XR28V384 - 3.3V QUAD LPC UART

General Description

The XR28V384 (V384) is a quad Universal Asynchronous Receiver and Transmitter (UART) for the Intel Low Pin Count (LPC) bus interface.

This device can replace or supplement a Super I/O device to add additional serial ports to the system.

Key Features

  • such as the 9-bit (multidrop) mode, IrDA mode and the Watchdog Timer can be enabled. The V384 is available in a 48-pin TQFP package.

4 (V384) is a quad Universal Asynchronous Receiver and Transmitter (UART) for the Intel Low Pin Count (LPC) bus interface. This device can replace or supplement a Super I/O device to add additional serial ports to the system. The V384 UARTs support any 16-bit I/O address supported by the system. The register set is based on the industry standard 16550 UART, so the V384 operates with the standard serial port drivers without requiring a custom driver to be installed. The 128 byte Transmit and Receive FIFOs reduce CPU overhead and minimize the chance of buffer overflow and data loss.
