Whether for desktops, servers, industrial PCs, or embedded systems, the PI7C9X7954BFDE is the ultimate choice for high-speed connectivity and reliable data transmission

主要特徵

  • All three ports compliant with the PCI Local Bus Specification, Revision 2.1
  • Compliant with PCI-to-PCI Bridge Architecture Specification, Revision 1.0
  • 32-Bit Primary and two Secondary Ports
  • Circular-Delta Bus Architecture
  • Concurrent primary to secondary bus operation and independent intra-secondary port channel to reduce traffic on the primary port
  • Provides arbitration for two sets of 8 secondary bus masters
  • ― Programmable 2-level priority arbiters
  • ― Disable control for use of external arbiter
  • Support PCI transactions for:
  • ― All I/O and memory commands
  • ― Type 1 to Type 0 configuration conversion (downstream only)
  • ― Type 1 to Type 1 configuration forwarding
  • ― Type 1 to special cycle configuration conversion
  • Supports posted memory write buffers in all directions
  • Implements delayed transactions for all PCI configuration, I/O and memory read commands
  • Supports positive medium decoding
  • Enhanced address decoding
  • ― 32-Bit I/O address range
  • ― 32-Bit memory-mapped I/O address range
  • ― VGA addressing and VGA palette snooping
  • ― ISA-aware mode for legacy support in the first 64KB of I/O address range
  • IEEE 1149.1 JTAG interface support
  • Full scan support
  • 3.3V core logic with 5V tolerant 3.3V PCI signaling interface
  • 256-pin plastic PBGA package (NA256)
  • Supports system transaction ordering rules
  • Hot-Plug "Ready"
  • Product Benefits
  • Triple port PCI-to-PCI Bridge increases the number of PCI slots that can be supported in a system.
  • Single PI7C7100 device instead of two PCI-to-PCI Bridge devices conserves board real estate and provides one less device load on the primary bus.
  • Concurrent and intra-secondary bus communication increases overall system performance by reducing bus traffic on the primary bus. Devices on secondary busses can independently communicate while the primary bus is busy.
  • Integrated two-level programmable arbiter support for up to 8 devices on each secondary bus maximizes master device control. The internal arbiter can be bypassed with an external arbiter for custom applications.
  • Synchronous clock operation on the primary and secondary busses
  • Enhanced PCI bridge performance and efficiency through support for delayed transactions.
