UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's current documentation to confirm lead time and availability status. Ensure the 48-TQFP package matches your PCB footprint requirements. Confirm that the 2.25V to 5.5V operating range aligns with your system power design. Check for any recent lifecycle changes or obsolescence notices from MaxLinear before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels are required with hardware flow control support via FIFOs. It is suitable for applications demanding 5-volt tolerance on input pins while operating at lower core voltages. Consider the 48-TQFP package constraints for board space. Verify that the 3.125 Mbps maximum data rate meets the throughput requirements of the target serial devices.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the MaxLinear XR16L series of UART interface controllers. It is functionally similar to other industry-standard DUARTs but offers specific integration of FIFOs and timers. The IM-F suffix indicates the package type and environmental compliance. It serves as a bridge between parallel microprocessor buses and serial communication lines.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Cross-reference with XR16L2550IM-F for single-channel applications or XR16L2551IL-F if QFN packaging is preferred. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement part supports the same 16-byte FIFO depth and 5-volt tolerant input characteristics.
