Description and Introduction

Quad UART with 16-Byte FIFOs The TL16C554FN is a quad universal asynchronous receiver/transmitter (QUART) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage:** 3.3V or 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 1.5 Mbps  
- **Number of Channels:** 4 independent UART channels  
- **FIFO Depth:** 16-byte transmit and receive FIFOs per channel  
- **Package:** 68-pin PLCC (Plastic Leaded Chip Carrier)  

### **Descriptions:**  
The TL16C554FN is a quad UART IC designed for high-performance serial communication applications. It integrates four independent UART channels, each with 16-byte FIFOs to reduce CPU overhead. It supports programmable baud rates, modem control signals, and interrupt handling, making it suitable for multi-channel serial communication systems.  

### **Features:**  
- Four independent UART channels with full-duplex operation  
- 16-byte transmit and receive FIFOs per channel  
- Programmable baud rate generator (up to 1.5 Mbps)  
- Supports 5-, 6-, 7-, or 8-bit data formats  
- Parity, overrun, framing, and break error detection  
- Modem control functions (CTS, RTS, DSR, DTR, RI, DCD)  
- Automatic software/hardware flow control  
- Interrupt prioritization and masking  
- Compatible with 3.3V and 5V systems  

This device is commonly used in industrial automation, networking equipment, and embedded systems requiring multiple serial ports.
