XR68M752IM48-F

Overview

The XR68M752IM48-F is a dual-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 1.62 V to 3.63 V and supports data rates up to 16 Mb/s. The device features 64-byte transmit and receive FIFOs for each channel. It is housed in a QFN-32 package and is designed for surface-mount installation. The component functions across an industrial temperature range from -40°C to +85°C, with a typical operating current of 2 mA.

Feature Summary

• Dual independent UART channels with dedicated 64-byte TX and RX FIFOs
• Wide supply voltage compatibility supporting 1.62 V to 3.63 V operation
• High-speed asynchronous serial communication capability up to 16 Mb/s
• Industrial-grade thermal performance rated for -40°C to +85°C environments

Applications

• Industrial automation control systems requiring high-speed serial connectivity
• Embedded computing platforms needing multiple asynchronous serial ports
• Telecommunications equipment utilizing low-voltage logic interfaces
• Test and measurement devices demanding precise timing and data throughput

Procurement Notes

Verify the specific suffix 'F' against official MaxLinear documentation to confirm RoHS compliance status and lead-free manufacturing specifications. Confirm that the QFN-32 package dimensions match your PCB footprint requirements exactly. Check for any recent Product Change Notices (PCNs) regarding material or process updates. Ensure the supplier provides valid traceability documents for this discontinued or limited-stock item.

Selection Notes

Select this component when dual-channel asynchronous communication is required with high data throughput capabilities. The wide input voltage range allows flexibility in system power design without external level shifting. Consider the QFN-32 package size constraints during layout planning. Verify that the 64-byte FIFO depth meets your buffer requirements for burst data transmission scenarios.

Part Context

This part belongs to the XR68M series of UART interface controllers from MaxLinear. It serves as a bridge between parallel processor buses and serial asynchronous lines. The dual-channel architecture distinguishes it from single-port variants in the same family. It is intended for applications requiring reliable serial data exchange in compact form factors.
