1. Description The SpW-10X SpaceWire routing switch is capable of connecting many nodes, providing a
means of routing packets between the nodes connected to it. It comprises eight SpaceWire link
interfaces and a routing matrix. The routing matrix enables packets arriving at one link interface
to be transferred to and sent out of another link interface on the routing switch.
The AT7910E was designed by Austrian Aerospace (Austria) and the University of Dundee
(Scotland). It is manufactured using the SEU hardened cell library from Atmel MH1RT CMOS
0.35µm radiation hardened sea of gates technology.
For any technical question relative to the functionality of the AT7910E please contact Atmel tech-

This document must be read in conjunction with the University of Dundee “SpaceWire Router
SpW-10X User Manual” available at
The SpaceWire router comprises the following functional logic blocks:
• Eight SpaceWire bi-directional serial ports.
• Two external parallel input/output ports each comprising an input FIFO and an output FIFO.
• A non-blocking crossbar switch connecting any input port to any output port.
• An internal configuration port accessible via the crossbar switch from the external parallel
input/output port or the SpaceWire input/output ports.
• A routing table accessible via the configuration port which holds the logical address to output
port mapping.
• Control logic to control the operation of the switch, performing arbitration and group adaptive
• Control registers than can be written and read by the configuration port and which hold
control information e.g. link operating speed.
• An external time-code interface comprising tick_in, tick_out and current tick count value
• Internal status/error registers accessible via the configuration port
• External status/error signals
A block diagram of the routing switch is given in the following figure:
