PCI 64-bit Hub

hSa EC6™

The P64H is a peripheral chip that performs PCI bridging functions between the MCH and the PCI 64-bit 66 MHz bus. The P64H has a 16-bit primary hub interface to the MCH and a secondary 64-bit PCI bus interface. This controller inter-operates transparently with either 64-bit or 32-bit devices.

The following figure shows how the P64H chip is connected to the MCH via the Hub Link 16 and to the supported devices such as those in the two PCI 64-bit 66 MHz PCI slots and AIC-7892 Ultra 160 SCSI controller via the PCI

64-bit 66 MHz bus.
