The PI7C9X795x series PCIe UARTs are compliant to PCISIG’s PCIe Gen 1 revision 1.1 specifications and were some of the industry’s first UARTs to offer plug and play configuration. These UARTs can also be operated in synchronous mode to run at a much higher data rate of 62.5 Mbps. The 128-byte transmit and receive FIFOs can handle up to 256-byte payloads. From a software perspective, these UARTs are 16C550 compatible. Additional features such as programmable data frame sizes, clock pre-scalar, and flow control are also supported. All of these UARTs are in lead free and 100% green packages.
