AT7911E Description
The AT7911E provides an interface between three SpaceWire links according to the SpaceWire standard ECSS-E-50-12A specification and a data processing node consisting of a Control Processing Unit and a munication data memory. The AT7911E was designed by EADS Astrium in Germany under the name 'SMCS332SpW" for "Scalable Multi-channel munication Subsystem for SpaceWire". It is manufactured using the SEU hardened cell...
AT7911E Key Features
- Also known as SMCS332SpW
- 3 identical bidirectional SpaceWire links allowing
- full duplex munication
- transmit rate from 1.25 up to 200 Mbit/s in each direction Derived from the TSS901E-SMCS332 triple IEEE 1355 high speed
- Known anomalies of the TSS901E chip corrected
- Slightly different startup behavior munication Memory Interface (I)
- autonomous accesses to a munication memory HOst Control Interface (HOCI)
- gives read/write accesses to the AT7911E configuration registers
- gives read/write accesses to the SpaceWire channels Arbitration unit
- Allows two AT7911E to share one Dual Port RAM without external arbitration Scalable databus width
