Single Chip Telemetry and Telecommand 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 computer, 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 assp-applab.hotline@nto.atmel.com. This document shall be read in conjunction with Saab Space 'SCTMTC ASIC user's manual reference P-ASIC-NOT-00122-SE'.
