The PCI2050BIGHK is a high-performance, 32-bit PCI-to-PCI bridge manufactured by Texas Instruments. Designed to extend the PCI bus from a single host (or root) PCI bus to multiple device PCI buses, this component is ideal for systems requiring expansion of the PCI bus to accommodate additional peripherals and devices. The PCI2050BIGHK is compliant with the PCI Local Bus Specification, Revision 2.2, ensuring compatibility with existing and future PCI devices.

Key Features

• 32-bit, 33-MHz PCI-to-PCI bridge in compliance with PCI Local Bus Specification 2.2
• Supports up to 5 secondary PCI buses for extensive system expansion
• Low-profile, 208-Pin Thin Quad Flat Pack (TQFP) package suitable for compact designs
• 3.3V operation with 5V tolerant inputs for mixed-voltage environments
• Secondary bus reset control for easy management and initialization of connected devices
• Configurable as a positive decode or subtractive decode bridge
• Integrated arbitration and bus mastering support for efficient data transfer
• Support for delayed transactions and PCI bus parking for enhanced performance
• Hot-swap and hot-plug capabilities for easy maintenance and upgrades

Applications

The PCI2050BIGHK is versatile and can be used in a wide range of applications. It is particularly useful in systems that require additional PCI slots, such as:

• Industrial control systems
