SC16C2550BIA44,518

Overview

The SC16C2550BIA44,518 is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP Semiconductors. It operates at supply voltages of 5 V, 3.3 V, and 2.5 V within the industrial temperature range (-40 °C to +85 °C). The device supports serial data rates up to 5 Mbit/s at 5 V and 3.3 V, and up to 3 Mbit/s at 2.5 V. It features 16-byte transmit and receive FIFOs with selectable interrupt trigger levels. The component is housed in a PLCC44 package.

Feature Summary

Dual independent UART channels with 16-byte FIFOs for reduced CPU bandwidth requirements
Software compatible with industry standards including INS8250 and SC16C550
Supports DMA mode data transfer controlled by FIFO trigger levels and ready signals
Includes internal loopback capability for on-board diagnostics

Applications

High-speed modem applications requiring fast data processing
Shared network environments needing efficient serial communication
Industrial systems operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and revision level. Confirm that the PLCC44 package variant matches the target PCB footprint requirements. Check for any updated environmental compliance declarations or lead-free status changes relative to the original datasheet specifications.

Selection Notes

Select this component when a dual-channel UART solution with integrated FIFOs is required for parallel-to-serial conversion. Ensure the system design accommodates the PLCC44 package dimensions. Verify that the external clock source meets the frequency requirements for the desired baud rate generation capabilities.

Part Context

This part belongs to the SC16C2550B family of dual UART interface ICs. It serves as an enhanced successor to the 16C2450, providing additional FIFO memory and DMA support while maintaining pin compatibility. The family includes variants in LQFP48, DIP40, and HVQFN32 packages to suit different board space constraints.
