SC16C2552BIA44,529

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C2552BIA44,529 is a dual Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP USA Inc. It operates at 5 V, 3.3 V, and 2.5 V with an industrial temperature range of −40 °C to +85 °C. The device supports data rates up to 5 Mbit/s at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V. It features 16-byte transmit and receive FIFOs, independent baud rate generators, and DMA operation via TXRDY/RXRDY signals. Packaged in PLCC44 (SOT187-2), it provides pin-to-pin compatibility with PC16C552 and ST16C2552.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix ',529' against official NXP documentation to confirm tape and reel packaging or specific variant details. Ensure the PLCC44 package type matches the design requirements. Confirm that the industrial temperature range and voltage specifications align with the target system environment before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual UART interface with 16-byte FIFOs is required for systems operating at 5 V, 3.3 V, or 2.5 V. It is suitable for applications needing high data rates up to 5 Mbit/s and DMA support. Verify compatibility with existing designs using PC16C552 or ST16C2552 due to pin-to-pin equivalence.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C2552B series includes variants such as SC16C2552BIA44-T and SC16C2552BIA44. These devices are part of NXP's enhanced UART family, offering improved performance over older generations like the 16C450. The SC16C2552B provides concurrent register writes and internal loopback capabilities for diagnostics.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Pin-to-pin compatible with PC16C552 and ST16C2552. Consider XR16L2552 for lower voltage operation down to 2.25 V.
