UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against official MaxLinear documentation to confirm packaging and environmental compliance details. Ensure the 48-pin TQFP footprint matches the target PCB design. Confirm that the commercial temperature range (-40°C to 85°C) meets system requirements. Cross-reference the manufacturer part number with current distributor listings to validate availability status.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual-channel UART solution with moderate FIFO depth is required. The 2.97V to 5.5V input range allows flexibility in power supply design. Consider the 48-pin TQFP package constraints during layout planning. Verify that the 4 Mbps maximum speed aligns with the application's throughput needs without requiring higher-performance alternatives.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C2550 series of VLIO UARTs from MaxLinear. It is functionally related to other variants such as the ST16C2550IQ48-F and ST16C2550IP40, differing primarily in package type and temperature rating. The series provides a standardized interface for legacy and modern serial communication protocols.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-compatible replacements within the same MaxLinear family. Evaluate cross-manufacturer equivalents like the TL16C550DIPTG4 for similar functionality. Verify electrical parameter compatibility before substitution.
