Functional Description
The CY7C960 Slave VMEbus Interface Controller provides the
board designer with an integrated, full-featured VME64 inter-
face. This 64-pin device can be programmed to handle every
transaction defined in the VME64 specification. The CY7C961
is based upon the CY7C960: additional features include Re-
mote Master capability whereby the CY7C961 can be com-
manded to move data as a VMEbus master. The CY7C961 is
packaged in a 100-pin outline.
The CY7C960 contains all the circuitry needed to control large
DRAM arrays and local I/O circuitry without the intervention of
a local CPU. There are no registers to read or write, no com-
plex command blocks to be constructed in memory. The
CY7C960 simply fetches its own configuration parameters
during the power-on reset period. After reset the CY7C960
responds appropriately to VMEbus activity and controls local
circuitry transparently.
