XR16V2652IL

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2652IL is a dual universal asynchronous receiver/transmitter (DUART) integrated circuit manufactured by Sipex. It integrates two independent RS-232 transmitters and receivers on a single chip, designed for applications requiring multiple serial communication ports in space-constrained environments. The device operates with a single supply voltage ranging from 3.0 V to 5.5 V, ensuring compatibility with low-voltage logic systems. Each channel supports data rates up to 2.5 Mbps, facilitating high-speed serial communication. The IC features full hardware flow control, including RTS/CTS and DTR/DSR signals, to manage data transmission efficiently. It is housed in a compact 24-pin TSSOP package, which aids in miniaturization of electronic designs while maintaining robust performance standards for industrial and commercial use.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation as Sipex or its successor entities, as corporate acquisitions may affect branding. Confirm the specific package variant matches the 24-pin TSSOP form factor required for your PCB layout. Ensure the operating voltage range aligns with your system's power supply specifications. Check for any updated lead times or availability status directly through authorized distributors. Validate that the component meets the necessary environmental and safety certifications for your target market.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires two separate RS-232 channels but has strict space limitations. It is suitable for systems operating between 3.0 V and 5.5 V where low power consumption is beneficial. Consider this part if hardware flow control is essential for preventing data loss at high baud rates. Compare it against single-channel alternatives if only one port is needed to optimize cost. Ensure the thermal characteristics of the TSSOP package are adequate for the expected ambient temperature conditions.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16V2652IL belongs to the broader family of dual UART controllers designed for serial communication tasks. It complements single-channel variants like the XR16V2650 by offering doubled interface density. This series is commonly used in legacy system upgrades and new embedded designs requiring standard RS-232 signaling. Its architecture allows for straightforward integration into microcontroller-based systems, serving as a bridge between digital logic and serial peripheral devices.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-compatible replacements from manufacturers such as MaxLinear or Exar, which may have acquired related product lines. Verify that any substitute maintains the same 24-pin TSSOP footprint and electrical specifications. Ensure the alternative device supports the required 2.5 Mbps data rate and voltage range. Confirm that flow control signal mappings remain identical to avoid PCB redesign.
