IC068ABC – Powered To Maximize The Performance Of A Vmebus Interface Controller

VIC068ABC is a VMEbus interface controller, manufactured by Cypress Semiconductor Corporation. The VIC068ABC performs all VMEbus interface controller functions, along with the various other critical operations. The key performance attribute to a VIC068ABC however is to maximize the performance of a VMEbus interface of a VMEbus master/slave module by working upon the cost and board requirements, and deploying patent on-chip output buffers. It is an interface between the local CPU Bus and the VMEbus. VIC068BC is the result of combined effort of a consortium of board vendors, and therefore, is compatible between boards designed by different vendors.

A Perfect Controller, Arbiter, Master/Slave Function Manager

VIC068ABC beyond doubt matches the qualification criteria required for the mentioned designations. The 58 internal registers providing configuration control, explain the controller capabilities. The arbitration support is extended by the single-level, priority and round robin arbitration functionalities. The VIC068 further supports read, write, posting and block transfers to qualify as the master/slave function manager. It also provides for programmable metastability delay and data acquisition delays.

The VIC068ABC further enables interleaved block transfers over the VMEbus. It acts as the DMA master on local bus and supports local module-based DMA. VIC068 provides interrupt support and has 29 interrupts mapped.

VIC068ABC performs the mentioned functions and many others with precision. It is quite easy to manage and can be easily reset by any of the three resetting conditions viz., Internal Reset, System Reset and Global Reset.
