The SCC2681AC1A44,518 is a versatile integrated circuit from NXP Semiconductors designed to serve as a dual Universal Asynchronous Receiver/Transmitter (UART) interface. This component is specifically engineered to facilitate serial communication in microprocessor systems by converting bytes from the system’s bus to serial bits for transmission, and vice versa.
Key Features
- Dual-Channel Operation: The device contains two independent UART channels, allowing for simultaneous transmission and reception of serial data on two separate lines.
- Baud Rate Generation: Each UART channel is capable of generating its own baud rate, which can be programmed independently to a wide range of frequencies for flexible communication options.
- Programmable Parameters: Users can set various communication parameters such as character length, parity, stop bits, and baud rate to match specific communication protocols.
- Modem Control Functions: The SCC2681AC1A44,518 includes a complete set of modem control functions, making it suitable for modem interface applications.
- On-Chip Status Registers: Status registers provide detailed information on the state of each UART channel, including error conditions and line status.
- Interrupt Capability: The device supports interrupt-driven operation, which minimizes CPU overhead by alerting the system only when attention is needed.
