Functional Description

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.

Features

• Comparators, counters, latches, and drivers minimize logic requirements for a variety of multiplexed and non-multiplexed buses

• Directly drives VMEbus address and data signals

• 8-bit comparator for slave address decoding

• Flexible interface optimized for VMEbus applications

• Companion device to Cypress VMEbus family of components

• Replaces multiple SSI/MSI components

• Cascadable

• 64-pin QFP and 68-pin PGA packages

• See the VMEbus Interface Handbook for more information
