SC16C654DBIB64,128

The SC16C654DBIB64 and 128 are both UARTs (Universal Asynchronous Receiver Transmitter). UART is a piece of hardware used to communicate over serial transmission lines, such as RS232, RS485, and RS422. UARTs are often used to communicate between two devices, such as to control a motor or a programmable logic controller (PLC).The SC16C654DBIB64 and 128 both have the same core, but have different options. The 64 has 64 bytes of general purpose RAM and the 128 has 128 bytes of RAM. Both UARTs have a 32 character transmit/receive FIFO (First In First Out) buffer, which is an advanced feature that allows data to be stored temporarily before being transmitted or received. The FIFO also features advanced data control and flow control for point-to-point and multi-node applications.The SC16C654DBIB64 and 128 are used for a variety of applications, such as for embedded and industrial control, Metro Ethernet, consumer, automotive, and communication interface applications. They are also used in data terminal systems and point-of-sale terminals.The working principle of the SC16C654DBIB64 and 128 is quite simple. Data is transmitted between two devices over a single pair of wires, which is known as an asynchronous serial data line. This type of transmission is also referred to as an RS232, RS485, or RS422 connection. UARTs use a serial bit stream to send and receive data, which is synchronous, meaning that the timing of the data is important. Each end of the UART must know when data is being sent, and each must be able to interpret the signals coming from the other.UARTs typically use 4 wires: a transmit line (Tx), a receive line (Rx), an optional Request To Send (RTS) line, and an optional Clear To Send (CTS) line. The Tx and Rx lines are used for sending and receiving data, while the RTS and CTS lines are for flow control and handshake.In conclusion, the SC16C654DBIB64 and 128 are UARTs that are used for a variety of applications, such as embedded and industrial control. They use 4 wires to facilitate sending and receiving data, with an optional Request to Send and Clear to Send line for flow control and handshake. The 64 and 128 each have different RAM sizes, but otherwise offer the same features, making them great choices for a number of applications.
