SC16C2552BIA44,512

Overview

The SC16C2552BIA44,512 is a dual-channel 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 features 16-byte transmit and receive FIFOs, supporting data rates up to 5 Mbit/s at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V. It includes independent programmable baud rate generators, modem control interfaces, DMA operation capabilities, and concurrent register writes for both channels.

Feature Summary

Dual UART channels with 16-byte FIFOs for enhanced data throughput
Supports 5 V, 3.3 V, and 2.5 V operation with 5 V tolerant inputs
Independent baud rate generators allowing flexible clock configurations
DMA mode data transfer with configurable trigger levels

Applications

High-speed modem applications requiring fast data processing
Shared network environments needing reduced CPU bandwidth
Industrial systems operating in extended temperature ranges

Procurement Notes

Verify the specific ordering suffix ',512' against official NXP documentation to confirm packaging or reel specifications. Ensure compatibility with PLCC44 footprint requirements. Confirm RoHS compliance status for the specific batch. Validate that the industrial temperature range meets system environmental constraints. Cross-reference pin assignments with existing schematics.

Selection Notes

Select this component when dual serial communication channels are required within a single package. Consider its compatibility with PC16C552 and ST16C2552 designs for direct upgrades. Evaluate the need for 16-byte FIFOs to minimize processor interrupts. Verify voltage level requirements match the target system's logic levels.

Part Context

This part belongs to the SC16C2552B family of dual UARTs. It serves as an enhanced successor to earlier 16C UARTs by adding FIFO memory. The PLCC44 package provides a compact solution for embedded systems. It maintains pin compatibility with legacy components while offering higher performance capabilities.
