SC16IS850LIPW,118

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16IS850LIPW,118 is a single-channel UART with an I2C-bus/SPI interface. It operates at 1.8 V and supports data rates up to 5 Mbit/s in 16x clock mode. The device features 128-byte transmit and receive FIFOs and is backward-compatible with the 16C450 standard. It includes automatic hardware and software flow control, IrDA SIR support up to 115.2 kbit/s, and automatic RS-485 direction control. Sleep current is less than 5 µA at 1.8 V. It is housed in a TSSOP24 package (SOT355-1) and functions within an industrial temperature range of -40 °C to +85 °C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Backward-compatible register set with the widely used 16C450 standard for easy software porting.
• Integrated 128-byte transmit and receive FIFOs to reduce external CPU bandwidth requirements.
• Automatic RS-485 driver direction control via RTS signal or inversion.
• Built-in IrDA encoder and decoder interface supporting speeds up to 115.2 kbit/s.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Factory automation and process control
• Portable and battery operated devices
• Cellular data devices

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the ordering suffix '118' against official NXP documentation to confirm specific reel packaging details. Ensure the TSSOP24 package variant matches the required board layout. Confirm that the 1.8 V operating voltage aligns with the target system power rails. Check for any RoHS compliance markers on the component marking.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a low-voltage, single-channel UART bridge is required with high throughput capabilities. The 128-byte FIFOs are suitable for applications demanding reduced processor intervention. Verify compatibility with existing 16C450-based software drivers. Consider the TSSOP24 package constraints for PCB space limitations.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16IS850L family of single UARTs with I2C/SPI interfaces. It shares functional similarities with the SC16IS750 but offers double the FIFO depth. It is designed as a drop-in replacement for legacy UARTs in modern low-power embedded systems requiring serial-to-serial conversion.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

SC16IS750IBS: Offers similar functionality but with smaller 64-byte FIFOs. SC16IS741: Provides single-channel UART with 64-byte FIFOs in a TSSOP16 package. Verify pinout compatibility and FIFO size requirements before substitution.
