XR16V2552IJ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2552IJ-F is a dual-channel UART interface integrated circuit manufactured by MaxLinear. It features two independent UART channels with 16-byte transmit and receive FIFOs, supporting data rates up to 16 Mb/s. The device operates on supply voltages of 2.5 V, 3.3 V, or 5 V, with a minimum operating voltage of 2.25 V and a maximum of 3.6 V. It is housed in a QFN-32 package and functions within an industrial temperature range from -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent UART channels for simultaneous serial communication
• Integrated 16-byte FIFO buffers for both transmission and reception
• Support for high-speed data transfer rates up to 16 Mb/s
• Compatibility with standard Intel and Motorola bus interfaces

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring multiple serial ports
• Embedded control units with limited I/O pin availability
• Telecommunications equipment utilizing RS-232 or RS-422/485 signaling
• Medical devices needing reliable serial data exchange

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IJ' against official MaxLinear documentation to confirm package type and temperature grade. Confirm current production status as some variants may be discontinued. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality is required in a compact form factor. Compare FIFO depth requirements against other models like the XR16V2554 if more channels are needed. Verify voltage compatibility with the target system logic levels before integration.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16V255x family of VLIO UARTs. It shares architectural similarities with single-channel (XR16V2550) and quad-channel (XR16V2554) variants. The family is designed for low-power, high-performance serial communication applications in embedded environments.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16V2552IMTR-F for tape-and-reel packaging. For quad-channel needs, consider the XR16V2554IL-F. Verify pinout compatibility and electrical specifications before swapping with older Exar-branded equivalents.
