UARTs (Universal Asynchronous Receiver Transmitter) are digital circuit systems used for asynchronous transmission and reception of data over a serial communication line. ST16C1550IJ28TR-F is a UART manufactured by STMicroelectronics, which is a world-leading semiconductor manufacturer based in Europe. This article looks at the application fields and working principles of this UART chip.

Applications of ST16C1550IJ28TR-F

ST16C1550IJ28TR-F is an UART integrated circuit (IC) from STMicroelectronics that provides communications solutions for a variety of embedded system designs. This UART is used in applications such as automotive, industrial, medical, and consumer electronics which require reliable serial communication. Features of this UART include:

• Up to 10 Mbps data rate
• Enhanced Inter-Integrated Circuit (I²C) functionality
• Interface with Smart Card I/O, serial buses
• Open-drain output for secure serial communication
• Supply voltage range of 2.6V - 3.6V
• Temperature range of -40°C to +125°C

This UART is used as a bridge between different communication interfaces. It enables devices to exchange data reliably, supports networking protocols such as Ethernet, and operates at low power. Additionally, it is certified with UL, CSA, and TUV-S safety certifications.

Working Principle of ST16C1550IJ28TR-F

The ST16C1550IJ28TR-F UART operates in full duplex mode with a protocol known as the Serial Peripheral Interface (SPI). It is a two-wire protocol that transmits information in a master-slave configuration. The master controls the clock and receives data from the slave. The slave can send data and receive data from the master. The data exchange is asynchronous, meaning that the transfer of data is not synchronized to a clock, but occurs on an event or data change.

The ST16C1550IJ28TR-F operates in a bit-banging mode where it reads in data by toggling the lines between low and high states. When the lines go high, the UART reads in data, and when the lines go low, the UART sends out data. This is done using the UART\'s transmitter and receiver. The transmitter can send out data at up to 10 Mbps, and the receiver can receive data at up to 10 Mbps.

The UART also has a built-in timer for monitoring the communication between the master and slave devices. This timer will trigger an interrupt signal when the communication between the devices is not within a predefined limit. This will aid in debugging any potential communication errors and help ensure reliable communication.

Conclusion

ST16C1550IJ28TR-F is a UART IC developed by STMicroelectronics that provides reliable communication in a variety of applications ranging from automotive to consumer. It operates in full duplex SPI mode, has a data rate of up to 10 Mbps, and is certified with UL, CSA, and TUV-S safety certifications. Additionally, it has a built-in timer for monitoring the communication between the master and slave, which helps in debugging any communication errors.
