TL16C550CIFNRG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550CIFNRG4 is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments. It features 16-byte transmit and receive FIFOs with error status bits, supporting data rates up to 1 Mbaud with a 16-MHz clock. The device operates on 3.3 V or 5 V supplies within a commercial temperature range of 0°C to 70°C. Packaged in a 44-pin PLCC (FN) surface-mount format, it includes programmable baud rate generation, autoflow control, and full modem control signals.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Programmable autoflow control using auto-RTS and auto-CTS modes to manage serial data flow and prevent overrun errors.
• Integrated 16-byte transmit and receive FIFOs that reduce CPU software overhead during high-speed data transfers.
• Full compatibility with existing TL16C450 register sets and software upon power-up for seamless integration.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring reliable serial data exchange
• Embedded controllers needing direct UART interface capabilities
• Modem control applications utilizing standard handshake signals

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'NR' indicates tape-and-reel packaging when sourcing this component. Confirm the 'G4' designation aligns with current lead-free manufacturing standards. Check official Texas Instruments channels for active production status as older variants may be discontinued.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this variant for applications requiring surface-mount assembly in a compact 44-pin PLCC footprint. Ensure the system design supports the required 3.3 V or 5 V logic levels. Verify that the operating temperature range meets the commercial specifications of the device.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the TL16C550C family of asynchronous communications elements. It serves as a functional upgrade to the TL16C550B and provides enhanced performance over the legacy TL16C450 through integrated FIFO buffering and advanced flow control mechanisms.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C550CI is functionally equivalent but may differ in package type. Direct pin-compatible replacements include other members of the TL16C550 series, provided the specific package and voltage requirements match the application design.
