The ST16C654IQ100TR-F is a universal asynchronous receiver transmitter (UART) that is used in many modern, contemporary and emerging designs. This UART enables communication between serial data ports and consists of one input and one output register, while providing the interface necessary to connect the two together. ST16C654IQ100TR-F is a member of the STC650 family of UARTs, distributed by STMicroelectronics which can be applied in several applications.

The applications of the ST16C654IQ100TR-F UART include automotive embedded controllers, industrial automation systems, data acquisition systems, and medical equipment. This UART can also be used in consumer electronic systems such as HDTV, DVD players, set-top boxes, networking equipment, and wireless applications. Furthermore, the ST16C654IQ100TR-F also works in certain industrial and automotive applications. In some instances, it can also be used to provide control signaling in telecom and radar systems.

The ST16C654IQ100TR-F UART supports a wide range of data transfer and communications features. It has an 8-bit to 16-bit data word length and can handle data rates from 9.6 to 12 megabits per second. It also integrates a programmable timer, programmable interrupt sources and a 4-bit status register, which can be used for various operations. This UART also has a programmable FIFO (First-In-First-Out) buffer, which allows it to queue incoming data for efficient storage and processing.

The main features and specifications of the ST16C654IQ100TR-F UART include a 16-bit data word length, programmable FIFO and 16-bit baud rate generator. It operates with a maximum data rate of 12 Mbps and supports isochronous data transfers. Additionally, it has a Programmable Time out Interace (PTI), making it ideal for designing systems with high levels of real-time performance. The FIFO in the ST16C654IQ100TR-F also allows for data transfer without the need for constant polling of data ports.

In terms of operation, the ST16C654IQ100TR-F UART uses various components to perform its job. These components are essentially divided into two main categories: the transmitter and the receiver. The transmitter portion of the UART works by converting digital data into serial format, which can be sent over a serial communication interface such as RS-232, RS-485, or Ethernet. This converted data is then received by the receiver, which converts it back into digital format for storage and processing.

The incoming data from the receiver is then passed to the FIFO buffer. The buffer stores the data until the timer expires, which then triggers the UART to move the data to the CPU in a predetermined manner. The timer can be set to specific intervals, allowing the UART to adjust the rate of data transfer to match the processor’s speed. Once the data has been transferred, an interrupt signal is sent to the processor, which allows the processor to start processing the data.

In summary, the ST16C654IQ100TR-F UART is a powerful UART that offers fast data rate transfers and can be used in many different applications. Its FIFO buffer allows it to efficiently store data while its PTI interface enables high levels of real-time performance. Moreover, its several components help in converting data from digital to serial format and vice-versa. Thanks to its wide range of features and specifications, the ST16C654IQ100TR-F is an ideal solution for applications that require reliable communication between serial data ports.
