Description and Introduction

Universal asynchronous receiver/transmitter (UART) The SCC2691AE1N24 is a Universal Asynchronous Receiver/Transmitter (UART) manufactured by PHILIPS. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** PHILIPS  
- **Part Number:** SCC2691AE1N24  
- **Type:** UART (Universal Asynchronous Receiver/Transmitter)  
- **Data Rate:** Up to 1 Mbps  
- **Operating Voltage:** 5V  
- **Package:** 24-pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) (specific variant dependent)  
- **Interface:** Parallel (microprocessor-compatible)  

### **Descriptions:**
- The SCC2691AE1N24 is a single-channel UART designed for asynchronous serial communication.  
- It supports full-duplex operation with independent receiver and transmitter sections.  
- It includes a programmable baud rate generator and features automatic wake-up mode for multiprocessor communication.  

### **Features:**
- **Programmable Baud Rate Generator:** Supports a wide range of data rates.  
- **FIFO Buffers:** 16-byte transmit and receive FIFOs to reduce CPU overhead.  
- **Interrupt Support:** Multiple interrupt sources with prioritization.  
- **Modem Control Signals:** Includes RTS, CTS, DTR, DSR, CD, and RI signals.  
- **Loopback Mode:** For diagnostic testing.  
- **Software-Compatible:** With industry-standard UARTs like the 16C450.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and timing diagrams, refer to the official PHILIPS documentation.
