UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific revision date code on the component marking, as enhanced features such as 5V tolerant inputs and 0 ns address hold time are available only in devices with a top mark date code of F2 YYWW and newer. Confirm package compatibility and pin assignments against the target design specifications before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component for designs requiring dual UART interfaces with high-speed FIFO buffering. Ensure the system voltage aligns with the 2.97 V to 5.5 V operating range. Verify that the required data rate does not exceed 3 Mbps at 5 V or 2 Mbps at 3.3 V. Check if the specific revision provides necessary timing characteristics like 0 ns address hold time.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context
