PCI2040GGU

PCI2040GGU Description

The PCI2040GGU from Texas Instruments is a PCI-to-DSP bridge controller designed to facilitate high-speed communication between PCI-based host systems and digital signal processors (DSPs). Packaged in a 144-BGA form factor, this IC operates within a 0°C to 70°C temperature range and supports dual-voltage supply (3.3V or 5V), making it versatile for embedded systems. Though now obsolete, it remains relevant in legacy designs due to its robust PCI interface and REACH/RoHS3 compliance, ensuring environmental and regulatory adherence.

PCI2040GGU Features

• PCI Interface: Enables seamless integration with PCI host systems for high-bandwidth data transfer.
• Dual-Supply Voltage (3.3V/5V): Offers flexibility in power design for mixed-voltage environments.
• Moisture Sensitivity Level (MSL 3): Suitable for industrial applications with moderate exposure risk.
• RoHS3 Compliant: Meets stringent environmental standards for hazardous substance restrictions.
• Compact 144-BGA Package: Optimizes board space while ensuring reliable thermal performance.

PCI2040GGU Applications

This bridge controller is ideal for:

• Legacy DSP Systems: Bridging PCI hosts to DSPs in audio/video processing, telecommunications, and industrial control.
• Embedded Computing: Facilitating communication in PCI-based embedded platforms requiring DSP co-processing.
• Test & Measurement Equipment: Enabling high-speed data acquisition and signal analysis.

Conclusion of PCI2040GGU

The PCI2040GGU provides a reliable, though now obsolete, solution for PCI-DSP interfacing, combining flexible power options, compact packaging, and compliance with environmental standards. Its niche in legacy DSP systems and embedded applications ensures continued utility in specialized industrial and communication designs. Engineers seeking backward-compatible PCI-DSP bridging may still find value in this controller for maintenance or phased-upgrade scenarios.
