Product Summary
The VIC64-AC is a VMEbus interface controller. The VIC64-AC is a single chip designed to minimize the cost and board area requirements and to maximize performance of the VMEbus interface of a VMEbus master/slave module. This can be implemented on VIC068A either an 8-bit, 16-bit, or 32-bit VMEbus system. The VIC64-AC performs all VMEbus system controller functions plus many others, which simplify the development of VIC068Aa VMEbus interface. The VIC64-AC utilizes patented on-chip output buffers. These CMOS high-drive buffers provide direct connection to the address and data lines. In addition to these signals, the VIC64-AC connects directly to the arbitration, interrupt, address modifier, utility and strobe lines. Signals are provided which control data direction and latch functions needed for a 32-bit implementation.
