File:PCI pads - as seen on COK-002
note: Two circular pads in the bottom right corner are for southbridge serial

PCI

Bus, resembling Conventional PCI 2.3, directly connected to South Bridge, with 80 exposed pads

Major differences from PCI standard:

  • smaller formfactor (80 pin, instead of miniPCI 100P-type I/II or MiniPCI 124P-Type III)
  • no use of miniPCI standard sideband signals for audio and communications
  • no support of the miniPCI standard CLKRUN# signal defined in the PCI Mobile Design Guide
  • no support for optional JTAG signals, nor for the 64-bit PCI extension defined in the PCI Local Bus Specification

South Bridge serial
