TSI107D-133LE

Specialized Overview

The TSI107D-133LE is a host bridge integrated circuit manufactured by Renesas Electronics Corporation, designed to provide system interconnect between PowerPC processors and peripheral components. It supports processor bus frequencies up to 133 MHz and features a 64-bit local memory data bus operating at the same speed. The device includes a 32-bit PCI interface supporting 66 MHz operation and an embedded programmable interrupt controller (EPIC). Key internal peripherals consist of a two-channel flexible DMA controller, an I2C controller, and IEEE 1149.1 compliant JTAG boundary-scan capabilities. It is available in a 503-ball FCBGA package.

Specialized Feature Summary

• Provides high-performance system interconnect for PowerPC 603e/7xx and MPC74xx processors
• Integrates dual-channel flexible DMA controllers for efficient data movement
• Supports low-skew clock drivers and embedded interrupt management
• Includes on-chip I2C controller and standard JTAG boundary-scan interface

Specialized Applications

• Embedded systems requiring PowerPC processor connectivity
• Industrial control applications utilizing PCI peripheral expansion
• Network infrastructure equipment needing robust host bridging

Specialized Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review latest product change notifications for any labeling or material updates issued by the manufacturer before finalizing procurement plans.

Specialized Selection Notes

Select this component when interfacing PowerPC architectures with PCI buses is required. Ensure design compatibility with 133 MHz processor and memory bus speeds. Verify that the 503-ball FCBGA footprint fits the target PCB layout constraints and thermal requirements.

Specialized Part Context

This part belongs to the TSI107 series of host bridges developed for embedded PowerPC applications. It serves as a critical link between the processor core and system peripherals, offering integrated memory control and interrupt management to reduce external component count in complex embedded designs.

Specialized Replacement Considerations

The TSI108 is documented as a successor host bridge product within the same family. Evaluate pinout compatibility and feature parity when considering migration from the TSI107D-133LE to newer generations.
