NXP SC26C92C1B,557 Dual Universal Asynchronous Receiver/Transmitter (DUART)

The NXP SC26C92C1B,557 is a high-performance, dual-channel Universal Asynchronous Receiver/Transmitter (DUART) designed for use in a wide range of communication applications. It is a versatile integrated circuit that facilitates serial communication by converting parallel data from a data bus into serial form and vice versa. This product is a part of NXP's renowned series of communication controllers, which are known for their reliability and advanced features.

The device features two independent full-duplex channels, each with its own set of registers and control logic. This allows the SC26C92C1B,557 to handle serial data communication for two separate serial ports simultaneously, making it an ideal choice for systems that require multiple communication channels without the need for additional chips.

Each channel of the SC26C92C1B,557 supports a wide range of baud rates and includes a programmable baud rate generator. It also provides support for various serial data formats, including 5, 6, 7, or 8 data bits, 1 or 2 stop bits, and even or odd parity. The flexibility in configuration makes this DUART suitable for interfacing with a variety of peripherals and networks.

In addition to its versatile serial communication capabilities, the SC26C92C1B,557 includes several other features that enhance its functionality. These include a FIFO (First In, First Out) buffer for each transmitter and receiver, reducing the overhead on the host processor by allowing multiple characters to be queued for transmission or read after reception. There are also multiple interrupt sources for each channel, which can be programmed to alert the host processor of various events, such as data transmission completion, data reception, and errors.

The NXP SC26C92C1B,557 is housed in a compact package, making it suitable for space-constrained applications. It operates over a wide temperature range and has low power consumption, which is critical for portable and battery-operated devices. With its robust feature set, this DUART is an excellent choice for implementing serial communication in industrial control systems, networking equipment, point-of-sale terminals, and many other embedded systems.
