3D PLUS is introducing 3DSD1G48VB2820, a new memory, to broaden its portfolio of space SDRAM.
Since its first release on the market in 2003, 3D PLUS space-qualified SDRAM have been used as processor RAM in a variety of high-performance computer boards, and as high-density storage memory in Solid State Data Recorder boards.
The 3D PLUS space SDRAMs have a distinctive flight heritage as they are used in a variety of space applications including science and deep space missions (e.g: Juno launched in 2011 by NASA), Earth observation (e.g: COSMO-SkyMed satellites with the first one launched in 2007), launchers (e.g: Ariane 5), navigation satellites (e.g: Galileo system). They are also used worldwide in missions such as BepiColombo, a jointly ESA and JAXA mission launched in 2018; EMM, a mission operated by the UAE agency MBRSC, and launched 2020 or Chandrayaan-3, launched in July 2023 by ISRO.
The 3DSD1G48VB2820 SDRAM module features 1.5 Gbit density with 48 bits data bus and 3.3V power supply. It is latch-up immune (SEL > 80 MeV.cm²/mg), and can withstand up to 50 krad (Si) of TID.
The first engineering parts will be available in June 2024 and the qualified flight-grade parts are expected by September 2024.
