Description and Introduction

SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE The XR16L580 is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by EXAR Corporation. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Interface:** UART (Universal Asynchronous Receiver/Transmitter)  
- **Data Rate:** Up to 3 Mbps  
- **FIFO Depth:** 64 bytes (transmit and receive)  
- **Voltage Supply:** 3.3V or 5V operation  
- **Package Options:** 48-pin LQFP, 32-pin LQFP  
- **Operating Temperature Range:** -40°C to +85°C  
- **Additional Features:**  
  - Auto hardware/software flow control  
  - Programmable baud rate generator  
  - Infrared (IrDA) encoder/decoder support  
  - Sleep mode for power savings  

### **Descriptions:**
- The XR16L580 is a high-performance UART designed for embedded applications requiring reliable serial communication.  
- It supports full-duplex asynchronous data transfer with configurable data formats (5-9 bits, parity, stop bits).  
- The device includes advanced features such as FIFO buffering, flow control, and low-power modes.  

### **Features:**
- **64-byte TX/RX FIFOs** – Reduces CPU overhead by minimizing interrupts.  
- **Auto RTS/CTS Flow Control** – Hardware-based handshaking for reliable data transfer.  
- **Programmable Baud Rate** – Flexible clock divider for various communication speeds.  
- **Infrared Support (IrDA 1.0)** – Optional IrDA encoding/decoding for wireless communication.  
- **Sleep Mode** – Low-power state to conserve energy when inactive.  
- **Industrial Temperature Range** – Suitable for harsh environments (-40°C to +85°C).  

This information is based on EXAR's official documentation for the XR16L580 UART.
