Description and Introduction

Dual UART with Parallel Port And Without FIFO The TL16C452FNR is a dual universal asynchronous receiver/transmitter (DUART) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Dual UART (DUART)  
- **Data Rate:** Up to 1 Mbps  
- **FIFO Depth:** 16-byte transmit and receive FIFOs per channel  
- **Operating Voltage:** 5V  
- **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to 70°C)  
- **Interface:** Parallel (8-bit)  
- **Features Modem Control Signals:** CTS, RTS, DSR, DTR, RI, DCD  

### **Descriptions and Features:**  
- Provides two independent UART channels in a single package.  
- Supports programmable baud rates with a built-in baud rate generator.  
- Includes 16-byte FIFOs to reduce CPU overhead.  
- Compatible with industry-standard UARTs (e.g., 16C450, 16C550).  
- Features interrupt-driven operation with prioritized interrupts.  
- Supports full-duplex operation for asynchronous serial communication.  
- Includes loopback mode for diagnostic testing.  
- Suitable for applications such as industrial control, networking, and embedded systems.  

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