UARTs (Universal Asynchronous Receiver Transmitter) can be used to achieve bidirectional serial data transmission between two devices, allowing them to exchange data. One of the most widely used UARTs is the Texas Instruments TL16CP754CIPM. It is a 3 volt UART transmitter/receiver that can be used for low rate battery powered applications such as PCMCIA cards and embedded systems. Here, we take a look at the application field and working principle of the TL16CP754CIPM.

Application Field of the TL16CP754CIPM

The TL16CP754CIPM is widely used for low voltage, low power applications such as PCMCIA cards and embedded systems. It also enables the use of 3.3 V PCMCIA cards in 5 V systems. Some of the main features of this device are:

• Low power consumption
• 128 bytes of FIFO
• Low bias current
• Low voltage operation
• Full handshake capability
• Supports 32 max. baud rate
• Programmable baud rate generator

The TL16CP754CIPM is ideal for use in applications such as personal computers, cellular phones, modems, and remote terminal equipments.

Working Principle of the TL16CP754CIPM

The TL16CP754CIPM is designed to allow bidirectional serial data transmission between two devices. The device works by continuously transmitting and receiving data characters to and from the receiving device. In order to properly receive data, the receiving device must be configured to the same data and baud rate as the transmitting device. This is accomplished by setting the proper baud rate generator (BRG) registers in the receiving device.

Once the two devices are properly configured, the TL16CP754CIPM works by continuously monitoring the transmit (TXD) and receive (RXD) signals. If a character is detected on either line, the device will check the status of the other line. If the other line is inactive, the character is read from the active line and the corresponding FIFO register is updated with the data. Once the data is read, the device then checks the other line to see if data is present. If data is present, the data is read and the corresponding FIFO register is updated.

The TL16CP754CIPM also supports full handshaking to ensure data integrity and accuracy. With full handshaking, the transmitting device will always send a data character, followed by an acknowledge character. Once the acknowledge character is sent, the receiving device will then send a response character, informing the transmitting device that the data was successfully received.

The TL16CP754CIPM is also equipped with an internal baud rate generator (BRG). This allows the device to be programmed to various baud rate settings, allowing it to be used in various applications and data transmission rates. The BRG also provides a number of additional features such as programmable data/parity/stop bits, parity and framing errors detection.

Conclusion

The TL16CP754CIPM is an effective UART transmitter/receiver that can be used for low rate battery powered applications such as PCMCIA cards and embedded systems. It features low power consumption, supports full handshaking, and is equipped with an internal baud rate generator (BRG) – allowing the device to be programmed to various baud rate settings. All these features make the TL16CP754CIPM an ideal choice for low voltage, low power applications.
