Teledyne e2v has made available its engineering models for the new 16GB radiation-tolerant DDR4 memory. This high-density addition expands Teledyne e2v’s space-grade DDR4 portfolio with hundreds of 4GB and 8GB flight models delivered to date.
The 16GB DDR4 device maintains the compact form factor of the existing family — just 15mm x 20mm x 1.92mm — and is pin-to-pin compatible with the 4GB and 8GB variants. This compatibility ensures a smooth upgrade path, allowing system designers to scale memory capacity without a complete board redesign.
Fully compatible with all major space-grade processors and FPGAs, including Teledyne e2v’s own LS1046-Space, LX2160-Space, and QLS1046-Space, the memory operates at speeds up to 2400MT/s. It is engineered for robustness in harsh space environments, with a Total Ionizing Dose (TID) tolerance of 100 krad (Si), Single Event Latch-up (SEL) immunity above 60 MeV.cm²/mg, and advanced SEU/SEFI mitigation for reliable, no-data-loss recovery.
“As satellite payloads grow increasingly complex, the demand for higher memory densities becomes critical,” said Thomas Guillemain, Marketing & Business Development, Digital Processing Solutions at Teledyne e2v. “With the release of our 16GB DDR4 engineering models, system architects can begin early validation with confidence, preparing for a seamless transition to flight-qualified versions.”
Engineering models of the 16GB DDR4 are available now, enabling early-stage development and system validation ahead of full flight deployment.
