SERCOMs
SERCOMs, or Serial Communication Controllers, are integrated circuits designed to manage serial data transmission and reception. They act as the interface between a computer's parallel data bus and serial communication lines. This allows devices to communicate with each other over a distance using a minimal number of wires. SERCOMs typically handle protocols like RS-232, RS-485, and UART (Universal Asynchronous Receiver/Transmitter).
The primary function of a SERCOM is to convert data between parallel and serial formats. Internally, a
Modern microcontrollers often include built-in SERCOMs, eliminating the need for external chips in many applications. These
