AT7909E
1. Description
The AT7909E is an integrated device providing on-board telemetry and telecommand
services via standardized interfaces.
The AT7909E is mainly an integrated telecommand decoder and telemetry encoder
device. It can operate in stand-alone mode, without requiring any programming or
support from an on-board computer. It can also operate in tight integration with a com-
puter, featuring fast communication links for both commanding and data transfer. The
different capabilities of the AT7909E can work together, or separately when only part
of the functionality is required in a system, e.g. a telecommand decoder or telemetry
encoder only.
The AT7909E was designed by Saab Space, Sweden (ESTEC / contract no.
16064/02/NL/FM), who will bring the technical answers to all questions relative to
functionality through Atmel hot line [e-mail].
This document shall be read in conjunction with Saab Space 'SCTMTC ASIC user's
manual reference P-ASIC-NOT-00122-SE'.
