TL16C550DIPT

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550DIPT is a single-channel Asynchronous Communications Element (ACE) manufactured by Texas Instruments, housed in a 48-pin LQFP package. It supports data rates up to 1.5 Mbaud with a 24-MHz clock at 5 V operation. The device features 16-byte transmit and receive FIFOs with error status bits. Operating voltage ranges from 4.5 V to 5.5 V, with a typical operating current of 10 mA. It includes programmable baud rate generation, autoflow control, and independent interrupt capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Autoflow control mechanism utilizing auto-RTS and auto-CTS to manage serial data flow and reduce software overhead.
• Programmable baud rate generator capable of dividing reference clocks to support various communication speeds.
• Integrated 16-byte FIFOs for both transmission and reception to minimize CPU intervention.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial-to-parallel and parallel-to-serial data conversion in computer systems
• Modem interface circuits requiring hardware flow control
• Embedded communication links needing reduced processor management

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements before integration. Cross-reference the datasheet revision date to confirm feature availability and electrical specifications match the intended design constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with hardware autoflow control is required. It serves as a functional upgrade to the TL16C550C, offering higher speed capabilities. Consider the 48-pin LQFP package dimensions for PCB layout. Verify that the host system can accommodate the 3-state TTL drive capabilities and address decoding logic specified in the terminal assignments.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C550D series represents a speed and voltage upgrade over the TL16C550C while maintaining functional equivalence to the earlier TL16C450. It is designed to relieve CPU overhead through advanced FIFO buffering and autoflow control. The device is part of Texas Instruments' asynchronous communications element family, providing comprehensive modem control and status reporting.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DIPT is functionally equivalent to the TL16C550D. For pin-compatible alternatives within the same family, consider the TL16C550C variants, though they operate at lower maximum speeds. Verify register compatibility if migrating from legacy TL16C450 designs.
