TL16C550CIPT

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550CIPT is an asynchronous communications element (ACE) from Texas Instruments, designed for serial data transfer in industrial and embedded systems. It features a single UART channel with 16-byte transmit and receive FIFOs to reduce CPU overhead. The device supports baud rates up to 1 Mbaud with a maximum clock rate of 16 MHz. It operates on both 3.3 V and 5 V supply voltages within specified ranges. The component is housed in a 48-pin LQFP package and is rated for an extended operating temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrated autoflow control using programmable Auto-RTS and Auto-CTS modes to manage serial data flow and prevent buffer overruns.
• Includes 16-byte FIFO buffers for both transmission and reception, storing error status bits alongside received data.
• Provides complete modem control capabilities including CTS, RTS, DSR, DTR, RI, and DCD signals.
• Features a fully prioritized interrupt system with independent control for transmit, receive, line status, and data set events.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication links.
• Embedded controllers needing high-speed UART interfaces with DMA support.
• Telecommunications equipment utilizing standard asynchronous protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) and 'PT' denotes the 48-LQFP package. Confirm that the ordering part number matches the exact voltage and package requirements for your design. Cross-reference the manufacturer's latest datasheet for any potential revisions or obsolescence notices before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single-channel UART with hardware autoflow control is required. Ensure the system clock can provide up to 16 MHz for maximum baud rate performance. Verify compatibility with existing TL16C450 software if legacy code migration is planned, as the register sets are functionally identical upon reset.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C550CIPT belongs to the TL16C550C family, which serves as a functional upgrade to the TL16C550B and TL16C450. It retains backward compatibility with older software while adding advanced FIFO and autoflow features. The 'CI' designation specifically identifies the industrial temperature variant within the broader TL16C550C product line.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550DIPT is a direct replacement offering the same functionality but limited to commercial temperature ranges (0°C to 70°C). For lower voltage applications, the TL16C550CIPTRG4 provides equivalent performance in a tape-and-reel packaging format.
