Table 1: OXCB950 performance compared with PLX + generic UART combinations in PCI mode
1.1
Improvements of the OXCB950 over discrete solutions:
Improved access timing:
Access to the internal UART requires zero or one PCI wait states. A cardbus/PCI read transaction fromthe internal UART can
complete within five PCI clock cycles and a write transaction to the internal UART can complete within four PCI clock cycles.
Reduces interrupt latency:
The OXCB950 offers shadowed FIFO levels and Interrupt status registers of the internal UART, as well as general device
interrupt status, to reduce the device driver interrupt latency.
Power management:
The OXCB950 complies with the Cardbus Power Management Specification, given by the PC CARD standard release 7.0/7.1,
the PCI Power Management Specification 1.0 and the PC98/99 Power Management specifications, by offering the extended
capabilities for Power Management and supporting the power states D0, D2 and D3. This achieves significant power savings by
allowing device drivers to power down the cardbus/PCI function and disable the UART channel.
