SC16C652BIB48,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C652BIB48,151 is a dual-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP USA Inc. 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 serial 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, independent programmable baud rate generators, and IrDA encoder/decoder support. The component is housed in a 48-lead LQFP48 plastic package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual UART channels with 32-byte FIFOs for reduced CPU bandwidth requirements
• Support for standard modem interface or infrared IrDA encoder/decoder
• Independent hardware and software flow control mechanisms
• Internal loop-back capability for on-board diagnostics

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial data communication systems requiring high-speed asynchronous transfer

• Applications interfacing with high-speed modems and data compression schemes

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and revision level. Ensure compatibility with existing system voltage levels and clock frequencies before integration. Confirm that the LQFP48 footprint matches the target PCB design constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when dual independent UART channels are required with enhanced FIFO depth compared to legacy 16C450 devices. It serves as a pin-compatible upgrade for designs previously using the SC16C2550 or ST16C2450. Consider the 5 Mbit/s maximum data rate capability for high-throughput applications.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C652B family of dual UARTs. It is functionally equivalent to the 16C2450 upon power-up and offers software compatibility with industry standards like the 16C450 and 16C550. The IB48 suffix specifically denotes the LQFP48 package variant.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C652B is pin compatible with the SC16C2550. It provides an upward solution over the 16C2550 by doubling the FIFO size from 16 bytes to 32 bytes.
