120 pin PQFP Package

The TTP/C-C1 communications controller AS8201 is the first integrated device supporting serial communication according to the TTP/C specification (time triggered protocol class C). AS8201 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. AS8201 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
