Description and Introduction

Quad UART with 16-Byte FIFOs The TL16C554IFN is a quad universal asynchronous receiver/transmitter (QUART) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage:** 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 1.5 Mbps  
- **Number of Channels:** 4 (Quad UART)  
- **FIFO Depth:** 16 bytes per channel (Tx and Rx)  
- **Package Type:** PLCC-68  
- **Interface:** Parallel  

### **Descriptions:**  
- The TL16C554IFN is a quad UART IC designed for asynchronous serial data communication.  
- It integrates four independent UART channels, each with 16-byte FIFOs to reduce CPU overhead.  
- Supports programmable baud rates, parity, and data formats.  
- Compatible with industry-standard 16C450 and 16C550 UARTs.  

### **Features:**  
- **Independent UART Channels:** Four full-duplex UARTs in a single chip.  
- **16-Byte FIFOs:** Reduces interrupt loading on the host processor.  
- **Programmable Baud Rate:** Supports up to 1.5 Mbps.  
- **Modem Control Signals:** Includes CTS, RTS, DSR, DTR, RI, and DCD for each channel.  
- **Auto Flow Control:** Hardware or software-selectable.  
- **Sleep Mode:** Low-power mode to reduce power consumption.  
- **Industrial Temperature Range:** Suitable for harsh environments.  

This information is based on TI's official documentation for the TL16C554IFN.
