Working Principles

The XR17D154CVTR-F is an integrated circuit that implements a serial UART interface. It utilizes a full-duplex communication protocol, allowing simultaneous transmission and reception of data. The IC incorporates hardware flow control, which uses the CTS (Clear To Send) and RTS (Request To Send) signals to regulate data flow between the microcontroller and peripheral devices.

The XR17D154CVTR-F also supports modem control signals, including DSR (Data Set Ready), DCD (Data Carrier Detect), and RI (Ring Indicator). These signals enable the IC to interact with external modems or other communication devices.

To conserve power, the IC features a sleep mode, where it enters a low-power state while maintaining the ability to wake up upon receiving a specific signal on the WAKEUP pin. The RESET pin allows for system initialization, ensuring proper operation during startup. Additionally, the INT (Interrupt) pin can be used to trigger interrupts in the microcontroller based on specific events.

Detailed Application Field Plans

The XR17D154CVTR-F finds application in various fields, including: 1. Industrial automation: Enables communication between microcontrollers and industrial sensors, actuators, and control systems. 2.
