Overview
The SC16C2550IA44,529 is a dual Universal Asynchronous Receiver/Transmitter (UART) manufactured by NXP USA Inc. It features two independent UART channels with 16-byte transmit and receive FIFOs and an integrated infrared encoder/decoder. The device supports data rates up to 5 Mbits/s at 5 V and 3.3 V, and 3 Mbits/s at 2.5 V. It operates within the industrial temperature range (-40°C to +85°C). The component is housed in a PLCC44 package and provides hardware/software flow control, DMA mode support, and programmable baud rate generation.
Feature Summary
- Dual-channel architecture with 16-byte FIFOs for both transmission and reception
- Integrated infrared (IrDA) encoder and decoder functionality
- Support for automatic hardware and software flow control mechanisms
- Programmable baud rate generator supporting high-speed modem technologies
Applications
- High-speed serial communication interfaces requiring FIFO buffering
- Infrared data exchange systems utilizing IrDA protocols
- Industrial embedded controllers operating in wide temperature environments
- Multi-channel asynchronous data acquisition and processing units
Procurement Notes
Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary industrial temperature specifications for the intended application environment. Ensure compatibility with existing system voltage levels before integration.
Selection Notes
Select this component when dual independent UART channels are required alongside infrared capabilities. Consider the PLCC44 package constraints for PCB layout. Evaluate the need for 16-byte FIFO depth versus simpler buffer requirements to optimize system performance and CPU load.
Part Context
This part belongs to the SC16C2550 family of dual UARTs. It is functionally compatible with the ST16C2550 and power-ups as equivalent to the 16C2450. The IA44 designation specifically identifies the plastic leaded chip carrier package version within the broader product line.
Replacement Considerations
The SC16C2550IA44 is pin-compatible with the ST16C2550. Verify software compatibility with legacy 16C2450 designs if migrating from older components. Check for updated datasheet revisions to ensure feature parity.
