Description and Introduction

Dual asynchronous receiver/transmitter (DUART) The SCC2681AC1A44 is a UART (Universal Asynchronous Receiver/Transmitter) integrated circuit manufactured by PHILIPS. Below are its specifications, descriptions, and features based on the available knowledge base:

### **Specifications:**
- **Manufacturer:** PHILIPS  
- **Type:** UART (Universal Asynchronous Receiver/Transmitter)  
- **Package:** Likely a 40-pin DIP (Dual In-line Package) or similar  
- **Operating Voltage:** Typically 5V (exact voltage range may vary; check datasheet for confirmation)  
- **Data Rate:** Supports standard UART baud rates (exact maximum baud rate depends on clock input)  
- **Interface:** Parallel and serial communication support  
- **Clock Input:** Requires an external crystal or clock source for baud rate generation  

### **Descriptions:**
- The SCC2681AC1A44 is a UART IC designed for serial communication in embedded systems.  
- It facilitates asynchronous data transfer between a microprocessor and peripheral devices.  
- Features dual full-duplex UART channels (exact number depends on variant; some models have two channels).  
- Includes programmable baud rate generators, interrupt handling, and FIFO buffers (if applicable).  

### **Features:**
1. **Dual UART Channels:** Supports two independent serial ports (if applicable to this variant).  
2. **Programmable Baud Rate:** Adjustable via an internal or external clock source.  
3. **FIFO Buffers:** Helps reduce CPU overhead by buffering incoming/outgoing data.  
4. **Interrupt Support:** Configurable interrupts for efficient data handling.  
5. **Modem Control Signals:** Includes RTS, CTS, DTR, DSR, and other modem interface signals.  
6. **Compatibility:** Works with standard microprocessor buses (e.g., Intel/Motorola bus interfaces).  

For precise electrical characteristics, pin configurations, and timing diagrams, refer to the official **PHILIPS SCC2681AC1A44 datasheet**.
