XR16M680 1.62V TO 3.63V HIGH PERFORMANCE UART WITH 32-BYTE FIFO SEPTEMBER 2008 REV. 1.0.0 GENERAL DESCRIPTION The XR16M6801 (M680) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with 32 bytes of transmit and receive FIFOs, selectable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 16 Mbps at 3.3V, 12.5 Mbps at 2.5V and 7.5 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.
