XR16V2550IM-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16V2550IM-F is a dual UART interface integrated circuit manufactured by MaxLinear. It features two independent DUART channels with 16-byte transmit and receive FIFOs, supporting data rates up to 4 Mbps. The device operates on a single supply voltage ranging from 2.25 V to 3.6 V. It includes an internal oscillator, IrDA encoder/decoder, automatic flow control, and modem control signals. Packaged in a 48-TQFP surface-mount format, it supports RS-232, RS-422, and RS-485 protocols within an operating temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual independent UART channels with 16-byte FIFO buffers for efficient data handling
• Integrated IrDA encoder and decoder for infrared communication compliance
• Supports automatic hardware flow control and full modem control signal interfacing

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication
• Embedded devices needing multiple asynchronous serial ports
• Infrared data exchange modules utilizing IrDA protocols

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'IM-F' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Check for any recent product discontinuation notices or lifecycle changes from MaxLinear before finalizing procurement plans. Ensure the 48-TQFP package dimensions match your PCB footprint requirements precisely.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with moderate speed (4 Mbps) and IrDA support is required. It is suitable for applications needing operation between 2.25 V and 3.6 V. Consider alternative models if higher data rates or larger FIFO depths are necessary, as this part is optimized for standard industrial serial interfaces rather than high-throughput networking.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the MaxLinear XR16V2550 series of dual UART controllers. It is functionally similar to other parts in the XR16L2550 family but may differ in voltage specifications or packaging options. The IM suffix typically denotes a specific temperature grade and package type within the MaxLinear portfolio.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The XR16L2550IM-F is a potential substitute with similar dual UART and FIFO characteristics. Verify voltage ranges and protocol support compatibility before substitution. Other MaxLinear VLIO UARTs may offer different FIFO sizes or speeds.
