AT7911E_14 Datasheet, PDF (1/22 Pages) ATMEL Corporation – 3 identical bidirectional SpaceWire links allowing

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)
– 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
• Performance
– At 3.3V: 100 Mbit/s full duplex communication in each direction
– At 5V: 200 Mbit/s full duplex communication in each direction
• Operating range
– Voltages
