TL16C554AIPNG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C554AIPNG4 is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Texas Instruments. It features four independent UART channels, each equipped with a 16-byte FIFO to enhance data throughput and reduce processor intervention. The device supports data rates up to 1 Mbps and operates within a supply voltage range of 3V to 5.25V. It is housed in an 80-LQFP package measuring 12x12 mm. Key functional attributes include automatic flow control, modem control signals, and false start bit detection capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free and RoHS compliance status. Confirm the specific package variant matches the required PCB footprint. Ensure the operating voltage range aligns with the target system's power supply rails. Check for any specific environmental or export classification requirements relevant to the deployment region.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple independent UART channels are required in a single package. The 16-byte FIFOs make it suitable for applications with bursty data traffic. Ensure the host system can support the 80-pin LQFP package size. Verify that the 1 Mbps maximum data rate meets the application's speed requirements compared to lower-speed alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the TL16C554 family of asynchronous communication elements. The 'A' designation typically indicates an enhanced version with additional features like auto-flow control compared to earlier iterations. The 'G4' suffix denotes a lead-free, RoHS-compliant manufacturing variant. It serves as a multi-channel interface solution for microcontrollers and DSPs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C554AIPN is listed as a parameter-equivalent alternative. Verify pin compatibility and electrical specifications before substitution. Other family members may lack the specific FIFO depth or control features.
