The VMEbus interface controller (VIC068A) 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 VIC068Aeither a 8-bit, 16-bit, or 32-bit VMEbus system. The VIC068A performs all VMEbus system controller functions plus many others, which simplify the development of VIC068Aa VMEbus interface. The VIC068A 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 VIC068A 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. The VIC068A was developed through the efforts of a consortium of board vendors, under the auspices of the VMEbus International Trade Association (VITA). The VIC068A thus insures compatibility between boards designed by different manufacturers.
