UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status and check for end-of-life notices or production changes. Ensure the specific suffix matches the required packaging format. Validate electrical specifications against current design requirements before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when designing systems requiring four simultaneous UART ports with moderate speed capabilities. Consider the 1.62V to 3.63V operating range for low-voltage applications. Evaluate the 64-LQFP package constraints for PCB layout. Compare against higher-speed alternatives if data rates exceed 16 Mbps are necessary.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16M series of UART interface ICs from MaxLinear. It is functionally similar to other quad-channel UARTs but distinguished by its specific voltage range and FIFO depth. It serves as a bridge between microprocessors and serial peripheral devices.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-to-pin replacements within the XR16M series. Verify compatibility of FIFO sizes and voltage ranges. Consult manufacturer documentation for approved substitute part numbers.
