Description and Introduction

Dual UART with 16-Byte FIFOs & Parallel Port The TL16C552APN is a dual universal asynchronous receiver/transmitter (DUART) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Dual UART (DUART)  
- **Operating Voltage:** 5V  
- **Data Rate:** Up to 1.5 Mbps  
- **Number of Channels:** 2 (independent UART channels)  
- **FIFO Depth:** 16 bytes per channel (Tx and Rx)  
- **Interrupt Support:** Programmable interrupt system  
- **Package:** 68-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  

### **Descriptions and Features:**  
- Provides two independent full-duplex UART channels.  
- Each channel has a 16-byte FIFO for transmit and receive to reduce CPU overhead.

- Includes loopback mode for diagnostic testing.  
- Suitable for serial communication in embedded systems, industrial controls, and networking applications.  

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

Application Scenarios & Design Considerations

Dual UART with 16-Byte FIFOs & Parallel Port

Alternative Part Number

  • ST16C552CJ44 --: Dual UART with parallel port, functionally equivalent to the TL16C552A, available in PLCC package; widely used as a drop-in replacement.
  • SC16C552BIB48 --: Dual UART plus parallel interface with similar register set and feature set, suitable for legacy serial/parallel port designs.
  • XR16C552CJ --: Pin-compatible dual UART with parallel port from the same Exar family, offering comparable functionality for TL16C552A applications.
