Connect Tech ADG043 - PCI-104 to PC/104 Adapter

Allows Usage of PC/104 (ISA) Devices in a PCI-104 (PCI) Only System


Connect Tech’s PCI-104 to PC/104 Adapter allows for the testing and development of PC/104 (ISA) devices in a PCI-104 (PCI) only system. The PCI-104 to PC/104 Adapter converts transactions on the PCI-104 bus to PC/104 bus transactions (PCI to ISA).

PCI-104 to PC/104 Adapter Features

  • 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)
  • Lifetime warranty and free technical support



FeaturesPC/104 IO Space
• Separate PCI IO registers covering 3 fully customizable 256byte IO address ranges

PC/104 Memory space
• PCI Memory mapped BAR covering the entire ISA memory mapped address range (0x00 0000-0xFF FFFF)

Eeprom interface
• On board eeprom loads customizable configuration parameters at boot time

• PCI driven interrupt architecture monitors enabled IRQ input lines on the PC/104 bus.

Digital I/O
• 16-bit bidirectional I/O (optional)
• Input/Output Ranges: Hardware selectable +3.3V or +5V(TTL/CMOS)
• High Current: 24mA
