Cosmic radiation is an invisible threat that can be countered with laser-driven accelerator technology, says Manuel Hegelich. The space industry faces an invisible enemy that threatens every mission from Earth orbit to Mars and beyond: cosmic radiation. Space radiation Modern electronics face unprecedented vulnerability to space radiation. As transistors shrink below 10nm, even low-energy particles can cause single-event effects (SEEs). ...
Teledyne e2v has introduced engineering models of its forthcoming 16Gbyte radiation-tolerant DDR4 memory. “With the release of our engineering model, system architects can begin early validation, preparing for a transition to flight-qualified versions,” said Teledyne marketing manager Thomas Guillemain. The memory measures 15 x 20 x 1.92mm and it pad-compatible with the company’s earlier 4 and 8Gbyte DDR4 ICs which ...
Microchip has achieved JANSF qualification for a 100V n-channel mosfet to to 300krad (Si) TID (total ionising dose), and completed its family of radiation-hardened power mosfets to MIL-PRF-19500/746 slash-sheet specification. “The JANS qualification represents the highest level of screening and acceptance requirements, ensuring the superior performance, quality and reliability of discrete semiconductors for aerospace, defense and spaceflight applications,” according to ...
Infineon Technologies has introduced a radiation-hardened 512Mbit QSPI NOR flash memory for space applications and other extreme environments. “The device offers a 133MHz quad serial peripheral interface and the highest density, radiation and single-event effects performance available in a QML-qualified non-volatile memory for use with space-grade FPGAs and microprocessors,” claimed the company. To puts some numbers on these radiation claims, ...
EPC Space has created two surface-mount 40V radiation-specified GaN hemts for space use. EPC7001BSH is a 50A (120A pulse) 11mΩ transistor in 5.7 x 3.9mm packaging EPC7002ASH is a 15A (40A pulse) 28mΩ transistor in 3.4 x 3.4mm packaging “Both devices have a total dose radiation rating greater than 1,000kRad(Si) and SEE immunity for LET of 83.7MeV/mg/cm2 with Vds up ...
NASA, Texas Instruments and others in the space industry have created a qualification standard for using plastic packaged ICs in space: Qualified Manufacturers List Class P – QML Class P. “QML Class P was designed in league with NASA and other industry experts as a plastic packaging standard for space electronic,” TI told Electronics Weekly. The standard is based on ...
