Description and Introduction

2.25V TO 5.5V DUART WITH 16-BYTE FIFO The XR16L2552IJ is a UART (Universal Asynchronous Receiver/Transmitter) integrated circuit manufactured by Exar Corporation (now part of MaxLinear). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage:** 3.3V or 5V operation  
- **Data Rate:** Up to 3 Mbps  
- **Number of Channels:** Dual UART (2 independent channels)  
- **FIFO Depth:** 128-byte transmit and receive FIFOs per channel  
- **Interface:** Parallel (8-bit)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 52-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**  
- The XR16L2552IJ is a dual UART with enhanced features for high-speed serial communication.  
- It supports programmable baud rates and includes large FIFOs to reduce CPU overhead.  
- Designed for industrial, networking, and embedded applications requiring reliable serial communication.  

### **Features:**  
- **128-byte FIFOs** for both transmit and receive per channel  
- **Auto hardware/software flow control** (RTS/CTS, XON/XOFF)  
- **Programmable baud rate generator** with fractional divider  
- **Infrared (IrDA) encoder/decoder** support (1.0 and 1.1 compliant)  
- **Multi-drop mode** (9-bit address detection)  
- **Sleep mode** for power savings  
- **Industrial temperature range** (-40°C to +85°C)  
- **Compatible with industry-standard 16C550 UARTs**
