Description and Introduction

ASYNCHRONOUS COMMUNICATIONS ELEMENT WITH AUTOFLOW CONTROL The TL16C550DPFB is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TL16C550DPFB  

### **Description:**  
The TL16C550DPFB is an enhanced UART with 16-byte FIFOs (First-In, First-Out buffers) for both transmit and receive operations. It is designed to reduce CPU overhead in high-speed serial communication applications.  

### **Key Features:**  
- **16-byte FIFOs** for transmit and receive to minimize CPU interrupts  
- **Programmable baud rate generator** (up to 1 Mbps at 16 MHz)  
- **Standard asynchronous communication bits** (start, stop, parity)  
- **Modem control functions** (CTS, RTS, DSR, DTR, RI, DCD)  
- **Autoflow control** (Xon/Xoff, RTS/CTS)  
- **Industrial temperature range** (-40°C to +85°C)  
- **5V operation**  
- **44-pin PLCC package**  
- **Compatible with industry-standard 16C450 and 16C550 UARTs**  
- **Software-compatible with the TL16C450**  

### **Applications:**  
- Embedded systems  
- Industrial automation  
- Networking equipment  
- Point-of-sale terminals  
- Serial communication interfaces  

This information is based solely on the manufacturer's specifications.
