Functional Description

Cypress’s VIC64 VMEbus Interface Controller with D64 func-

tionality is a single chip designed to minimize the cost and

board area requirements and to maximize the performance of

a VMEbus master/slave module. Data transfers of 70

Mbyte/sec are possible between boards using VIC64.

In addition to D8, D16, and D32 operations, the VIC64 per-

forms D64 data transfer. On-chip output buffers are used to

provide direct connection to address and data lines.

The VIC64 is based on the industry-standard VIC068A. For

most applications, the VIC64 is fully software and plug com-

patible with the VIC068A. (As VIC64 uses register bits that

are unassigned in VIC068A, user code may require simple

rework to insure compatibility.)

The local bus interface of the VIC64 emulates Motorola’s fam-

ily of 32-bit 68K processor interfaces. Other processors can

easily be adapted to interface to the VIC64 using appropriate

logic.

Resetting the VIC64

The VIC64 can be reset by any of three distinct reset condi-

tions:

All three reset options are implemented in a different manner

and have different effect on the VIC64 configuration registers.

VIC64 VMEbus System Controller

The VIC64 is capable of operating as the VMEbus system con-

troller. It provides VMEbus arbitration functions, including:

The system controller functions are enabled by the SCON pin

of the VIC64. This pin is sampled during Reset and if LOW,

VIC64 performs as system controller. After Reset the pin be-

comes an output signifying a D64 transfer.

VIC64 VMEbus Master Cycles

The VIC64 is capable of becoming the VMEbus master in re-

sponse to a request from local resources. In this situation, the

local resource requests a VMEbus transfer. The VIC64 makes

a request for the VMEbus. When the VMEbus is granted to the

VIC64, it then performs the transfer and acknowledges the lo-
