AT7913E Advanced Information
1. Description
The SpaceWire Remote Terminal Controller (RTC) device is a bridge between the
SpaceWire network and the CAN bus, providing a fully integrated system. Additional
features are provided to carter for autonomy of remote terminals and to relieve the cen-
tral processing chain of repetitive standard acquisitions and management duties. The
SpaceWire-RTC device can be used both in non-intelligent nodes and in nodes with
local intelligence.
The SpaceWire-RTC device includes an embedded microprocessor, a CAN bus control-
ler, ADC/DAC interfaces for analogue acquisition/conversion, standard interfaces and
resources (UARTs, timers, general purpose input output).
The SpaceWire-RTC device can be operated stand-alone or with a number of external
devices such as SRAM, PROM and FIFO memories, ADC and DAC converters. The
device can be managed locally by the on-chip processor, or remotely via its SpaceWire
link interfaces. SpaceWire-RTC device can operate as a single-chip system, with soft-
ware being uploaded to its on-chip memory via the SpaceWire link interface, forming a
compact solution for remotely controlled applications. Or it can operate in a full-size sys-
tem, with software being decompressed from local PROM and executed from multiple
fast and wide SRAM memory banks. The device provides scalability in terms of use of
external devices and operating frequency.
