UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IQ' against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications. Confirm current availability status as distribution channels may list this component as end-of-life or limited stock. Ensure the source document matches the exact part number before procurement to avoid functional mismatches in design integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires four distinct UART interfaces within a single integrated circuit. Verify that the system voltage falls within the 2.97 V to 5.5 V range. Ensure the PCB layout accommodates the PQFP-100 package dimensions. Consider the 2 Mb/s maximum data rate against application requirements. Check if the 128-byte FIFO depth meets buffer needs for high-throughput serial transfers.
