NXP SC16C654BIA68,518 Quad UART Interface

The NXP SC16C654BIA68,518 is a highly integrated quad Universal Asynchronous Receiver/Transmitter (UART) interface device that is designed to provide a seamless and efficient serial communication solution for a wide range of applications. This product stands out due to its capability to support four independent UART channels, making it an ideal choice for systems that require multiple serial interfaces while conserving valuable board space.

Each UART channel in the SC16C654BIA68,518 is fully equipped with 64-byte FIFOs, hardware and software flow control, and a comprehensive set of modem control signals that ensure smooth and reliable data transfer. This level of integration facilitates a reduction in system complexity and enhances data throughput, which is particularly beneficial in multitasking operating environments.

The device operates at a voltage range of 2.3V to 5.5V, making it versatile for various power supply requirements. It supports baud rates up to 5 Mbps, which is more than sufficient for most serial communication applications, including those in industrial automation, point-of-sale systems, and telecommunications.

One of the key features of the SC16C654BIA68,518 is its support for the enhanced features of the 16C550 UART, such as the automatic in-band flow control using programmable Xon/Xoff characters. This feature can significantly simplify software development and reduce CPU overhead by automating flow control procedures. Additionally, the device is compatible with the industry-standard 16C450 and enhanced 16C550 UART, ensuring easy integration into existing designs without significant modifications.

The package type for the SC16C654BIA68,518 is a 68-pin PLCC (Plastic Leaded Chip Carrier), which provides a compact footprint while allowing for robust and reliable connections to the printed circuit board. This package is well-suited for space-constrained applications where board real estate is at a premium.

Overall, the NXP SC16C654BIA68,518 is a feature-rich quad UART interface that offers designers a perfect blend of high functionality and space efficiency, making it a go-to choice for applications requiring multiple serial interfaces.
