STMicroelectronics has extended its portfolio of radiation-hardened (rad-hard) devices by adding a series of LVDS drivers, receivers, and multiplexers carrying the US 300krad QML-V qualification. LVDS (Low-voltage differential signaling) is a technical standard that specifies electrical characteristics of a differential, serial communication protocol. Both the United States' Qualified Manufacturer List (QML) Class V and ESCC (European Space Components Coordination) are considered to be the highest qualification for space integrated circuits.
ST's new rad-hard devices exceed the performance of competing solutions, combining proven 130nm process technology with dedicated chip architecture and layout rules to achieve superior radiation-immunity and electrical characteristics. The development has been supported by the French Centre National d'Etudes Spatiales (CNES) and the European Space Agency (ESA) for use in future commercial and government satellite projects. The ST devices are also QML-V qualified, enabling approval for use by space agencies and contractors worldwide.
