TL16C550CPTRG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550CPTRG4 is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments. It features 16-byte transmit and receive FIFOs with three additional error status bits per byte in the receiver buffer. The device supports data rates up to 1 Mbaud with a maximum clock rate of 16 MHz. It operates on supply voltages of 3.3 V or 5 V, with recommended ranges of 3.0–3.6 V and 4.75–5.25 V respectively. The component is housed in a 48-pin LQFP package and includes programmable auto-RTS and auto-CTS autoflow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Programmable autoflow control using auto-RTS and auto-CTS modes to manage serial data flow and reduce software overhead.
• Integrated 16-byte FIFOs for both transmission and reception to minimize CPU intervention during data transfers.
• Compatible register set with legacy TL16C450 devices, allowing direct software migration without code changes.
• Supports DMA signaling via TXRDY and RXRDY pins for efficient high-speed data movement.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring reliable serial data exchange.
• Embedded controllers needing UART interfaces with hardware flow control.
• Modem interfacing applications utilizing standard modem control signals.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the 'PTR' designation corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure the ordering part number matches the exact voltage grade and temperature range specifications needed for the target application environment.

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 TL16C550B and maintains backward compatibility with TL16C450 software. Consider the 48-pin LQFP package constraints and verify that the system clock can support the desired baud rate generation divisors up to 65535.
