TL16C550DPFBG4

The TL16C550DPFBG4 is a dual-channel universal asynchronous receiver-transmitter (UART) integrated circuit (IC) produced by Texas Instruments. This device is designed to facilitate serial communication in embedded systems, enabling microcontrollers and other digital devices to communicate with peripherals such as modems, printers, and other serial devices.

Key Features:

1. Dual UART Channels: The TL16C550DPFBG4 includes two independent UART channels, allowing for simultaneous communication with two different devices. This is particularly useful in applications where multiple serial connections are required.

2. Data Format: The device supports various data formats, including 5, 6, 7, or 8 data bits, along with optional parity bits and 1 or 2 stop bits. This flexibility allows it to accommodate a wide range of communication protocols.

3. Baud Rate Generation: The TL16C550DPFBG4 can generate baud rates up to 115.2 kbps, making it suitable for high-speed data transmission. The baud rate can be configured through programmable registers.

4. FIFO Buffer: The integrated 16-byte FIFO (First In, First Out) buffer for both transmit and receive operations helps to manage data flow efficiently, reducing the risk of data loss during high-speed communication.

5. Interrupt Control: The device features an interrupt-driven architecture, allowing it to signal the host processor when data is available to read or when the transmit buffer is ready to accept more data. This reduces CPU overhead and improves system efficiency.

6. Power Management: The TL16C550DPFBG4 includes power-saving features, such as a low-power mode, which helps to extend battery life in portable applications.

7. Operating Voltage: The IC operates within a voltage range of 3.0V to 5.5V, making it compatible with a variety of microcontroller systems.

8. Package Type: The TL16C550DPFBG4 is available in a 28-pin PLCC (Plastic Leaded Chip Carrier) package, which is suitable for surface-mount technology (SMT) applications.

9. Temperature Range: The device is rated for operation over a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial and automotive applications.

Applications:

The TL16C550DPFBG4 is commonly used in various applications, including:

• Embedded systems for data acquisition and control.
• Communication interfaces in industrial automation.
• Point-of-sale systems.
• Networking equipment.
• Consumer electronics requiring serial communication.

Conclusion:

The TL16C550DPFBG4 from Texas Instruments is a versatile and robust UART solution that provides reliable serial communication capabilities for a wide range of applications. Its dual-channel design, flexible data format support, and efficient buffering make it an excellent choice for developers looking to implement serial communication in their projects.
