TSI108-200CL

Specialized Overview

The TSI108-200CL is a PowerPC host bridge supporting MPC74xx and PPC750 processors at up to 200 MHz. It features a PCI-X interface operating up to 133 MHz, compliant with PCI 2.3 and PCI-X 1.0 standards. The integrated memory controller supports DDR2-400 SDRAM devices running at 200 MHz. Key specifications include two independent Gigabit Ethernet ports, four DMA/XOR channels, and an HLP interface for Flash access. The device utilizes a 1023-pin FCBGA package (33x33 mm) with typical power consumption of 2.5W and maximum of 3.7W.

Specialized Feature Summary

• Integrated bus arbiters for processor and PCI/X devices
• Supports CompactPCI Hot Swap functionality
• JTAG boundary scan support with register access capability
• Clock generator with spread-spectrum capabilities

Specialized Applications

• Printer Controller Boards
• Processor PMC (PrPMC) embedded applications
• Wireless infrastructure systems
• Storage networking equipment

Specialized Procurement Notes

Verify component authenticity through authorized Renesas or IDT distributors due to end-of-life status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Validate package integrity upon receipt, as the 1023-pin FCBGA requires careful handling. Ensure all technical datasheets are current before integration into final designs.

Specialized Selection Notes

Select this component when interfacing PowerPC MPC74xx or PPC750 processors with PCI-X peripherals. Verify system requirements align with the 200 MHz processor and 133 MHz PCI-X operational limits. Consider the integrated DDR2-400 controller if memory latency reduction is required. Evaluate power constraints against the 2.5W typical consumption rating.

Specialized Part Context

Part of the Tundra Tsi108 series designed for high-performance PowerPC interconnect solutions. Originally developed by Integrated Device Technology (IDT), now under Renesas Electronics. Designed to reduce system complexity by integrating multiple interfaces including Ethernet, memory, and PCI-X into a single chip architecture.

Specialized Replacement Considerations

TSI109-200CL serves as a functional replacement within the same product family. Both components share similar architectural goals but differ in specific interface configurations. Verify pin compatibility and software register mappings before substitution.
