Features
• Also known as SMCS332SpW
•
3 identical bidirectional SpaceWire links allowing
– full duplex communication
– transmit rate from 1.25 up to 200 Mbit/s in each direction
Derived from the TSS901E-SMCS332 triple IEEE 1355 high speed controller
– Known anomalies of the TSS901E chip corrected
– Slightly different startup behavior
COmmunication Memory Interface (COMI)
– autonomous accesses to a communication memory
HOst Control Interface (HOCI)

Triple
SpaceWire links
High Speed
Controller
– 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
– 8/16/32 bit width available
– allows flexible integration with any CPU type
Allows Little endian and Big endian configuration
