Description
Summary
This work presents a radiation hardened integrated circuit (RHIC) that replaces with a single chip solution many of the electrical, electronic and electromechanical (EEE) components used on satellite subsystems such as remote interface, remote terminal and instrument control units (RIU/RTU/ICU). The presented RHIC is designed for acquiring the telemetries (TM) and generating the telecommands (TC) from and for other subsystems of the satellite platform. Replacing the classical discrete implementation by this TM/TC ASIC will entail volume, weight and price reduction of the RIUs/RTUs and ICUs subsystems and hence the overall satellite platform. To minimize risks and time development, several analogue IPs from the Cosmic Vision projects will be reused (and even slightly tailored if required) for this development. Communications with TM/TC RHIC will be by means of a redundant SPI bus. Telemetries shall be acquired with at least 11 effective bits resolution from 56/28 [0; 10] V single ended / [-10; 10] V differential channels, limited in band up to 50 kHz. Telecommands shall allow bi-level, single pulse, pulse-width modulation and voltage monitoring alarm functionalities with frequencies from 100Hz to 10MHz. TM/TC RHIC will be implemented using version 5.6 of DARE180U libraries (provided by IMEC) based on UMC L180 technology.
