Overview
The SC16C2550IA44,512 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 and utilizes a PLCC44 package.
Feature Summary
- Dual-channel architecture with 16-byte FIFOs for both transmission and reception
- Integrated infrared (IrDA) encoder and decoder functionality
- Support for hardware and software flow control mechanisms
- Programmable baud rate generator supporting internal or external clock sources
Applications
- High-speed modem interfaces
- Shared network environments requiring fast data processing
- Industrial communication systems operating in wide temperature ranges
Procurement Notes
Verify the specific ordering suffix IA44,512 against current NXP documentation to confirm package type and manufacturing status. Ensure compatibility with existing system voltage levels of 5 V, 3.3 V, or 2.5 V. Confirm that the PLCC44 package footprint matches the target PCB design requirements.
Selection Notes
Select this component when dual serial ports with FIFO buffering are required. It serves as a pin-compatible upgrade to the ST16C2550 and offers enhanced performance over the 16C2450. Consider the IrDA capability if infrared communication is necessary. Verify software compatibility with legacy 16C2450 designs if migrating from older architectures.
Part Context
This part belongs to the SC16C2550 family of dual UARTs. It is functionally equivalent to the ST16C2550 and provides enhanced features compared to the single-FIFO 16C2450. The device is designed for applications needing reliable serial data conversion with reduced CPU overhead due to FIFO buffering.
Replacement Considerations
The SC16C2550IA44 is pin-compatible with the ST16C2550. It can replace the 16C2450 in designs requiring FIFO support, provided software adjustments are made for the enhanced features.
