The XR82C684CJTR-F is a highly-configurable Inter Integrated Circuit (IIC) that interfaces peripherals with microcontrollers. It’s part of Xicor’s product family of IICs and is especially optimized for use with the 81C88C microcontroller manufactured by Intel. It’s a single controller that has 16 8/16-bit registers that are configured as a Universal Asynchronous Receiver/Transmitter (UART). The XR82C684CJTR-F is primarily used in systems that require serial data transmission or reception.

The 16 8/16-bit registers in the XR82C684CJTR-F provide the configuration and control necessary for all standard UARTS. It can be used to manage both the transmitting and even reception of serial communication. Additionally, the chip can be used as a direct replacement for UARRTS that are integrated in other microcontroller chips. Such support allows for the UART to send and receive data from multiple sources and peripherals as well as to accept data from multiple sources and peripherals.

The XR82C684CJTR-F can be configured for a variety of serial communication protocols including RS-232, RS-422, and RS-485. It also ensures data integrity by checking for errors during data transmission and receiving. The chip also supports various types of parity checking and supports a range of receiver sensitivity settings. Additionally, the XR82C684CJTR-F can be used to handshake with peripherals, which prevents data loss when sending and receiving large amounts of data. The chip also supports auto flow control and adjustable data rate options.

The XR82C684CJTR-F is used in a number of different applications. It is used in digital signal processing systems that require high friction serial communication. Additionally, it is used in embedded industrial control systems and in telecommunications equipment where high speeds and data integrity are critical. It is also used in automotive applications and in security systems as an alternative to RS-232 and other legacy protocols.

The working principle of the XR82C684CJTR-F is based on the principles of asynchronous serial communication. Data is transferred between the chip and connected peripherals by means of an 8-bit serial bus. The transmission of data is organized in blocks of 8 bits (or frames) and is composed of a start bit, data bits, stop bit and parity bit. The XR82C684CJTR-F will take each frame received and convert it into a 16-bit data word which can then be sent to the microcontroller.

The data rate of the XR82C684CJTR-F can be adjusted to meet the needs of different applications. The chip has adjustable baud rate dividers that can be used to set the speed of data transmission. Additionally, the chip supports a wide range of data formats including 7-bit, 8-bit, 9-bit, and even some custom formats.

As a Universal Asynchronous Receiver/Transmitter, the XR82C684CJTR-F provides a reliable and efficient means of interfacing peripherals with microcontrollers. It supports a range of serial communication protocols and can be easily configured to operate at different data rates. Moreover, it ensures data integrity by checking for errors during data transmission and reception.
