AS8202B
Description
The AS8202B munication controller is an integrated device supporting serial munication according to the TTP specification version 1.1. It performs all munication tasks such as reception and transmission of messages in a TTP cluster without interaction of the host CPU. TTP 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 synchronization
- Consistent membership service with small delay
- Masking of single faults
2 Key Features
- Dual-channel controller for redundant data transfers
- Dedicated controller supporting TTP (time-triggered protocol class C standardized in SAE 6003)
- Suited for dependable distributed real-time systems with guaranteed response time
- Asynchronous data rate up to 4 Mbit/s (MFM/Manchester)
- Synchronous data rate 20 to 25 Mbit/s
- Bus interface (speed, encoding) for each...
