UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Data communication systems requiring serial connectivity
• Industrial control equipment needing reliable serial interfaces
• Portable consumer electronics utilizing low-power serial protocols

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation carefully, as Sipex has been acquired by MaxLinear, and parts may be labeled under EXAR or MaxLinear branding. Confirm the specific package type, such as 32-VFQFN, matches your PCB footprint requirements. Ensure the voltage specifications align with your system's power rails, particularly noting the 2.25V to 3.6V operating range and 5V input tolerance. Cross-reference the datasheet to confirm pinout compatibility if substituting from previous generations.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual-channel serial communication is required in space-constrained designs. The integrated FIFOs reduce processor load compared to standard UARTs without buffers. Consider the 32-VFQFN package for surface-mount assembly needs. Verify that the 5V-tolerant inputs meet the signal levels of connected microcontrollers or legacy peripherals. This part is suitable for applications balancing performance with low power consumption constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16V2650IL belongs to the V265x series of dual UARTs from Sipex, now part of MaxLinear. These components are designed for embedded systems requiring robust serial communication. The series typically offers varying FIFO depths and package options. The IL suffix generally indicates a specific temperature range and package variant, commonly found in industrial and commercial applications where reliable serial data transfer is critical for system operation.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for XR16V2650IL-F variants which may offer different packaging or lead-free compliance. Verify cross-compatibility with other V265x series parts like XR16V2652 if pinout and electrical characteristics match. Confirm that any substitute maintains the 32-byte FIFO structure and 5V input tolerance to ensure functional equivalence in existing designs.
