Area-based purposes are an vital space for Infineon Applied sciences AG , with the corporate’s merchandise being utilized in satellites, mars rover devices and house telescopes, all of which require highest reliability even beneath essentially the most antagonistic circumstances. Infineon as we speak introduced availability of the trade’s first radiation-hardened (rad arduous) 1 and a pair of Mb parallel interface ferroelectric- RAM (F-RAM) nonvolatile reminiscence units. These additions to Infineon’s intensive portfolio of reminiscences function unsurpassed reliability and endurance, with as much as 120 years of information retention at 85-degree Celsius, together with random entry and full reminiscence write at bus speeds.
Infineon F-RAM units are intrinsically rad arduous, and the expertise is ideally suited to
the evolving mission necessities of space-based purposes that traditionally have used
slower, much less rugged EEPROM nonvolatile storage units. Options in comparison with alternate options embrace quicker reminiscence random entry, higher information safety with prompt non-volatile write expertise and low energy, with extraordinarily low programming voltage right down to 2 V and most working present of 20 mA.
“As more room purposes are architected to course of information on-system, and never on-ground
through telemetry, there’s growing demand for high-reliability non-volatile reminiscence to work in
tandem with space-grade processors and FPGAs for data-logging purposes,” stated Helmut Puchner, Vice President, Fellow Aerospace and Protection, Infineon Applied sciences. “Infineon launched the primary SPI F-RAM units for this market in 2022, and the addition of parallel interface units displays our dedication to delivering best-in-class, extremely dependable and versatile options for next-generation house necessities.”
Goal purposes for Infineon’s rad arduous F-RAM units embrace information storage for sensors
and devices, information logging for calibration information, safe key storage for information encryption,
and boot code storage. Along with outer house, they’re additionally appropriate for avionic and
different purposes that require navy normal temperature grades (-55°C to 125°C).
Just like the SPI model, the chemical composition of the brand new Infineon parallel interface F-RAM
units leads to distinctive non-volatile reminiscence options, together with instantaneous switching of atomic state, as an alternative of a trapped cost to program bits in EEPROM applied sciences. F-RAM is inherently resistant to tender errors and magnetic discipline or radiation results. There isn’t a requirement for software program to handle web page boundaries, and close to infinite endurance (10 13 write cycles) means there isn’t any want for put on leveling.
The parallel units are packaged in 44-lead ceramic TSOP and the QML-V certified
units have superior radiation efficiency of:
– TID: >150 Krad (Si)
– SEL: >96 MeV·cm 2 /mg @115°C
– SEU: Immune
– SEFI: <1.34 * 10-4 err / dev.day (energetic/standby) / Immune (sleep mode)
