SC16IS750IBS,151

Controllers Overview

The SC16IS750IBS,151 is a single-channel high-performance UART with an I2C-bus or SPI slave interface manufactured by NXP. It supports data rates up to 5 Mbit/s and operates on 2.5 V or 3.3 V power supplies. The device features 64-byte transmit and receive FIFOs, IrDA SIR support up to 115.2 kbit/s, and eight programmable I/O pins. It functions within an industrial temperature range of -40°C to +95°C and is housed in a 24-terminal HVQFN24 package.

Controllers Feature Summary

• Backward-compatible register set with the standard 16C450 UART for simplified software porting
• Integrated automatic RS-485 driver direction control via RTS signal
• Configurable hardware and software flow control mechanisms
• Built-in IrDA encoder and decoder interface

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated devices
• Cellular data communication equipment

Controllers Selection Notes

Select this component when a single UART channel with low-power consumption is required alongside I2C or SPI connectivity. The inclusion of programmable GPIOs makes it suitable for designs needing additional digital control lines without extra chips. Ensure the host system supports the selected bus protocol and that the 24-TSSOP or HVQFN24 package fits the PCB layout constraints.

Controllers Part Context

This part belongs to the SC16IS740/750/760 family from NXP Semiconductors. While functionally similar to the SC16IS760, the SC16IS750 is distinguished by its lower maximum SPI clock speed of 4 Mbit/s compared to the SC16IS760's 15 Mbit/s. It differs from the SC16IS740 by providing eight additional programmable I/O pins.

Controllers Replacement Considerations

SC16IS760IBS offers identical functionality with higher SPI clock speeds. SC16IS740IPW provides equivalent UART performance but lacks the programmable I/O pins and uses a TSSOP16 package.
