AT7911E

Features www.DataSheet4U.com 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 3V to 3.6V 4.5V to 5.5V – Temperature - 55° C to +125° C Maximum Power consumption – At 3.6V with a 15MHz clock : 0.4 W – At 5.5V with a 25 MHz clock : 1.7 W Radiation Performance – Total dose tested successfully up to 50 Krad (Si) – No single event latchup below a LET of 80 MeV/mg/cm2 ESD better than 2000V Quality Grades : – QML-Q or V with SMD Package : 196 pins MQFPL Mass : 12grams Triple SpaceWire links High Speed Controller AT7911E 1.
