at communication speeds of 10 Mbit/s using RS-485 physical layer. The data rate for TTP communication over RS-485 is doubled compared to previous technologies while maintaining DC-free operation according to aerospace requirements.

TTP communication controllers offer a maximum level of fault tolerance, safety, and availability for aerospace applications. The TTP chip IP is designed to meet aerospace requirements in compliance with DO 254/DO 178B Level A. They are successfully applied in modular and distributed control systems in aerospace programs such as the Airbus A380, Lockheed Martin F-16 and in the Boeing 787 Dreamliner.
