Optimized for Low Earth Orbit constellations, Infineon’s new reminiscence and energy merchandise help dependable, compact, and cost-effective satellite tv for pc operations.
Infineon Applied sciences has launched a brand new vary of radiation-tolerant reminiscence gadgets designed particularly for Low Earth Orbit (LEO) satellite tv for pc functions, marking its entry into the fast-evolving NewSpace phase. As hundreds of LEO satellites proceed to be deployed for functions like international connectivity, distant sensing, and direct-to-device communication, there’s a rising demand for compact, cost-efficient, and dependable onboard electronics.
Not like conventional satellites in geostationary orbit (GEO), LEO satellites function in a decrease radiation surroundings and sometimes have shorter mission lifespans. This enables for using extra commercially viable digital elements with out compromising on reliability. Infineon’s new reminiscence portfolio addresses these wants with elements tailor-made for small satellites—starting from nanosats to 250 kg class satellites—enabling scalable and economical deployment of LEO constellations.
The brand new reminiscence household contains:
- Low-power, radiation-tolerant F-RAMs
- Excessive-density QSPI NOR Flash (256 Mbit and 512 Mbit)
- 256 Mbit and 512 Mbit pseudo-static RAM (pSRAM)
These gadgets are optimized for area missions with constraints on dimension, weight, energy, and price (SWaP-c). The F-RAMs are rated for -55°C to +125°C and provide a radiation tolerance of fifty krad(Si). NOR Flash and pSRAMs help -40°C to +125°C, with radiation rankings of 30 krad(Si) and 100 krad(Si), respectively. Every system undergoes full electrical testing and provides single lot date code traceability.
A spotlight of the portfolio is the pSRAM, a novel hybrid that behaves like static RAM externally whereas functioning like DRAM internally, providing a power-efficient, high-throughput resolution excellent for information buffering in area programs.
Complementing this reminiscence lineup is a collection of radiation-tolerant energy gadgets from Infineon’s IR HiRel group. These embody 60 V and 150 V N- and P-channel energy MOSFETs, rated to 30 krad(Si) and certified to AEC-Q101 requirements—designed to face up to the calls for of 2-to-5-year LEO missions.
