XR16V2552IL-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2552IL-F is a dual universal asynchronous receiver and transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features two independent UART channels, each equipped with a 16-byte transmit and receive FIFO buffer to enhance data throughput and reduce processor overhead. The device supports high-speed serial communication with a maximum data rate of 16 Mb/s. It operates within a supply voltage range of 2.25 V to 3.6 V, compatible with standard 2.5 V, 3.3 V, and 5 V logic levels. The component is housed in a compact QFN-32 surface-mount package and is rated for industrial operating temperatures from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent UART channels with dedicated 16-byte FIFO buffers for efficient data handling.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix and manufacturer designation carefully, as Exar was acquired by MaxLinear. Confirm RoHS compliance status through official documentation. Check for end-of-life notifications or discontinuation notices prior to procurement planning. Ensure the QFN-32 package footprint matches the target PCB design constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual-channel UART solution with moderate FIFO depth is required. Verify that the 16 Mb/s data rate meets system timing requirements. Ensure the 2.25 V to 3.6 V supply voltage aligns with the target power domain. Consider the QFN-32 package size relative to available board space and thermal dissipation capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context
