TSI107C-100JE

Specialized Overview

The TSI107C-100JE is a host bridge integrated circuit designed to provide system interconnect between PowerPC processors, PCI peripherals, and local memory. It supports the PowerPC 603e/7xx and MPC74xx processor families with a processor bus frequency of up to 133 MHz. The device features a 64-bit local memory data bus operating at frequencies up to 133 MHz and a 32-bit PCI interface supporting 66 MHz operation. Key embedded components include an Embedded Programmable Interrupt Controller (EPIC), a two-channel DMA controller, and an I2C controller. It also provides an IEEE 1149.1 compliant JTAG boundary-scan interface. The component is available in a 503-ball FCBGA package and operates within a commercial temperature range of 0°C to 105°C junction temperature.

Specialized Feature Summary

• Provides high-performance system interconnect for PowerPC processors and PCI peripherals
• Integrates dual flexible DMA controllers and an embedded programmable interrupt controller
• Supports low-skew clock drivers and I2O-ready message units for embedded applications

Specialized Applications

• System interconnect for PowerPC-based embedded applications
• Interfacing PowerPC processors with PCI peripheral devices
• High-performance memory controller implementations in embedded systems

Specialized Part Context

The TSI107 series serves as a critical host bridge solution for Renesas PowerPC microprocessors. It bridges the local processor bus to the PCI bus, enabling efficient data transfer between the CPU, local memory, and expansion peripherals. This architecture is typical in industrial and communication equipment requiring robust processor-to-peripheral connectivity.

Specialized Replacement Considerations

The TSI107C-100JE is listed as obsolete. Potential replacements within the same family include the TSI107D variants, such as TSI107D-100JE or TSI107D-133LE, though these are also marked as obsolete. Designers should verify pin compatibility and electrical specifications against newer Renesas host bridge solutions if available.
