www.DataSheet4U.com APRIL 2007 PRELIMINARY XR19L400 REV. P1.0.0 SINGLE CHANNEL INTEGRATED UART AND RS-485 TRANSCEIVER GENERAL DESCRIPTION The XR19L400 (L400) is a highly integrated device that combines a full-featured single channel Universal Asynchronous Receiver and Transmitter (UART) and RS485 transceivers. The L400 is designed to operate with a 3.3V to 5V power supply. The L400 is fully compliant with RS-485 Standards. The L400 operates in four different modes: Active, Partial Sleep, Full Sleep and Power-Save. Each mode can be invoked via hardware or software. Upon power-up, the L400 is in the Active mode where the UART and RS-485 transceiver function normally.
