Working Principles

The MCP2120T-I/SL operates based on the principles of UART communication. It uses a start bit, data bits, optional parity bit, and stop bit(s) to transmit data between devices. The UART interface converts parallel data into serial format for transmission and vice versa.

When transmitting data, the IC sends a start bit followed by the data bits, optionally including a parity bit for error detection. The receiving device detects the start bit, synchronizes with the transmission, and reads the data bits. It can also verify the parity bit to ensure data integrity.
