VIC068A-BC

VMEbus Interface Controller
 
 
Features
Complete VMEbus interface controller and arbiter
58 internal registers provide configuration control 
and status of VMEbus and local operations
Drives arbitration, interrupt, address modifier utility, 
strobe, address lines A07 through A01 and data lines 
D07 through D00 directly, and provides signals for 
control logic to drive remaining address and data 
lines
Direct connection to 68xxx family and mappable to 
non-68xxx processors
Complete master/slave capability
Supports read, write, write posting, and block transfers
Accommodates VMEbus timing requirements with 
internal digital delay line (1⁄ 2-clock granularity)
Programmable metastability delay
Programmable data acquisition delays
Provides timeout timers for local bus and VMEbus 
transactions
Interleaved block transfers over VMEbus
Acts as DMA master on local bus
Programmable burst count, transfer length, and interleaved period interval
 Supports local module-based DMA
Arbitration support
Supports single-level, priority and round robin arbitration
Supports fair request option as requester
Interrupt support
Complete support for the VMEbus interrupts: interrupter and interrupt handler
Seven local interrupt lines
8-level interrupt priority encode

Functional Description
The VMEbus interface controller (VIC068A) is a single chip
designed to minimize the cost and board area requirements
and to maximize performance of the VMEbus interface of a
VMEbus master/slave module. This can be implemented on
VIC068A either an 8-bit, 16-bit, or 32-bit VMEbus system. The
VIC068A performs all VMEbus system controller functions
plus many others, which simplify the development of
VIC068Aa VMEbus interface. The VIC068A utilizes patented
on-chip output buffers. These CMOS high-drive buffers provide direct connection to the address and data lines. In addition to these signals, the VIC068A connects directly to the arbitration, interrupt, address modifier, utility and strobe lines.
Signals are provided which control data direction and latch
functions needed for a 32-bit implementation.
The VIC068A was developed through the efforts of a consortium of board vendors, under the auspices of the VMEbus International Trade Association (VITA). The VIC068A thus insures compatibility between boards designed by different
manufacturers.
