Overview
The XR68M752IL32TR-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 efficient data handling. It is housed in a QFN-32 package suitable for surface mount technology. 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 UART channels providing independent asynchronous serial communication capabilities
- Integrated 64-byte transmit and receive FIFOs to manage data flow efficiently
- Supports high-speed data transmission rates up to 16 Mb/s
- Operates on low voltage supplies ranging from 1.62 V to 3.63 V
Applications
- Industrial automation systems requiring reliable serial communication
- Embedded control units needing multiple UART interfaces
- Telecommunications equipment utilizing asynchronous data transfer
- Consumer electronics with low-power serial port requirements
Procurement Notes
Verify the specific suffix TR-F indicates tape and reel packaging when sourcing this component. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the QFN-32 footprint matches your PCB design constraints. Check for any product change notices or lifecycle updates that may affect long-term availability.
Selection Notes
Select this model when dual UART functionality is required in a compact surface-mount package. Consider the 1.62 V to 3.63 V operating range for compatibility with low-voltage logic levels. The 64-byte FIFO depth is suitable for applications demanding moderate buffer sizes without external memory. Verify thermal performance within the -40°C to +85°C range for your specific environment.
Part Context
This part belongs to the XR68M752 series of UART interface ICs from MaxLinear. It shares core specifications with the XR16M752IL32-F but differs in packaging format, with the TR-F suffix denoting tape and reel delivery. Both variants offer dual-channel operation and similar electrical characteristics for serial communication tasks.
Replacement Considerations
The XR16M752IL32-F is a documented substitute offering identical functional specifications. Verify that the QFN-32 package dimensions are compatible with your existing board layout. Ensure the replacement meets the same voltage and temperature requirements for seamless integration.
