SC16IS750IBS,157

Controllers Overview

The SC16IS750IBS,157 is a single-channel high-performance UART featuring an I2C-bus or SPI slave interface. It supports data rates up to 5 Mbit/s and operates on 2.5 V or 3.3 V power supplies within an industrial temperature range of -40 °C to +95 °C. The device includes 64-byte transmit and receive FIFOs, eight programmable I/O pins, and built-in IrDA SIR support for speeds up to 115.2 kbit/s. It utilizes an HVQFN24 package (4 x 4 x 0.85 mm) and maintains backward compatibility with the 16C450 register set.

Controllers Feature Summary

• Backward-compatible internal register set with the widely used 16C450 standard
• Integrated automatic RS-485 driver direction control via RTS signal
• Built-in IrDA encoder and decoder supporting SIR protocol
• Supports auto hardware flow control using RTS/CTS signals

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated devices requiring low current consumption
• Cellular data devices

Controllers Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the selected variant matches the required interface configuration and thermal performance needs for the target application environment.

Controllers Selection Notes

Select this component when a single UART channel with I2C or SPI connectivity is required alongside GPIO expansion. The inclusion of eight programmable I/O pins distinguishes it from the SC16IS740. Consider the SC16IS760 if higher SPI clock speeds or faster IrDA transmission are necessary, as the SC16IS750 is limited to 4 Mbit/s SPI and 115.2 kbit/s IrDA.

Controllers Part Context

This part belongs to the SC16IS740/750/760 family of bridge ICs designed for seamless protocol conversion between I2C/SPI and RS-232/RS-485. The SC16IS750 specifically adds eight programmable I/O pins compared to the base SC16IS740 model, while sharing identical UART performance characteristics and FIFO depths.

Controllers Replacement Considerations

SC16IS760IBS serves as a functional replacement offering enhanced SPI and IrDA capabilities. SC16IS750IPW provides the same functionality in a TSSOP24 package instead of HVQFN24.
