CY7C964

The CY7C964 integrates several space-consuming functions into one small package, freeing board space for the implementation of added-value board features. It contains counters, comparators, latches, and drivers configured to be of value to implementors of any backplane interface with address and data buses, particularly VMEbus interfaces. The on-chip drivers are suitable for driving the VMEbus directly. The CY7C964 is ideal in applications where high-performance and real estate are primary concerns.

Although having many applications, the Bus Interface Logic Circuit is an ideal companion part to Cypress's VMEbus family of components, the VIC068A, VIC64, the CY7C960, and CY7C961. It is intended to drive the address and data buses, so three or four of these small devices are needed per controller. In every case, the controllers provide the control and timing signals to the Bus Interface Logic Circuit as it acts as a bridge between the VMEbus and the Local bus.
