UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR-F' indicates tape-and-reel packaging configuration distinct from tray variants. Confirm end-of-life status and availability of alternative sources due to discontinuation notices. Ensure compatibility with existing PCB footprints for 68-pin PLCC packages during replacement planning. Validate regulatory compliance documentation for current manufacturing batches.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with moderate FIFO depth is required in a compact PLCC package. Consider the 2.97V to 5.5V operating range for flexibility in power supply design. Evaluate the 4 Mb/s maximum data rate against application bandwidth needs. Assess the availability of substitutes if production volume requires long-term supply assurance.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the ST16C55x series of UART interface ICs from MaxLinear, previously associated with Exar. The series is known for providing robust serial communication solutions with FIFO capabilities. The ST16C552 variant specifically offers dual channels, distinguishing it from single-channel or quad-channel counterparts in the same family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

ST16C552IJ68-F is a pin-compatible tray version of the same functional device. TL16C552AFN is listed as a similar substitute by other manufacturers, though package and electrical specifics should be verified.
