Essential details：PT-VME330B REV:B Performance 16 Port High Density/Low CostVME Communications Controller
Performance Technologies’ VME330BIntelligent Communications Controllerfor the VMEbus is our newest WANproduct, offering a very cost effectivehigh density serial communicationsinterface. A fourth generation productit builds on PTI’s ten years experienceand expertise providing communica-tions solutions for the WAN market.
Designed as a fully programmablecommunications sub-system, it iscapable of sustaining the high speeddata rates used with a variety of proto-cols in synchronous and asynchro-nous data communications.
Unlike other controllers, the onboardintelligence and large DRAM array ofthe PT-VME330B allow it to handlemost of the low level communicationsactivities that would typically burdenthe host. This can greatly enhanceoverall system performance. TheDRAM also allows the downloading ofprotocols for stand-alone code execu-tion directly on the PTVME330B.
Operating under real-world protocoloverheads, it can sustain concurrentthroughput of over 137 Kbps full-duplex on each of its 16 channels andover 1.8 Mbits/sec using a singlechannel.

PT-VME330B REV:B Performance 16 Port High Density/Low CostVME Communications Controller
The PT-VME330B capitalizes on theintelligence of the Motorola 68ECO30and up to eight dual channel 85230synchronous comm controllers(SCCs). These are coupled to PTI’sproprietary 32-channel DMA controllerin a highly optimized fashion to ensurehigh-speed data movement betweenthe SCCs and the DRAM data buffer.
The high bandwidth local memory ofthe PT-VME330B provides the deterministic element necessary to allowboth SIO Xmit and Receive operationsto continue on all ports without loss ofdata, even during sustained and prolonged VMEbus accesses.
The VME330B also features PTI’s VS(VME Slave Interface) ASIC whichincorporates a number of uniqueadvantages while providing a high performance interface in full compliancewith the VMEbus Specification C.1.
The PT-VME330B includes support foraddressing 4 GBytes of memory and32 bit data transfers. The VMEbusinterface also supports Block ModeBLT) operation. This is especiallyeffective for moving large contiguousblocks of information while minimizingbus control overhead.
