RS232 serial interface — what this transceiver brings to the board
The MAX3225EAP+: Full-duplex RS232 transceiver with 2 drivers and 2 receivers in a 20-SSOP package. Data rate is 1Mbps. The 500 mV receiver hysteresis cleans up noisy RS232 lines common in factory-floor or long-cable runs, reducing false starts on the UART.
