SC16C652BIB48,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C652BIB48,128 is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP Semiconductors. It operates at supply voltages of 5 V, 3.3 V, and 2.5 V within 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 up to 3 Mbit/s at 2.5 V. It features 32-byte transmit and receive FIFOs, IrDA encoder/decoder support, and independent programmable baud rate generators. Packaged in LQFP48, it is pin-compatible with the SC16C2550.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment against the LQFP48 specification. Ensure environmental compliance documentation matches project requirements. Review datasheet revisions for any functional updates prior to integration.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual UART functionality with high throughput is required. The 32-byte FIFOs are suitable for applications demanding reduced processor intervention. Verify voltage compatibility with the target system's 5 V, 3.3 V, or 2.5 V rails. Consider the LQFP48 package constraints for PCB layout and thermal management.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C652B series represents an enhancement over previous generations like the SC16C2550, offering increased FIFO depth. It serves as a drop-in replacement for legacy UARTs while providing modern features such as IrDA support and higher data rates. The IB48 suffix denotes the specific LQFP48 plastic low profile quad flat package variant.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C652B is functionally equivalent to the 16C2450 and pin-compatible with the SC16C2550. Software compatibility extends to the 16C450 and 16C550 standards. Verify that substitute components maintain the same FIFO depth and voltage operating ranges.
