SCC68681C1N40 General Description
The NXP Semiconductors SCC68681C1N40 is a reliable UART chip designed for various embedded systems applications. With its dual independent UART channels, this chip offers efficient asynchronous communication at speeds of up to 1 Mbps. Its versatility is evident in its support for different data formats, including varying word lengths and optional parity and stop bits. The flexible baud rate generator enhances communication precision, while the single power supply voltage and low power consumption make it ideal for energy-efficient designs. Moreover, the hardware flow control mechanisms provided by the SCC68681C1N40 enable seamless data flow management between connected devices
