General Description

The XR17V2541 (V254) is a single chip 4-channel 66MHz PCI (Peripheral Component Interconnect) UART (Universal Asynchronous Receiver and Transmitter) solution, optimized for higher performance and lower power.

The V254 device with its fifth generation register set is designed to meet the high bandwidth and power management requirements for multi-serial communication ports for system administration and management.

The 32-bit 66MHz PCI interface is compliant with PCI 3.0 and PCI power management revision 1.1 specifications.
