Electronic components and systems are highly susceptible to damage and malfunctions caused by ionizing radiation. These environments may be encountered in high altitude flight and in outer space, as well as in the vicinity of nuclear reactors or devices. In order to ensure the reliable operation of electronics subjected to such environments, a variety of techniques can be employed to make them radiation tolerant. This article will highlight the value of the various radiation mitigation technologies available.

DDC introduces a high performance DSP based family of programmable, turnkey motor controllers designed to precisely control the position, torque, and speed of 3-phase BLDC motors, with maximum reliability. The high power density 80V/30A rated MC-5000 series BLDC motor controller operates over an extended -40°C to +105°C temperature range, and is available in configurations to support a wide variety of motors.

• Reduces In-House Development Risk & Time-to-Markets – Compact, high power density, fully integrated solution
• Comprehensive programmability – Enables one motor controller to be used with a variety of motors across multiple application platforms, saving inventory and operations costs
• High System Reliability – High MTBF

DDC is pleased to announce that our Rad Hard SCS750 Single Board Computers for Space will be deployed on the ESA Euclid satellite scheduled for launch in 2021. Euclid employs several of DDC’s SCS750 single board computers onboard, serving as key elements within the spacecraft’s critical imaging and data acquisition systems.

• Proven Reliability – TRL-9 solution, deployed on the most critical missions, provides a 1 in 80 year board level SEE rate (GEO), TID > 100krad(Si), and SEL immunity. Since DDC began providing its radiation hardened RAD-PAK components and single board computer solutions more than 20 years ago, we have experienced zero failures in space!
• Optimized Performance – Seamless triple-redundant error correction processing, coupled with error-corrected high-density Flash, SDRAM and EEPROM memory, ensures incorrect transactions are never generated; High speed processing (200-1800 MIPS), with low power consumption (7-30W typical).
