SC16C750BIB64,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C750BIB64,151 is a single-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP Semiconductors. It operates at supply voltages of 2.5 V, 3.3 V, or 5 V with an industrial temperature range of -40 °C to +85 °C. The device features 64-byte transmit and receive FIFOs, supporting data rates up to 3 Mbit/s at 5 V, 2 Mbit/s at 3.3 V, and 1 Mbit/s at 2.5 V. It utilizes a parallel interface within an LQFP-64 package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Pin-compatible with industry-standard TL16C750/ST16C450 devices while offering enhanced performance through larger FIFO buffers.
• Includes automatic hardware flow control using RTS and CTS signals to manage data throughput efficiently.
• Supports internal loopback mode for on-board diagnostics and fault isolation without external connections.
• Provides programmable baud rate generation with support for independent transmitter and receiver clock inputs.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Serial data communication interfaces in industrial automation systems
• Embedded controller connections requiring high-speed asynchronous data transfer
• Hardware flow control implementations in shared network environments

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix IB64 confirms the LQFP-64 plastic low profile quad flat package variant. Confirm RoHS compliance status and lead-free material declarations against current manufacturer documentation prior to procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a single UART channel with 64-byte FIFOs is required for parallel bus interfacing. Ensure the system design accommodates the LQFP-64 package dimensions and thermal requirements for the specified industrial temperature range.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C750B family of UARTs, which are backward compatible with the 16C450 register set. The IB64 designation specifically identifies the LQFP-64 package version, distinguishing it from PLCC44 or HVQFN32 variants within the same functional family.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Direct pin-compatible replacements include the TL16C750 and ST16C450. Verify software compatibility with the standard 16C450 register set if migrating from legacy components.
