XR16M581 1.62V TO 3.63V UART WITH 16-BYTE FIFO AND VLIO INTERFACE www.DataSheet4U.com FEBRUARY 2009 REV. 1.0.0 GENERAL DESCRIPTION The XR16M5811 (M581) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with a VLIO bus interface and has 16 bytes of transmit and receive FIFOs, programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 20 Mbps at 3.3V, 16 Mbps at 2.5V and 10 Mbps at 1.8V with 4X data sampling rate. The Auto RS-485 Half-Duplex Direction control feature simplifies both the hardware and software for half-duplex RS-485 applications. In addition, the Multidrop mode with Auto Address detection increases the performance by simplifying the software routines.
