XR16C2850CMTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C2850CMTR-F is a dual Universal Asynchronous Receiver/Transmitter (UART) integrated circuit manufactured by MaxLinear. It features two independent channels with 128-byte transmit and receive FIFOs, supporting data rates up to 6.25 Mbps. The device operates on a supply voltage range of 2.97 V to 5.5 V and is housed in a 48-TQFP surface-mount package. Key interface protocols include RS-232 and RS-485, with built-in hardware flow control and IrDA encoding/decoding capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'CMTR-F' against official MaxLinear documentation to confirm tape-and-reel packaging and exact electrical characteristics. Cross-reference the manufacturer part number with current datasheets to ensure compatibility with existing designs, as component revisions may affect pinout or performance specifications without explicit notice.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual-channel asynchronous communication with substantial buffering is required. The 128-byte FIFO reduces processor overhead compared to standard UARTs. Ensure the design supports the 48-TQFP package dimensions and that the operating voltage aligns with the 2.97 V to 5.5 V range. Verify thermal requirements for the TQFP enclosure in enclosed applications.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C2850 series of dual UART interfaces. It shares functional similarities with the XR16C2850CM but differs in packaging format, indicated by the 'TR' suffix denoting tape and reel delivery. It serves as a serial interface solution within the broader MaxLinear portfolio of communication ICs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct substitutes include the XR16C2850CM for tray-packaged equivalents. Check for pin-compatible alternatives from other manufacturers if the MaxLinear source is unavailable, ensuring FIFO depth and speed ratings match the original design requirements.
