Working Principle

The ST16C650ACQ48-F UART utilizes a 16-bit register interface for full-duplex communications. It features a 16-level FIFO and a wide range of configurable baud rates. The data is transmitted from the transmitter (Tx) to the receiver (Rx) using asynchronous serial communication protocol—the Universal Asynchronous Receiver/Transmitter (UART). Asynchronous serial communication allows the two devices to control their own data transmission and receive data at different times.

The ST16C650ACQ48-F UART offers a number of features to facilitate data transmission, including:

• Automatic data flow control with RTS and CTS signal.
• Time-out detection with RTS signal.
• Programmable baud rate up to 921.6 Kbaud.
• Configurable data bits, stop bits, and parity.

The ST16C650ACQ48-F is designed with a switched mode power supply (SMPS) architecture, which makes it very energy efficient. The device has a low-power operating mode that allows it to be used in portable and battery-powered devices. The ST16C650ACQ48-F is also designed with an HCSL interface for reduced electromagnetic interference (EMI).

Conclusion

The ST16C650ACQ48-F is a cost-effective, hassle-free UART solution for many applications. It is ideal for industrial, consumer and communication applications. The device’s switched mode power supply architecture and low-power operating mode make it suitable for battery-powered applications. Furthermore, its HCSL interface helps reduce EMI from the system. The ST16C650ACQ48-F UART can transmit and receive data at high baud rates up to 921.6 Kbaud. And its 16-level FIFO facilitates full-duplex data transmission.
