The SCC2698BC1A84,518 is a standard-grade UART (Universal Asynchronous Receiver Transmitter) integrated circuit, corresponding to the Electronic Industries Association (EIA) standard RS-232C. The chip is used to communicate serial data, with a baud rate of up to 960 Kbps, between two (or more) digital electronic devices, such as computers and peripherals, or industrial equipment.

To better understand the SCC2698BC1A84,518, it’s helpful to be familiar with some of the basic components and operations of the UART in general. Most implementations of the UART involve the following functional blocks: a transmitter, a receiver, and a protocol state machine (PSM) to monitor and control the data flow in the link.

The transmitter (TX) converts digital signals into serial bit streams, while the receiver (RX) is responsible for converting the serial stream back into discrete digital values. The UART uses a parallel concept, in which multiple bits of data are sent simultaneously, rather than serially — i.e., one bit at a time. The UART also performs functions such as parity checks and framing (determining the start and end of each data transmission), which are necessary for reliable data transfer.

These functions are monitored and maintained by the PSM, which is responsible for controlling the link’s timing, the number of bits transmitted, the type of signal sent, the encoding used, and the parity checking. The PSM also serves to synchronize the transmitted and received signals and to detect any errors in the signal pattern.

The SCC2698BC1A84,518 is designed to meet the most demanding requirements of industrial, consumer, and commercial applications. It features a low-power design, operating at a maximum of 2.5V, and works with most popular microcontrollers, including those manufactured by TI, Atmel, and Freescale. It has a high-speed data rate of up to 960 Kbps and provides the user with a flexible and easy-to-use UART interface. The chip also includes an on-chip counter/timer, which can be used for generating various timing intervals.

The SCC2698BC1A84,518 supports a variety of serial data formats, including 8/N/1, 7/E/1, 8/O/1, 8/E/1, 8/M/1, 9/N/1, and 7/O/1. In addition, it can accommodate different interface speeds, from 9600 to 960 Kbps. The UART supports 8-bit data, automatically handles framing and parity checking, and supports full-duplex communication, allowing data to be sent and received simultaneously.

The chip also provides an advanced feature set, including a configurable RX FIFO buffer and automatic power-down mode with selectable timeout periods. The RX FIFO buffer can handle up to 8 bytes of data and can be used to reduce the load off the system processor. The power-down mode allows the chip to consume less power when not in use, while the timeout period helps to further conserve power.

The SCC2698BC1A84,518 is ideal for interfacing with serial expansion boards and other application-specific integrated circuits (ASICs). It is typically used in embedded systems where its low power consumption, high performance, and built-in error checking are essential for reliable data transfer. The UART also supports a wide range of applications, including RS-232, RS-422, and RS-485 communication, and can be found in a variety of consumer, industrial, and automotive products.
