Description

The TTP/C-C1 communications controller is the first integrated device supporting serial communication according to the TTP/C specification (time triggered protocol class C). It performs all communications tasks such as reception and transmission of messages in a TTP/C cluster without interaction of the host CPU. TTP/C provides mechanisms that allow the deployment in high-dependability distributed real time systems. It provides the following services:

· predictable transmission of messages with minimal jitter

· fault-tolerant distributed clock synchronisation

· consistent membership service with small delay

· masking of single faults

Key Features

· First dedicated controller supporting TTP/C (time triggered protocol class C)

· Device for building up TTP/C nodes in a TTP/C local area networks (clusters).

· Suited for dependable distributed real-time systems with guaranteed response time

· application examples:

   automotive: braking, steering, vehicle dynamics control, drive train control

   industry: air plane flap control, rail way points
