PCI9052

The PCI9052 provides a compact high performance PCI Bus Slave interface for adapter boards. The PCI9052 is designed to connect a wide variety of Local Bus designs to the PCI Bus and allow relatively slow Local Bus designs to achieve 132 MB/s Burst transfers on the PCI Bus.

The PCI9052 can be programmed to connect directly to the Non-Multiplexed or Multiplexed mode 8-, 16-, or 32-bit Local Bus. The 8-and 16-bit modes allow easy conversion of ISA designs to PCI. (Refer to Figure 1-1 on page 1-3.)

The PCI9052 contains Read and Write FIFOs to speed match the 32-bit wide, 33 MHz PCI Bus to a Local Bus, which may be narrower or slower. Up to five Local Address spaces and four Chip Select outputs are supported.
