XR16L570IL32-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L570IL32-F is a single-channel UART interface integrated circuit manufactured by MaxLinear. It features a 16-byte transmit and receive FIFO buffer to enhance data throughput efficiency. The device supports high-speed serial communication with a maximum data rate of 4 Mb/s. It operates within a supply voltage range of 1.62 V to 5.5 V, accommodating various logic levels including 1.8 V, 2.5 V, 3.3 V, and 5 V systems. The component is housed in a QFN-24 surface-mount package and is rated for an operating temperature range from -40°C to +85°C. Typical operating current is specified at 3 mA.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Integrates a 16-byte deep FIFO buffer for both transmission and reception to minimize CPU intervention.
• Supports multiple serial protocol standards including IrDA, RS-232, RS-422, and RS-485 interfaces.
• Includes a power save mode capability to reduce energy consumption during low activity periods.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation control systems requiring robust serial communication.
• Embedded devices utilizing IrDA or standard RS-232/422/485 links.
• Portable electronics powered by varying voltage rails (1.62V to 5.5V).

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the exact suffix against official MaxLinear documentation, as the provided input model XR16L570IL32-F differs from the verified datasheet entry XR16L570IL24TR-F. Confirm pinout compatibility and package type (QFN-24 vs QFN-32) before procurement. Check for end-of-life status and availability constraints through authorized distributors.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with moderate speed (up to 4 Mb/s) and small footprint is required. Ensure the application voltage aligns with the 1.62 V to 5.5 V operational range. Consider the QFN-24 package constraints for PCB layout. Verify if the 16-byte FIFO depth meets the system's burst data handling requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the MaxLinear XR16L5xx series of low-power UART controllers. It shares functional similarities with other members like the XR16L580 but offers a single channel configuration. The series is designed for applications needing flexible interface support and low power consumption in compact packages.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes may include other single-channel UARTs from the same family, such as the XR16L580IM-F, though package differences (TQFP-48 vs QFN-24) require mechanical adaptation. Cross-reference electrical specifications carefully.
