XR16C2850CM-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C2850CM-F is a dual universal asynchronous receiver and transmitter (DUART) integrated circuit manufactured by MaxLinear, Inc. It features two independent channels with 128-byte transmit and receive FIFOs to enhance data throughput. The device supports RS-232 and RS-485 communication protocols and includes an internal oscillator. Key electrical specifications include a maximum data rate of 6.25 Mbps, a supply voltage range of 2.97 V to 5.5 V, and automatic flow control capabilities. It is housed in a 48-TQFP package measuring 7x7 mm.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual channel architecture supporting independent serial communication paths
• Integrated 128-byte FIFO buffers for both transmission and reception
• Internal oscillator eliminates the need for external clock components
• Supports IrDA encoding/decoding and false start bit detection

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial connectivity
• Embedded controllers needing multiple UART interfaces
• Point-of-sale terminals utilizing RS-232 or RS-485 standards
• Medical equipment with strict serial communication requirements

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be marked as obsolete in some catalogs. Ensure packaging integrity matches the 48-TQFP specification during receipt inspection.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality is required within a single package footprint. Compare against single-channel alternatives if only one interface is needed to optimize board space. Verify that the 6.25 Mbps maximum speed meets system timing requirements and that the 2.97 V to 5.5 V operating voltage aligns with the target power supply design.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This device belongs to the XR16C2850 series of UART controllers. It shares functional similarities with other MaxLinear serial interface ICs but is distinct due to its dual-channel configuration and specific FIFO depth. The CM suffix indicates the commercial temperature range and TQFP package variant.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Check for pin-compatible upgrades within the MaxLinear portfolio. Verify that any substitute maintains the 128-byte FIFO size and 48-TQFP package dimensions. Ensure protocol support for RS-232 and RS-485 remains consistent across potential replacement parts.
