R400 DATA
INTEL® SYSTEM CONTROLLER
PRODUCT OVERVIEW RadiSys R400EX High-Integration Intel486 System Controller member RadiSys family long-life embedded core logic. Designed specifically support Intel486 processors, R400EX true third-generation embedded chip that addresses functional needs embedded
functional design R400EX based architecture. DRAM controller compatible with both Fast-Page-Mode (FPM) Extended-Data-Out (EDO) DRAM. keyboard/mouse controller real-time clock PC-compatible. enhanced interface supports maximum transfer rate 7.33MB second. ISAbus controller separate data bus, manages signals ensure quiet cycles directed address space.
