Tundra Semiconductor Corp.'s Tsi109 host bridge for PowerPC processors that supports PCI-X, DDR2-400 SDRAM, Gigabit Ethernet, and Flash is in full production.

The Tsi109 host bridge is capable of dual processor support at 167MHz. In addition to 2.5W typical power dissipation, the Tsi109 supports DDR2 memory, which makes suitable for high-density, power-sensitive applications. It is designed with an advanced dynamic memory pipeline architecture, which is said to minimize critical memory access time and maximize bandwidth.

The Tsi109 host bridge integrates a clock generator with spread-spectrum capabilities, a DDR2-400 memory controller, and internal processor and PCI/X bus arbiters. The designer can select from PCI/PCI-X modes and configure it as a PCI Host/Agent. A JTAG interface also simplifies the debug process by allowing access to Tsi109's registers without impacting active transactions.

The Tsi109 is available in both standard and lead-free packages for commercial and industrial temperatures. Volume pricing for the Tsi109 is less than $75.

For documentation, including ordering information, user manuals, and software drivers, to assist in accelerated development with the Tsi109, go to the company's website.
