Product Summary

The VIC64AC VME bus Interface Controller with D64 functionality is a single chip designed to minimize the cost and board area requirements and to maximize the performance of a VMEbus master/slave module. Data transfers of 70 Mbyte/sec are possible between boards using VIC64AC. In addition to D8, D16, and D32 operations, the VIC64AC performs D64 data transfer. On-chip output buffers are used to provide direct connection to address and data lines. The VIC64AC is based on the industry-standard VIC068A. For most applications, the VIC64AC is fully software and plug compatible with the VIC068A. (As VIC64AC uses register bits that are unassigned in VIC068A, user code may require simple rework to insure compatibility.) The local bus interface of the VIC64-AC emulates Motorola family of 32-bit 68K processor interfaces. Other processors can easily be adapted to interface to the VIC64 using appropriate logic.
