Description and Introduction

5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.), with 64-byte FIFOs and infrared (IrDA) encoder/decoder The **SC16C654BIEC** is a quad UART (Universal Asynchronous Receiver/Transmitter) manufactured by **PHILIPS** (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Number of Channels:** 4 (Quad UART)
- **Data Rate:** Up to 5 Mbps
- **FIFO Depth:** 64 bytes (per channel)
- **Operating Voltage:** 3.3V or 5V
- **Interface:** Parallel (8-bit data bus)
- **Package:** PLCC (Plastic Leaded Chip Carrier)
- **Operating Temperature:** -40°C to +85°C (Industrial grade)
- **Clock Input:** Up to 80 MHz (programmable baud rate generator)

### **Descriptions:**
- The SC16C654BIEC is a high-performance quad UART designed for applications requiring multiple serial communication channels.
- It supports full-duplex operation with independent transmit and receive paths for each UART channel.
- Features include auto flow control (RTS/CTS), software/hardware flow control, and programmable baud rates.
- Suitable for industrial, networking, and embedded systems.

### **Features:**
1. **64-byte FIFOs** (per channel) for reduced CPU overhead.
2. **Auto RTS/CTS Flow Control** for efficient data transfer.
3. **Programmable Baud Rate** with fractional divider.
4. **Infrared (IrDA) Encoder/Decoder** support (1.0 compliant).
5. **Sleep Mode** for power-saving operation.
6. **Industrial Temperature Range** (-40°C to +85°C).
7. **Modem Control Signals** (DTR, DSR, RI, CD).
8. **Compatible with 16550A UART** register set.

This UART is commonly used in multi-port serial communication systems, industrial automation, and networking equipment.
