XR16M2651IL32

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M2651IL32 is a quad universal asynchronous receiver/transmitter (QUART) manufactured by Sipex. It integrates four independent UART channels on a single chip, designed for high-density serial communication applications. The device operates within a supply voltage range of 3.0V to 3.6V and supports data rates up to 3 Mbps. It features a 32-pin LQFP package with an industrial temperature range specification. Key electrical characteristics include low power consumption and compatibility with standard RS-232 and RS-485 interfaces when paired with external transceivers.

• Medical devices requiring reliable serial communication links

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer designation as Sipex or its successor entities, as corporate acquisitions may affect part sourcing. Confirm the specific suffix IL32 corresponds to the 32-pin LQFP package and industrial temperature grade. Request official datasheets to validate pinout configurations and electrical specifications against current production standards before procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART interfaces are required in a space-constrained design. Ensure the operating environment falls within the specified industrial temperature range. Verify that the 3.0V to 3.6V supply voltage aligns with the system power architecture. Consider external transceiver requirements if interfacing with RS-232 or RS-485 physical layers.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16M2651 series belongs to Sipex's QUART family of multi-channel UART controllers. These components are engineered to replace multiple single-channel UARTs, reducing board space and assembly complexity. The IL32 variant specifically denotes the lead-free, industrial-grade version in a 32-lead plastic quad flat package without leads.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct cross-references from manufacturers like MaxLinear or Exar, which have acquired related asset lines. Verify pin-to-pin compatibility and register-level software compatibility before substituting. Ensure the replacement part maintains the same 32-pin LQFP footprint and industrial temperature rating.
