Working Principle

The HSP43216JC-52Z is a combined UART and SPI interface chip. A basic view of the UART and SPI working principles is provided here. More detailed information can be found in the chip’s datasheet.

UART

The UART, or universal asynchronous receiver/transmitter, is a chip which is responsible for converting serial data into parallel data and vice versa. This allows for the data to be sent and received between two devices. The UART consists of several components, including an input buffer, an output buffer, a shift register and an ACK line. The following is a brief explanation of how these components work together.

• The input buffer is responsible for receiving data from the sending device. It is then stored in the shift register until it is transmitted by the output buffer.
• The output buffer is responsible for sending data to the receiving device. It takes data from the shift register and transmits it to the receiving device.
• The shift register is used to store data as it is sent and received by the input and output buffers. It is responsible for moving data from one buffer to the other.
• The ACK line is a line used to notify the sending device that the data has been received. When the receiving device receives the data, it sends a signal through the ACK line back to the sending device. This signal lets the sending device know that the data was received successfully.

SPI

The SPI, or serial peripheral interface, is another chip which is responsible for data exchange between two devices. Unlike the UART, the SPI is a synchronous interface which requires both devices to be in sync. This means that both devices must have the same clock speed and data rate. The SPI consists of several components, including an interface controller, a clock generator and an output buffer. The following is a brief explanation of how these components work together.

• The interface controller is responsible for sending and receiving commands between the two devices. It sends the commands to the receiving device via the output buffer.
• The clock generator is responsible for generating a signal in order to keep the two devices in sync. It generates a signal which is sent to both devices so that they can stay in sync.
• The output buffer is responsible for sending data from the sending device to the receiving device. It takes data from the interface controller and sends it to the receiving device.

Conclusion

The HSP43216JC-52Z is an 8-pin single chip Universal Synchronous/Asynchronous Receiver/Tranceiver (USART) which combines the functionality of a transmit/ receive universal asynchronous receiver/transmit (UART) and a serial peripheral interface (SPI) in an 8-pin package.
