XR19L400 - 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 single 3.3V or 5V power supply.

The L400 is fully compliant with RS-485 Standards.

Key Features

  • Meets true RS-485 standards at 3.3V or 5V operation.
  • Up to 8 Mbps data transmission rate.
  • 45us sleep mode exit (charge pump to full power).
  • ESD protection for RS-485 I/O pins at.
  • +/-15kV - Human Body Model.
  • +/- 8kV - IEC 61000-4-2, Contact Discharge.
  • +/- 15kV - IEC 61000-4-2, Air-Gap Discharge.
  • Software compatible with industry standard 16550 UART.
  • Intel/Motorola bus select.
  • Complete modem interface.
  • Sleep and Power-save modes to conserve b.

XR19L400 SINGLE CHANNEL INTEGRATED UART AND RS-485 TRANSCEIVER APRIL 2018 REV. 1.0.4 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 single 3.3V or 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. In the Partial Sleep mode, the internal crystal oscillator of the UART or charge pump of the RS-485 transceiver is turned off.
