VRC5074

The VRC5074^TM is a single-chip device that provides a glueless interface between a VR5000^TM processor and a DRAM memory system, local I/O bus, and standard PCI bus. The VRC5074 interface controller connects directly to the VRC5074 microprocessor and PCI bus with no buffering required. The DRAM memory interface connecting to local memory contains the logic required to directly drive several types and speeds of SDRAM. The interface control logic VRC5074 is highly configurable by software and can be used with minimal hardware configuration in many different types of systems. The local bus interface connecting to local I/O contains the interface logic necessary to directly drive several types and speeds of peripheral devices.
