NEC testing highly radiation-hardened semiconductor chip in space:
Tokyo, January 18, 2019 – NEC has developed a highly radiation-hardened (radiation-resistant) semiconductor chip, the “NanoBridge-FPGA (NB-FPGA)*1,”
it aims to demonstrate the operational reliability of the chip in space.
This chip was developed utilizing results from a project*2 coordinated by the New Energy and Industrial Technology Development Organization (NEDO).
On January 18, 2019, Japan Aerospace Exploration Agency (JAXA) launched the “RAPid Innovative payload demonstration Satelite-1 (RAPIS-1),”
equipped with NEC’s newly developed NB-FPGA, on the fourth Epsilon Launch Vehicle (Epsilon-4) under JAXA’s innovative satellite technology demonstration program.
JAXA and NEC are now starting joint collection and evaluation of basic data on the NB-FPGA, including error rate measurement, in a space environment where radiation is very high.
In addition, the reliable operation of image data compression is also being verified.
