XR16V564IL

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V564IL is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by MaxLinear, formerly Sipex. It provides four independent UART channels within a single package, supporting data rates up to 3 Mbps. The device operates with a supply voltage range of 3.0 V to 5.5 V and features low power consumption. It includes full hardware flow control, programmable baud rate generators, and interrupt capabilities. The component is housed in a 28-pin SOIC package and is designed for applications requiring multiple serial communication interfaces.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates four independent UART channels for multi-port serial communication
• Supports high-speed data transmission up to 3 Mbps
• Includes full hardware flow control signals (RTS/CTS, DTR/DSR)
• Operates on a single 3.0 V to 5.5 V power supply

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial connections
• Telecommunications equipment with multi-port interface needs
• Embedded systems with limited board space for serial I/O
• Point-of-sale terminals and payment systems

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the manufacturer status as MaxLinear acquired the Sipex product line. Confirm the specific suffix 'IL' indicates the 28-pin SOIC package and industrial temperature range. Check for end-of-life notifications or discontinuation notices from the current manufacturer before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART interfaces are required in a compact form factor. Ensure the system voltage aligns with the 3.0 V to 5.5 V operating range. Consider the 3 Mbps maximum baud rate against application requirements. Verify that the 28-pin SOIC package fits the PCB layout constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V564 series of quad UARTs. It shares functional similarities with other members of the family but differs in package type and temperature rating based on its suffix. The series is known for providing multiple serial ports in a single IC, reducing board space compared to using individual UART chips.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for direct pin-to-pin replacements within the XR16V564 series from MaxLinear. Verify compatibility with alternative quad UARTs from other manufacturers if sourcing is difficult. Ensure electrical parameters such as voltage range and data rates match the original design specifications.
