UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized MaxLinear distributors or certified partners. Confirm the specific suffix 'IV-F' matches project requirements regarding package type and temperature grade. Request official datasheets and RoHS compliance documentation prior to ordering. Ensure storage conditions adhere to moisture sensitivity levels specified in the manufacturing data sheet to prevent package damage during assembly.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required with substantial buffering capacity. The 64-byte FIFO reduces CPU overhead compared to smaller buffer alternatives. Verify that the 2.97 V to 5.5 V input range aligns with the system power rails. Consider the 64-LQFP footprint for PCB layout constraints. Evaluate thermal performance within the -45°C to +85°C operational envelope for environmental suitability.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the MaxLinear VLIO series of UART interface controllers. It complements other models like the XR16V654IL-F which offers similar functionality but in a QFN-48 package. The series focuses on providing robust serial communication solutions for embedded applications.
