Description and Introduction

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

### **Specifications:**
- **Manufacturer:** EXAR  
- **Part Number:** XR16L2552IJ  
- **Type:** Dual UART  
- **Data Rate:** Up to 3 Mbps  
- **Operating Voltage:** 3.3V  
- **FIFO Depth:** 128 bytes (per channel)  
- **Interface:** Parallel (8-bit)  
- **Package:** PLCC-44  

### **Descriptions:**
- The XR16L2552IJ is a high-performance dual-channel UART designed for high-speed serial communication.  
- It supports independent transmit and receive operations on both channels.  
- It includes 128-byte FIFOs for both transmit and receive operations to reduce CPU overhead.  
- The device is suitable for applications requiring reliable serial communication, such as industrial automation, networking, and embedded systems.  

### **Features:**
- **Dual UART Channels:** Two independent full-duplex UARTs in a single chip.  
- **128-Byte FIFOs:** Reduces CPU interrupts and improves data throughput.  
- **High-Speed Operation:** Supports baud rates up to 3 Mbps.  
- **Programmable Features:** Includes baud rate generators, modem control signals, and interrupt handling.  
- **Low Power Consumption:** Designed for energy-efficient applications.  
- **Industrial Temperature Range:** Operates reliably in harsh environments.  
- **Compatibility:** Works with industry-standard UART protocols.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official EXAR datasheet.
