PCI-104 to PC/104 Adapter

  • Converts transactions on the PCI-104 bus to PC/104 bus transactions (PCI to ISA)
  • Acts as a PCI target on the PCI-104 host system, and as the ISA host on the PC/104 bus
  • Maps PCI address space to ISA address space through base address registers
  • Fully customizable IO and memory address ranges, loaded at system start-up via on-board EEPROM interface
  • Supports 8 and 16-bit memory and I/O data transfers on the ISA bus
  • Automatically performs multiple ISA bus operations for each PCI 32bit transfer
  • PCI driven interrupt controller monitors and relays triggered IRQ lines on the PC/104 bus
  • Additional 16 bi-directional Digital I/O accessible over the PCI bus (optional)
