XR16C2850CJ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C2850CJ-F is a dual universal asynchronous receiver and transmitter (DUART) serial I/O controller manufactured by MaxLinear. It features two independent channels, each equipped with a 128-byte transmit and receive FIFO buffer to enhance throughput and reduce CPU overhead. The device supports data rates up to 6.25 Mbps and operates on a single supply voltage ranging from 2.97 V to 5.5 V. It is housed in a 44-pin Plastic Quad Flat Package (PLCC). Key functional blocks include baud rate generators, modem control logic, and IrDA encoding/decoding capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual-channel architecture with independent 128-byte FIFOs for high-speed data buffering
• Integrated IrDA encoder and decoder supporting infrared communication protocols
• Comprehensive hardware flow control and modem status signal management

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial automation systems requiring reliable serial communication
• Telecommunications equipment utilizing RS-232 or RS-485 interfaces
• Embedded computing platforms needing multiple UART ports

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm package type and temperature range. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for obsolescence notices or lifecycle changes prior to finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with deep FIFO buffers is required. Ensure the system design accommodates the PLCC-44 footprint. Verify that the operating voltage range aligns with the target power supply rails and that the maximum data rate meets application timing requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the XR16C2850 family of DUART controllers. It shares architectural similarities with other Exar/MaxLinear UARTs but is distinguished by its specific 128-byte FIFO depth and 44-pin PLCC packaging configuration. It serves as a direct replacement for legacy dual UART solutions in existing designs.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Cross-reference with XR16C2850CM-F for TQFP package alternatives. Verify pin compatibility if substituting with other members of the XR16C2850 series. Consult manufacturer PCNs for any functional changes in newer production lots.
