... Selectable shutdown for IR and RS-232 circuitry reduces supply current to 1µA. The MAX3130 is optimized for applications using a sin- gle UART for both infrared and RS-232 communication. The infrared transmitter input and infrared receiver out- put are multiplexed with one RS-232 transmitter input and one RS-232 receiver output, respectively. The MAX3131’ ...

For the MAX3130, drive IRMODE low to connect R2OUT to the IR receiver output, and drive IRMODE high to connect R2OUT to the RS-232 receiver output. For the MAX3131, R2OUT is always internally connected to the RS-232 receiver output ...

... The RS-232 transceiver is powered by a high- efficiency, dual charge-pump power supply that oper- ates with input supply voltages from +3.0V to +5.5V. The MAX3130 is optimized for applications using a sin- gle UART for both infrared and RS-232 communication. The infrared transmitter input and infrared receiver out- put are multiplexed with one RS-232 transmitter input and one RS-232 receiver output, respectively ...

... Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies (Figures 1 and 2). If RSSD (or IRMODE for MAX3130) is low, both charge pumps shut down. RS-232 Transmitters The RS-232 transmitters are inverting level translators that convert CMOS-logic levels to ±5.0V EIA/TIA-232 levels ...

... RS-232 and IrDA communication while using only one UART. By using the IRMODE input, the type of communication (infrared or RS-232) is controlled by the I µP. The internal MAX3130 ENDEC is used to translate between UART-type and IrDA-type bit- streams. If the UART has this capability, connect BAUD16 of the MAX3130 to GND ...
