The NXP SC28L92A1 is a highly-integrated Dual Universal Asynchronous Receiver/Transmitter (DUART) designed to facilitate serial communication in a variety of applications. This advanced integrated circuit is ideal for systems that require multiple UART channels, offering a compact and efficient solution for serial data exchange.

Key Features

• Dual Channel: The SC28L92A1 features two independent full-duplex UARTs, each with its own set of registers and flags. This allows for simultaneous bi-directional communication on two separate serial interfaces.
• Baud Rate Generation: Each UART channel supports a wide range of programmable baud rates, ensuring compatibility with various communication standards and facilitating easy integration into existing systems.
• Flexible Data Format: Users can configure each UART to handle data frames with 5 to 8 data bits, 1 or 2 stop bits, and even or odd parity. This flexibility makes the SC28L92A1 adaptable to various communication protocols.
• Interrupt-Driven Operation: The device offers comprehensive interrupt features for efficient data handling, minimizing CPU overhead by alerting the system only when attention is needed.
• On-Chip FIFOs: Each UART is equipped with a 16-byte FIFO for both transmit and receive operations, reducing the potential for data overrun and improving overall data throughput.
• Low Power Modes: The SC28L92A1 supports multiple power-saving modes, including a reduced power mode and a sleep mode, making it suitable for power-sensitive applications.

Applications

The versatility of the NXP SC28L92A1 makes it an excellent choice for a broad range of applications, including but not limited to:

• Industrial control systems
• Networking equipment
• Point-of-sale terminals
