datasheetFeatures
The PCI2050B bridge supports the following features:
• Two 32-bit, 66-MHz PCI buses
• 3.3-V core logic with universal PCI interfaces compatible with 3.3-V and 5-V PCI signaling environments
• Internal two-tier arbitration for up to nine secondary bus masters and supports an external secondary bus
arbiter
• Ten secondary PCI clock outputs
• Independent read and write buffers for each direction
• Burst data transfers with pipeline architecture to maximize data throughput in both directions
• Supports write combing for enhanced data throughput
• Up to three delayed transactions in both directions
• Supports the frame-to-frame delay of only four PCI clocks from one bus to another
• Bus locking propagation
• Predictable latency per PCI Local Bus Specification
• Architecture configurable for PCI Bus Power Management Interface Specification
• CompactPCI hot-swap functionality
• Secondary bus is driven low during reset
• VGA/palette memory and I/O decoding options
• Advanced submicron, low-power CMOS technology
• 208-terminal PDV, 208-terminal PPM, or 257-terminal MicroStar BGA™ package
