Product Summary

The GD82551IT is an evolutionary addition controller. It provides excellent performance by offloading TCP, UDP and IP checksums and supports TCP segmentation off-load for operations such as Large Send. The GD82551IT provides an extended operating temperature in addition to all of the same capabilities and features as the GD82551IT to address applications requiring a wider operating temperature range. Its optimized 32-bit interface and efficient scatter-gather bus mastering capabilities enable the 82551IT to perform high speed data transfers over the PCI bus. This capability accelerates the processing of high level commands and operations, which lowers CPU utilization. Its architecture enables data to flow efficiently from the bus interface unit to the 3 KB Transmit and Receive FIFOs, providing the perfect balance between the wire and system bus. In addition, multiple priority queues of the GD82551IT are provided to prevent data underruns and overruns.
