UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C2550IJ-F is a dual universal asynchronous receiver and transmitter (UART) fabricated in an advanced CMOS process. It operates from a 2.97V to 5.5V power supply with 5V tolerant inputs. The device integrates two independent UART channels, each featuring 16-byte transmit and receive FIFOs. Data rates reach up to 4 Mbps with a 64 MHz external clock or 1.5 Mbps with a 24 MHz crystal. It is housed in a 44-pin PLCC package and supports an operating temperature range of -40°C to +85°C.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's official documentation to confirm compliance details such as RoHS status and lead-free specifications. Confirm that the 44-lead PLCC package matches the design requirements. Ensure the operating temperature range aligns with the intended environmental conditions before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual-channel serial interface is required with integrated buffering to reduce CPU overhead. It serves as a pin-compatible upgrade to the ST16C2450 and is compatible with the TL16C752B on the TQFP package. Consider the 44-pin PLCC form factor for board layout constraints. Verify clock source availability for the desired baud rate generation.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The XR16C2550 is part of the Exar/MaxLinear UART family, representing an enhanced version of the standard 16C550 architecture. It improves upon previous generations by adding 16-byte FIFOs to both transmit and receive paths. This integration allows for higher throughput and reduced interrupt servicing times compared to non-FIFO counterparts like the ST16C2450.
