The TTPController is an integrated CMOS device which implements the functionalities and features of the SAE AS6003 standard established back in 2011. It is designed using our DO 254-compliant C2NF chip IP and is commercially available in its third generation. Its datasheet is available in the Downloads section below.
Application fields
Standard TTP® controllers are commercially available from TTTech since 1999. Although the open TTP standard was not developed for a specific application field, it clearly targets safety-critical applications due to built-in redundancy and fault-tolerance mechanisms as well as the development guidelines followed. Main use is in aviation (see press release) for modular/distributed real-time control systems. See our case studies for Honeywell MAC and the Boeing 787 Dreamliner. The TTP controller is also used in fly-by-wire systems on the Bombardier Global 7500/8000, Embraer Legacy and Praetor, and the Airbus A220."
Certified off-the-shelf communication controller
The TTP chip IP and supporting embedded software were designed to meet the stringent requirements of RTCA DO-254 / EUROCAE ED-80 and DO-178B up to the highest Design Assurance Level (DAL A) and got certified in a long list of projects. TTTech supports new projects with certification data packages and highly experienced engineers.
