MaxLinear, Inc. UARTs (Universal Asynchronous Receiver Transmitter) XR17D158IV

The XR17D158IV is an octal PCI Bus Universal Asynchronous Receiver and Transmitter (UART) designed for high-performance communication systems. It supports both 3.3V and 5V operation with universal PCI Bus buffers, making it versatile for various applications. The device features a 32-bit PCI Bus interface and is compliant with PCI Bus 2.3 target signaling. Each of the eight UART channels is independently controlled and includes a 16C550 compatible register set, 64-byte transmit and receive FIFOs, and programmable FIFO trigger levels. The device supports automatic hardware flow control (RTS/CTS or DTR/DSR) and software flow control (Xon/Xoff), along with an infrared data encoder/decoder for IrDA applications. Additionally, it includes eight multi-purpose I/O pins and a 16-bit general-purpose timer/counter. The XR17D158IV is suitable for applications such as remote access servers, network management, factory automation, process control, and multi-port RS-232/RS-422/RS-485 cards. Its robust feature set and compatibility with existing designs make it a strong candidate for engineers looking to implement reliable UART communication in their projects.
