This paper presents the definition of an integrated processor core ASIC named SCOC3 which is designed for space computers. It also presents the validation method that has led to a successful ASIC run at the first time, thanks to Astrium's improved control in microelectronic component design. It is base on the LEON3FT Sparc processor associated to a Floating Point Unit both from Aeroflex Gaisler. The core provides many interfaces to connect various types of electronic units.
