Features
⢠Also known as SMCS332SpW
⢠3 identical bidirectional SpaceWire links allowing
â full duplex communication
â transmit rate from 1.25 up to 200 Mbit/s in each direction
⢠Derived from the TSS901E-SMCS332 triple IEEE 1355 high speed controller
â Known anomalies of the TSS901E chip corrected
â Slightly different startup behavior
⢠COmmunication Memory Interface (COMI)
â autonomous accesses to a communication memory
⢠HOst Control Interface (HOCI)
â gives read/write accesses to the AT7911E configuration registers
â gives read/write accesses to the SpaceWire channels
⢠Arbitration unit
â Allows two AT7911E to share one Dual Port RAM without external arbitration
⢠Scalable databus width
â 8/16/32 bit width available
â allows flexible integration with any CPU type
⢠Allows Little endian and Big endian configuration
