Description



The XR19L210 (L210) is a highly integrated device that combines a full-featured single channel Universal Asynchronous Receiver and Transmitter (UART) and an RS-232 transceiver. The L210 is designed to operate with a single 3.3V or 5V power supply. The L210 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.

The L210 operates in four different modes: Awake, Partial Sleep, Full Sleep and Power-Save. Each mode can be invoked via hardware or software.

The L210 operates in four different modes: Awake, Partial Sleep, Full Sleep and Power-Save. Each mode can be invoked via hardware and/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. In the Power-Save mode, the core logic is isolated from the control signals (chip select, read/write strobes, address and data bus lines). All the RS-232 receivers remain active in any of these four modes
