TL16C550DIPTG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550DIPTG4 is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments, housed in a 48-pin Low-Profile Quad Flat Package (LQFP). It supports operation with supply voltages of 2.5 V, 3.3 V, and 5 V. The device features programmable auto-RTS and auto-CTS autoflow control to manage serial data flow. It includes 16-byte transmit and receive FIFOs, a programmable baud rate generator, and independent interrupt capabilities. The maximum clock rate reaches 24 MHz for 5-V operation, supporting baud rates up to 1.5 Mbaud.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated autoflow control with programmable auto-RTS and auto-CTS functions
• Dual 16-byte FIFOs for receiver and transmitter buffering
• Programmable baud rate generator with divisors from 1 to 65535
• Independent interrupts for line status, data set, and modem control

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial-to-parallel and parallel-to-serial data conversion in embedded systems
• Modem interface circuits requiring hardware flow control
• High-speed asynchronous communication links with DMA support

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the component authenticity against the official Texas Instruments datasheet specifications. Confirm that the 48-LQFP package matches the required PCB footprint dimensions. Ensure the operating voltage range aligns with the system's power supply rails before integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this model when software overhead reduction via autoflow control is critical. The 48-pin LQFP package is suitable for surface-mount assembly. Consider the 24-MHz clock limit if higher baud rates are required at lower supply voltages.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component is part of the TL16C550D family, serving as an upgrade to the TL16C550C. It maintains functional equivalence with the legacy TL16C450 on power-up while offering enhanced speed and multi-voltage support. The 'DI' suffix indicates the specific pinout and package variant within the series.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DIPT is a non-green equivalent without the G4 suffix. The TL16C550CIPTRG4 offers similar functionality but operates at lower maximum speeds.
