NXP SC28C94A1A,512 Quad UART Interface IC
The SC28C94A1A,512 is a high-performance Quad Universal Asynchronous Receiver/Transmitter (UART) integrated circuit from NXP Semiconductors. This device is designed to provide efficient serial communication in a variety of applications, including telecommunications, networking, and industrial markets.
The SC28C94A1A,512 features four independent UART channels, each capable of handling serial data rates up to 5 Mbps. This makes it an ideal choice for systems that require multiple high-speed serial interfaces. Each UART channel is equipped with a 16-byte transmit and receive FIFO, which helps to reduce CPU overhead by buffering data and minimizing the need for frequent service routines.
This device supports a wide range of protocols and data formats, allowing it to be used in diverse applications. It offers programmable character lengths, stop bits, and parity, as well as hardware and software flow control. The SC28C94A1A,512 also includes a modem control interface, which provides additional functionality for modem applications.
The SC28C94A1A,512 operates over a single 5V power supply, and its low-power consumption makes it suitable for power-sensitive designs. It is available in a 52-pin PLCC (Plastic Leaded Chip Carrier) package, which ensures a compact footprint and ease of integration into system designs.
For design flexibility, this Quad UART IC features a programmable baud rate generator and is capable of operation in normal, automatic echo, local loopback, and remote loopback modes. Its versatility is further enhanced by the inclusion of an on-chip status register, which provides error indications and operational status of the device.
Overall, the SC28C94A1A,512 from NXP is a robust and versatile solution for complex communication tasks requiring multiple UART interfaces. Its integration of four UARTs into a single chip not only saves space but also simplifies design and reduces overall system costs, making it a valuable component in any designer's toolkit.
