Working Principles

The SP3220EUEY-L/TR is a high-speed RS-232 transceiver that enables bidirectional communication between microcontrollers/microprocessors and serial communication devices. It utilizes a charge pump to convert the logic levels of the UART signals to RS-232 voltage levels (-25V to +25V) and vice versa. The transceiver automatically enters a low-power shutdown mode when not in use, reducing power consumption.
