Teledyne e2v has teamed up with Texas Instruments on a DDR4 memory and power supply design for satellite systems.
The radiation-tolerant platform consists of a 4GB/8GB capacity DDR4T0xG72 DDR4 memory from Teledyne e2v accompanied by a TI TPS7H3301-SP DDR termination low drop-out (LDO) voltage regulator that provides a stable supply for the memory module.
The platform has been designed for the size, weight and power (SWaP) constraints in satellite designs with a third the PCB footprint of other designs an one tenth the volume.
The constituent components have already gone through comprehensive space characterization and qualification procedures to help designers achieve long-term operation without single event latch-up (SEL) and single event upset (SEU) issues arising.
- First space-qualified configurable quad ADC
- Quad core ARM Cortex-A72 processor qualified for space
- AI imaging system for nanosats
The DDR4T0xG72/TPS7H3301-SP modular platform can be used across a wide range of space-grade processors from Teledyne e2v and other suppliers, FPGAs/ACAPs such as AMD/Xilinx, Microchip, and NanoXplore and custom-built ASICs.
“Having access to pre-tested, easy-to-integrate hardware is of real benefit to those constructing systems for space deployment,” said Thomas Guillemain, Marketing Manager for Digital Processing Solutions at Teledyne e2v. “This joint platform results in significant value for our space customers, particularly on SWaP.”
“The DDR4T0xG72/TPS7H3301-SP solution means that space systems will now have access to a small-format module that saves critical board area and offers high power density and verified radiation hardness and reliability,” adds Mark Toth, marketing and applications engineering manager for space-grade power products at TI.
The radiation-validated TI and Teledyne e2v devices that make up this solution are featured in Alpha Data’s Versal Core development kit ADK-VA600.
