The CY74FCT191ATSOCT is a high-speed dual universal asynchronous receiver/transmitters (UARTs) with internal automatic flow control that can be used in a variety of applications. It is a low-power, low-cost logic device that is highly compatible with most CMOS products. The CY74FCT191AT SOCT is typically used in digital signal processing (DSP) and communication control systems, such as dial-up modems, cellular systems, and consumer electronics. The device has small size, low power consumption, low-cost, and fast transmit/receive switching time.

The CY74FCT191ATSOCT provides two independent UARTs, each with an 8-bit character, a 9-bit character, or a 10-bit character format. Both UARTs have 1.5 stop bits, 1 start bit, and 8-bit data randomization. The UART provides automatic flow control and operates up to 8-bit data format. Each UART has a transmit/receive FIFO that contains 16 characters and provides an additional 3-bit order code to indicate the data status. You can select the data length and order of the UARTs independently.

The C Y74FCT191AT SOCT UARTs support a variety of data rates up to 115,200 baud. They are capable of operation with a wide range of several operating frequencies and provide a selectable invert serial data mode of operation. The CY 74FCT191ATSOCT also includes nine control functions and nineteen status and result indicators.

In addition to the functions of a normal UART, the CY74FCT191AT SOCT also incorporates the advantages of a dual counter/dividers. The two counters/dividers can operate independently with separate counters for doing different tasks. The first counter is used for splitting the clock with a divide-by-Ncount ratio and can generate either a synchronous or asynchronous clock. The second counter is used for bit interpolators and can interpolate the data in a chosen format. This is useful when attempting to synchronize the data streams. The CY74FCT191AT SOCT also includes an interrupt generator that can be used to detect errors, receive data, and control signals.

The CY 74FCT191ATSOCT is ideal for any application requiring low-power, low-cost multiplexing of digital data and communications control data. It is suitable for use in DSP and communications systems as well as in any embedded system requiring asynchronous serial data communications with high throughput. It supports a variety of data rates and formats, making it an invaluable tool for digital data representation and communications control.
