TSI382A-66CQY

Specialized Overview

The TSI382A-66CQY is a high-performance bridge device that converts single-lane PCI Express signals to a 32-bit PCI interface. It supports PCI clock frequencies up to 66 MHz and offers three addressing modes: transparent, opaque, and non-transparent. The component operates within a temperature range of -40°C to +85°C and utilizes dual power supplies of 1.2 V and 3.3 V. It is housed in a 144-pin CABGA package with dimensions of 10x10 mm.

Specialized Feature Summary

• Provides a compact bridge solution from single-lane PCI Express to 32-bit PCI
• Supports flexible addressing through transparent, opaque, and non-transparent modes
• Includes dedicated clock and arbitration pins for connecting up to four PCI devices

Specialized Applications

• High-performance embedded systems requiring PCIe to PCI connectivity
• Industrial equipment needing low-latency data transfer between bus architectures
• Systems utilizing multiple legacy PCI peripherals with modern PCIe hosts

Specialized Procurement Notes

Verify the specific suffix CQY against official Renesas documentation to confirm package type and temperature grade. Confirm current availability status as distribution channels may list this part as obsolete or limited supply. Ensure compatibility with existing system power requirements for 1.2V and 3.3V rails before integration.

Specialized Selection Notes

Select this component when a small form factor bridge is required for single-lane PCIe to 32-bit PCI conversion. Consider the 10x10mm BGA package constraints during PCB layout. Verify that the target application requires support for non-transparent bridging or specific arbitration features provided by the clock and arbitration pins.

Specialized Part Context

This model belongs to the TSI382 series of PCI Express to PCI bridges manufactured by Renesas Electronics. The series is designed to provide superior performance and low latency for systems transitioning from legacy PCI buses to modern PCI Express architectures while maintaining compatibility with standard 32-bit PCI protocols.
