OX12PCI840 Datasheet | Oxford Semiconductor

FEATURE - - - IEEE1284 SPP/EPP/ECP parallel port Single function target PCI controller, fully PCI 2.2 and PCI Power Management 1.0 pliant 2 multi-purpose IO pins which can be configured as interrupt input pins - - - OX12PCI840 Integrated Parallel Port and PCI interface Can be reconfigured using optional non-volatile configuration memory (EEPROM) 5.0V operation 100 pin PQFP package DESCRIPTION The OX12PCI840 is a single chip solution for PCI-based parallel expansion add-in cards. It is a single function PCI device. For legacy applications the PCI resources are arranged so that the parallel port can be located at standard I/O addresses. The efficient 32-bit, 33MHz target- only PCI interface is pliant with version 2.2 of the PCI Bus Specification and version 1.0 of PCI Power Management Specification. For full flexibility, all the default register values can be overwritten using an optional Microwire TM serial EEPROM. The OX12PCI840 provides an IEEE1284 EPP/ECP parallel port which fully supports the existing Centronics interface.
