SC16IS762IPW,112

The SC16IS762IPW,112 is a dual-channel serial communications interface (UART) controller designed for applications requiring flexible serial port expansion. This integrated circuit functions as a bridge between parallel microcontroller buses and serial communication protocols, enabling devices to add multiple independent serial channels without consuming native UART resources on the main processor. This component belongs to the SC16IS76x family of serial interface ICs, which are widely used in industrial control systems, data acquisition equipment, point-of-sale terminals, and embedded systems where additional serial ports are needed. The dual-channel architecture allows simultaneous independent operation on two separate serial channels, making it suitable for applications that must manage multiple serial devices or protocols concurrently. The device communicates with host microcontrollers via industry-standard parallel interfaces, typically I2C or SPI, depending on the specific variant within the family. This parallel interface approach simplifies integration into systems where adding discrete UART hardware would be impractical. Engineers often specify these devices when legacy equipment using RS-232 or RS-485 serial communications must interface with modern microcontroller platforms that have limited native serial port availability. Key characteristics that influence design decisions include the IC's onboard crystal oscillator support, integrated baud-rate generator, and configurable interrupt logic. The component is housed in a small-footprint surface-mount package, which is typical for the SC16IS76x series, allowing integration into space-constrained PCB designs common in industrial and portable equipment. Engineers select this particular part number when they need a reliable, well-established solution for serial port multiplication in embedded systems. The SC16IS76x family has extensive software driver support across multiple operating systems and development platforms, reducing development time and risk compared to less common alternatives. The dual-channel configuration provides flexibility for applications that might require different serial protocols or communication rates on separate channels. The component operates from standard logic supply voltages typical of modern microcontroller systems. Its integration of multiple functions—oscillator, baud-rate generation, and dual independent channels—onto a single IC reduces component count and simplifies board layout compared to discrete implementations. This part is commonly found in industrial automation controllers, embedded systems requiring serial device connectivity, test and measurement equipment, and communication gateways where adding multiple asynchronous serial ports to a microcontroller-based design is essential. The established market presence and broad compatibility of the SC16IS76x family make it a standard choice for engineers implementing reliable serial communication expansion in embedded applications.
