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 key specifications, descriptions, and features:  

### **Manufacturer:** NXP Semiconductors  

### **Description:**  
The SC16C850IET is a high-performance UART with 64-byte FIFOs (First-In, First-Out buffers) for both transmit and receive operations. It supports data rates up to 5 Mbps and is designed for applications requiring reliable serial communication.  

### **Key Features:**  
- **64-byte TX and RX FIFOs** – Reduces CPU overhead by minimizing interrupts.  
- **High Data Rate** – Supports up to **5 Mbps** at 3.3V and **3 Mbps** at 2.5V.  
- **Operating Voltage:** **2.5V to 5V** (wide voltage range).  
- **Programmable Baud Rate Generator** – Allows flexible baud rate selection.  
- **Auto Hardware/Software Flow Control** – Supports RTS/CTS and XON/XOFF protocols.  
- **Infrared (IrDA) Encoder/Decoder** – Supports IrDA 1.0 (up to 115.2 kbps).  
- **Sleep Mode** – Low-power mode for energy efficiency.  
- **Industrial Temperature Range:** **-40°C to +85°C**.  
- **Package:** **TSSOP-48**.  

### **Applications:**  
- Industrial automation  
- Networking equipment  
- Point-of-sale (POS) terminals  
- Embedded systems  

The SC16C850IET is a drop-in replacement for older UARTs like the 16C550, offering enhanced performance with larger FIFOs and higher speeds.
