UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'TR-F' indicates tape and reel packaging when sourcing components. Confirm that the manufacturer designation aligns with MaxLinear or its predecessor entities such as Exar, as part numbers may reflect corporate transitions. Ensure the operating temperature range and voltage specifications match the target application requirements before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with IrDA capability is required. The 16-byte FIFO depth provides adequate buffering for moderate throughput applications up to 1.5Mbps. Consider the 48-TQFP package size for PCB layout constraints. This part is suitable for systems needing hardware flow control without external logic gates.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This UART controller belongs to the ST16CxxxC series of high-performance serial interface ICs. It is designed to replace legacy UART components while offering enhanced features like IrDA support and larger FIFO buffers. The integration of a timer/counter reduces the need for external timing components, simplifying system design and reducing overall bill of materials cost.
