Infineon Extends Radiation-Hardened Reminiscence Portfolio With Business’s First House Certified Parallel Interface 1 & 2 Mb F-RAMs

House-based functions are an vital space for Infineon Applied sciences AG , with the corporate’s merchandise being utilized in satellites, mars rover devices and area telescopes, all of which require highest reliability even underneath essentially the most antagonistic situations. Infineon immediately introduced availability of the business’s first radiation-hardened (rad arduous) 1 and a couple of Mb parallel interface ferroelectric- RAM (F-RAM) nonvolatile reminiscence units. These additions to Infineon’s in depth portfolio of recollections characteristic 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 know-how is ideally fitted to
the evolving mission necessities of space-based functions that traditionally have used
slower, much less rugged EEPROM nonvolatile storage units. Options in comparison with options embody quicker reminiscence random entry, higher knowledge safety with immediate non-volatile write know-how and low energy, with extraordinarily low programming voltage all the way down to 2 V and most working present of 20 mA.

“As more room functions are architected to course of knowledge on-system, and never on-ground
by way of telemetry, there’s rising demand for high-reliability non-volatile reminiscence to work in
tandem with space-grade processors and FPGAs for data-logging functions,” mentioned 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 area necessities.”

Goal functions for Infineon’s rad arduous F-RAM units embody knowledge storage for sensors
and devices, knowledge logging for calibration knowledge, safe key storage for knowledge encryption,
and boot code storage. Along with outer area, they’re additionally appropriate for avionic and
different functions 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 ends in distinctive non-volatile reminiscence options, together with instantaneous switching of atomic state, as a substitute of a trapped cost to program bits in EEPROM applied sciences. F-RAM is inherently resistant to delicate errors and magnetic area or radiation results. There isn’t any requirement for software program to handle web page boundaries, and close to infinite endurance (10 13 write cycles) means there isn’t a 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 (lively/standby) / Immune (sleep mode)
