UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific manufacturer designation as listings may attribute this part to MaxLinear or its predecessor entities. Confirm the exact suffix and package type against official datasheets before integration. Check for end-of-life status or alternative sourcing options due to potential discontinuation indicated in distributor records.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART interfaces in a single footprint. Ensure the application environment stays within the specified -40°C to +85°C temperature limits. Verify that the system power supply aligns with the 2.97 V to 5.5 V operational range and that the 100-pin PQFP package fits the PCB layout constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C654 series of UART interface ICs. It shares functional similarities with other quad-channel UARTs like the XR16C864 but differs in specific pinout and feature sets. The ST16C654 is distinct from dual-channel variants such as the XR16C2850, offering higher channel density for complex serial networking tasks.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with the XR16C864IQTR-F only if pin compatibility and protocol support are verified through official documentation.
