Working Principles

The SN65C3232ED is designed to facilitate bidirectional serial communication between microcontroller systems and RS-232 devices. It utilizes a dual-channel architecture, allowing simultaneous transmission and reception of data. The integrated charge pump ensures proper voltage level conversion between the microcontroller's logic levels and the RS-232 standard.

When transmitting data, the microcontroller sends the signal through the TOUT pin, which is then converted to RS-232 levels by the internal circuitry. On the receiving end, the transceiver receives RS-232 signals through the RIN1 and RIN2 pins, converts them to logic levels, and outputs the received data through the ROUT1 and ROUT2 pins.
