SC16C752IB48,157

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C752IB48,157 is a dual universal asynchronous receiver/transmitter (UART) manufactured by NXP USA Inc. It features two independent UART channels with 64-byte transmit and receive FIFOs. The device supports data rates up to 5 Mbits/s at 3.3 V and 5 V, and up to 3 Mbits/s at 2.5 V. It operates within a voltage range of 2.5 V, 3.3 V, and 5 V. The component is housed in a 48-lead LQFP plastic package (SOT313-2). Key specifications include programmable baud rate generation, hardware/software flow control, and support for 5, 6, 7, or 8-bit characters with configurable parity and stop bits.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Pin-compatible with SC16C2550 while offering enhanced features via an Enhanced Feature Register.
• Supports both hardware flow control (Auto-RTS/Auto-CTS) and software flow control (Xon/Xoff).
• Includes internal loop-back capability for on-board diagnostics and error detection.
• Features a fully prioritized interrupt system with six distinct interrupt levels.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring high-speed serial data transfer.
• Embedded systems needing multiple UART interfaces with DMA capabilities.
• Modem interface applications utilizing full modem control signal handling.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix ',157' against official NXP documentation to confirm packaging details and availability status. Ensure compatibility with the 48-LQFP footprint during PCB layout. Confirm RoHS compliance and material declarations for the specific batch code prior to integration into production environments.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a pin-compatible replacement for the SC16C2550 is required with added FIFO and flow control enhancements. Consider the 48-pin LQFP package constraints for board space. Evaluate power consumption requirements as the device supports a programmable sleep mode to reduce current draw during idle periods.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C752 belongs to the SC16C75x family of dual UARTs designed for high-performance serial communication. It serves as an evolution of earlier Philips Semiconductors designs, integrating advanced buffer management and flow control logic. The IB48 variant specifically denotes the LQFP48 package configuration used in surface-mount applications.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C752 is explicitly documented as pin-compatible with the SC16C2550. Designers replacing legacy components should verify that the enhanced feature register configurations do not conflict with existing firmware assumptions regarding standard 16C550 behavior.
