Product Summary

Cypress’s VIC64-AC VMEbus 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 VIC64-AC. In addition to D8, D16, and D32 operations, the VIC64-AC performs D64 data transfer. On-chip output buffers are used to provide direct connection to address and data lines. The VIC64-AC is based on the industry-standard VIC068A. For most applications, the VIC64-AC is fully software and plug compatible with the VIC068A. (As VIC64-AC 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’s family of 32-bit 68K processor interfaces. Other processors can easily be adapted to interface to the VIC64 using appropriate logic.
