Teledyne e2v and TI collaborate on rad-tolerant DDR4 module
Satellite OEMs can streamline system development work with less time and engineering effort involved by using the latest radiation-tolerant DDR4 modular platform, said Teledyne e2v and Texas Instruments (TI). The two companies collaborated on the hardware which consists of a 4Gbyte / 8Gbyte capacity DDR4T0xG72 DDR4 memory from Teledyne e2v and a TI TPS7H3301-SP DDR termination low drop-out (LDO) voltage regulator that provides a stable supply for the DDR4 module.
The DDR4/TPS7H3301-SP is optimised for implementations where there are acute size, weight and power (SWaP) constraints. The DDR4 memory and LDO voltage regulator have already gone through space characterisation and qualification procedures to help designers achieve long-term operation without single event latch-up (SEL) and single event upset (SEU) issues arising, confirmed Teledyne e2v.
The modular platform allows elevated levels of data storage capacity to be achieved within a very small form factor. It requires three times less PCB area compared to competing solutions available today, said the company. It is also smaller in volume by a factor of 10.
The DDR4T0xG72/TPS7H3301-SP 7is applicable across a wide range of space-grade processors (including Teledyne e2v), FPGAs/ACAPs (such as AMD/Xilinx, Microchip, NanoXplore) and custom-built ASICs.
Thomas Guillemain, marketing manager for digital processing solutions at Teledyne e2v, commented: “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,” added Mark Toth, marketing and applications engineering manager for space-grade power products at TI.
The radiation-validated TI and Teledyne e2v devices are featured in Alpha Data’s Versal Core development kit ADK-VA600.
Teledyne e2v has a portfolio of products for customers in the healthcare, life sciences, space, transportation, defence and security and industrial markets.
