1 Product Description
The TCP872 is a standard 3U CompactPCI module with an interface for up to two 16 bit PC Card or
32 bit CardBus Cards using a dual socket PC Card controller and a power management unit. Up to
two PC Card / CardBus Cards of Type I and II, or one card of Type III are supported. The register map
of the PC Card controller is Intel 82365-DF compatible.
The TCP872 provides full ExCA register implementation for 16 bit PC Cards compatible with PCMCIA
2.1/JEIDA 4.2 standards. Both memory and I/O cards are supported. Up to five memory windows and
up to two I/O windows are available for PC Card16 accesses. For 32 bit CardBus cards two memory
windows and two I/O windows are supported by the controller. CardBus card status information can be
accessed in five card bus socket registers which can be mapped in the host memory space.
The TCP872 can operate with 3.3V and 5.0V PCI I/O signaling voltage.
All CardBus / PC Card interrupt sources are mapped to PCI INTA.
The power management unit provides 3.3V or 5.0V PC Card power supply and 3.3V, 5.0V or 12V PC
Card programming voltage. Due to the short circuit and thermal protection of the power management
unit no external fuses are needed on the module.
The operating temperature range is -40°C to +85°C.
The TCP872 complies with the PICMG 2.0 Revision 3.0 CompactPCI specification.
