PRELIMINARY

SINGLE CHANNEL INTEGRATED UART AND RS-232 TRANSCEIVER

XR19L200

APRIL 2006

REV. P1.0.2

APPLICATIONS

GENERAL DESCRIPTION

• Battery-Powered Equipment

• Handheld and Mobile Devices

• Handheld Terminals

• Industrial Peripheral Interfaces

• Point-of-Sale (POS) Systems

The XR19L200 (L200) is a highly integrated device that

combines

a single channel Universal Asynchronous

Receiver and Transmitter (UART) and an RS-232

transceiver. The L200 is designed to operate with a single

3.3V or 5V power supply. The L200 is fully compliant with

EIA/TIA-232-F Standards from a +3.0V to +5.5V power

supply. The device operates at 250 Kbps data rate with

worst case 3K ohms load. Both RS-232 driver outputs and

receiver inputs can operate in harsh electrical environments

of +/-15V without damage and can survive multiple +/-15kV

ESD on the RS-232 lines, while maintaining RS-232 output

levels.

FEATURES

• Meets true EIA/TIA-232-F Standards from a 3.0 V to 5.5V

operation

• Up to 250 Kbps data transmission rate

The L200 operates in three different modes: Awake, Partial

Sleep, and Full Sleep. Each mode can be invoked via

hardware or software. In the Awake mode, all functions are

active. In the Partial Sleep mode, the internal crystal

oscillator or charge pump is turned off. In Full Sleep mode,

the internal crystal oscillator and the charge pump is shut

down. All the RS-232 receivers remain active in any of

these four modes.

• 45us sleep mode exit (charge pump to full power)

• ESD protection for RS-232 I/O pins at

■ +/-15kV - Human Body Model

■ +/-15kV - IEC 1000-4-2, Air-Gap Discharge

■ +/- 8kV - IEC 1000-4-2, Contact Discharge

• Software compatible with industry standard 16550 UART

• Intel/Motorola bus select

• Quarter-modem interface (TXD, RXD)

• Sleep modes to conserve battery power

• Wake-up interrupt upon exiting low power modes
