SC16C2550BIA44,512

Overview

The SC16C2550BIA44,512 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 with an industrial temperature range. The device features 16-byte transmit and receive FIFOs to reduce CPU bandwidth requirements. It supports data rates up to 5 Mbit/s at 5 V and 3.3 V, and up to 3 Mbit/s at 2.5 V. The component is housed in a PLCC44 package.

Feature Summary

Dual independent UART channels with 16-byte FIFOs for both transmission and reception
Supports high-speed serial communication up to 5 Mbit/s
Compatible with standard 16C2450 pinout and software interfaces
Includes internal loopback capability for on-board diagnostics

Applications

Portable appliances requiring serial connectivity
Telecommunication network routers
Factory automation and process control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and tape-and-reel specifications. Confirm that the PLCC44 variant matches the target PCB footprint and lead configuration requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual UART interface with integrated FIFOs is required for applications needing reduced CPU interrupt overhead. Ensure the system design accommodates the PLCC44 package dimensions and that the operating voltage aligns with the 5 V, 3.3 V, or 2.5 V capabilities specified in the datasheet.

Part Context

This part belongs to the SC16C2550B family of dual UARTs from NXP Semiconductors. It serves as an enhanced successor to the 16C2450, offering increased performance through built-in FIFO memory. The IA44 designation specifically identifies the plastic leaded chip carrier package variant within this product line.
