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.
 

"Since we released our first TTP product in 1998, the TTP controller family has greatly increased our market strength in the field of aerospace applications."
