Description and Introduction

2.5 V to 3.3 V UART, 5 Mbit/s (max.) with 128-byte FIFOs, infrared (IrDA), and 16 mode or 68 mode parallel bus interface The SC16C850IET is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by NXP Semiconductors. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** NXP Semiconductors  
- **Series:** SC16C850  
- **Package:** TSSOP-48  
- **Operating Voltage:** 3.3V or 5V  
- **Data Rate:** Up to 5 Mbps  
- **FIFO Depth:** 64-byte transmit and receive FIFOs  
- **Interface:** UART (Universal Asynchronous Receiver/Transmitter)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 1  
- **Additional Features:** Auto RTS/CTS flow control, programmable baud rate, infrared (IrDA) encoder/decoder  

### **Descriptions:**  
The SC16C850IET is a single-channel UART designed for high-speed serial communication. It supports both 3.3V and 5V operation and includes 64-byte FIFOs to reduce CPU overhead. It is commonly used in industrial, networking, and embedded applications requiring reliable asynchronous data transfer.  

### **Features:**  
- **64-byte FIFOs** for both transmit and receive to minimize CPU interrupts  
- **Programmable baud rate** with a maximum of 5 Mbps  
- **Auto RTS/CTS hardware flow control**  
- **Infrared (IrDA) support** (1.0 compliant)  
- **Software-selectable baud rate generator**  
- **Industrial temperature range (-40°C to +85°C)**  
- **Low power consumption**  
- **Compatible with industry-standard 16C450 and 16C550 UARTs**  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

2.5 V to 3.3 V UART, 5 Mbit/s (max.) with 128-byte FIFOs, infrared (IrDA), and 16 mode or 68 mode parallel bus interface

Alternative Part Number

  • XR16L580IL --: Single-channel UART with 128-byte FIFO in a similar 32-pin package, functionally comparable to the SC16C850.
  • ST16C550CJ --: Widely available single UART with 16-byte FIFO, a common drop-in style replacement for 16C550-class devices.
  • TL16C550CPT --: Industry-standard 16C550-compatible UART with 16-byte FIFO, easy to source and well documented.
  • XR16V850IL --: Pin-compatible UART with similar 128-byte FIFO and high-speed interface, widely used as a drop-in replacement for the SC16C850 family.
  • TL16C850CIB --: Single-channel UART with comparable FIFO depth and parallel bus interface, functionally equivalent for most serial expansion designs.
  • ST16C850IJ --: Legacy-compatible UART offering similar register set and FIFO features, suitable when the original NXP part is unavailable.
