NXP SC26C94C1A Quad UART Interface IC

The NXP SC26C94C1A is a versatile quad-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit, designed for high-performance serial communication applications. This powerful IC is an ideal solution for systems that require multiple serial I/O ports with minimal board space and power consumption.

Each of the four UART channels in the SC26C94C1A is fully independent and features a programmable baud rate generator, capable of supporting a wide range of communication speeds. The device is compatible with the industry-standard SC16C550 UART, offering enhanced features such as a larger FIFO, additional status and control registers, and a programmable character length of 5 to 8 bits.

The SC26C94C1A provides extensive modem control capabilities, making it suitable for modem interface applications. It includes standard modem handshake signals that are fully programmable, allowing for flexible control of data transmission and reception. The chip also offers a complete modem signaling interface, which includes RI, DSR, DCD, CTS, and RTS lines.

The FIFOs in each UART channel have a depth of 8 bytes for both transmit and receive, reducing the potential for data overrun and minimizing the need for intervention by the host processor. This is especially beneficial in multitasking environments where the CPU can be freed up to perform other tasks while the SC26C94C1A handles the serial data communication.

The SC26C94C1A operates over a wide voltage range and has a low power consumption profile, which is critical for battery-operated portable devices. It is packaged in a compact 52-pin PLCC (Plastic Leaded Chip Carrier) or QFP (Quad Flat Package), ensuring a small footprint on the PCB and ease of integration into a variety of designs.

Whether you're designing an industrial control system, a complex networking infrastructure, or a high-speed data acquisition unit, the NXP SC26C94C1A offers the reliability, flexibility, and performance needed to meet the rigorous demands of serial data communication.
