The TL16C550BPTR is a high-performance Universal Asynchronous Receiver/Transmitter (UART) from Texas Instruments, designed to meet the communication needs of embedded systems. This integrated circuit facilitates serial communication by converting bytes from the system's parallel bus to a serial form, which can then be transmitted over communication lines like RS-232, RS-485, or RS-422.
Key Features and Benefits
- Enhanced Data Rates: The TL16C550BPTR offers a programmable baud rate generator capable of dividing the timing reference clock by divisors of 1 to (2^16 - 1), allowing precise selection of baud rates.
- FIFO Buffers: It includes 16-byte FIFOs for both transmit and receive operations, which helps to reduce the overhead of CPU data transfers and improves system efficiency by allowing more time for processing other tasks.
- Automatic Flow Control: The device supports automatic hardware and software flow control, which prevents data loss during high-speed data transfers and ensures reliable communication.
- Programmable Character Lengths: It can be programmed for 5, 6, 7, or 8-bit character lengths to accommodate various data formats and protocols.
- Modem Control Capability: The TL16C550BPTR has a complete modem control capability and a set of four dedicated pins for this purpose, making it suitable for modem interface applications.
- Low Power Consumption: Designed with power efficiency in mind, it operates with a low supply voltage and has a power-down feature to conserve energy when not in active use.
Applications
The TL16C550BPTR is ideal for a wide range of applications that require reliable serial communication. It is commonly used in:
- Industrial control systems
- Point of sale terminals
- Networking equipment
- Computer peripheral interfacing
Package and Quality
