UARTs (Universal Asynchronous Receiver Transmitter) are commonly used to enable communication between computer peripherals, such as modems, and a host. The SC16C652IB48,128 is an interface device that combines the functions of two independent UARTs into one interface and includes a 16C52-B processor for enhanced value, performance, and cost savings. It offers 128-byte FIFOs for both receive and transmit that provide buffering for incoming data and minimize data excursion for improved communications.

The main application field of SC16C652IB48,128 is in computer peripheral devices. This device is a cost-effective solution for communications between computer peripheral devices, such as modems, scanners, printers, and other components. It is particularly useful in applications where multiple devices need to communicate simultaneously.

The working principle of the SC16C652IB48,128 is based on the concept of “asynchronous” communication. In asynchronous communication, the data is transferred between two devices at different rates. The primary advantage of this type of communication is that the devices do not have to be synchronized, enabling them to communicate at different bit lengths and speeds.

The SC16C652IB48,128 provides data rate auto-baud support for baud rates from 300 baud up to 9.6K baud, as well as external clock support for higher baud rates. It offers two independent UARTs, each with its own 64-byte FIFO buffers, and an auto-baud timer that can be used to synchronize incoming data streams. It also includes a Register Based Linear Interface (RBLI) for parallel access to registers.

The SC16C652IB48,128 also includes additional features such as a built-in 9-bit framing for serial communications, use of even and odd parity bit encoding, and generation of interrupts to indicate completion of data transfers. The device also supports a standard hardware handshake protocol and sleep modes to minimize power consumption.

In summary, the SC16C652IB48,128 is a versatile interface device capable of providing high-speed asynchronous communication between computer peripherals. It provides 128-byte FIFOs for both receive and transmit data, auto-baud functionality, and hardware handshake support, as well as low-power sleep mode to minimize power consumption.
