Host Bridge for PowerPC®
Tested, proven, and in production at leading Communication, Networking and Storage OEMs Applications include routers, base station controllers, SAN Switches, high end laser printers A 133 MHz variant is now generally available Low Latency, High Performance Memory Controller Small Device Footprint
The Tundra Semiconductor Tsi107 PowerPC Host Bridge provides system interconnect between PowerPC processors, PCI peripherals and local memory. PCI support allows system designers to design systems quickly using peripherals already developed for PCI and the other standard interfaces available in the personal computer hardware environment.
The Tsi107 provides many of the other necessities for embedded applications, including a high-performance memory controller and dualprocessor support; two-channel flexible DMA controller; an interrupt controller; an I2O-ready message unit; an inter-integrated circuit controller (I2C); and low-skew clock drivers. The Tsi107 contains an Embedded Programmable Interrupt Controller (EPIC) featuring five hardware interrupts (IRQs), as well as 16 serial interrupts and four timers. The Tsi107 uses an advanced, 2.5V CMOS process technology, and is fully compatible with TTL devices.
