Description and Introduction

Universal Asynchronous Receiver/Transmitter (UART) with 16-byte FIFO and infrared (IrDA) encoder/decoder The SC16C550IN40 is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by Philips Semiconductors (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **PH (Philips Semiconductors, now NXP Semiconductors)**

### **Specifications:**  
- **Interface Type:** UART (Universal Asynchronous Receiver/Transmitter)  
- **Data Rate:** Up to 1.5 Mbps  
- **Operating Voltage:** 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-pin PDIP (Plastic Dual In-line Package)  
- **FIFO Buffers:** 16-byte transmit and receive FIFOs  
- **Clock Frequency:** Up to 40 MHz  
- **Interrupt Support:** Programmable interrupt generation  
- **Flow Control:** Hardware (RTS/CTS) and software (XON/XOFF) flow control  

### **Descriptions:**  
- The SC16C550IN40 is a single-channel UART designed for serial communication applications.  
- It is compatible with the industry-standard 16C450 and 16C550 UARTs but includes enhanced features such as FIFO buffers.  
- It supports full-duplex asynchronous communication and is commonly used in embedded systems, industrial automation, and telecommunications.  

### **Features:**  
- **16-byte FIFOs** for both transmit and receive operations to reduce CPU overhead.  
- **Auto-flow control** with RTS/CTS signals.  
- **Programmable baud rate generator** for flexible communication speeds.  
- **Modem control signals** (DTR, DSR, RI, CD).  
- **Software-selectable baud rates** (up to 1.5 Mbps at 40 MHz).  
- **Industrial temperature range** (-40°C to +85°C) for harsh environments.  
- **Low power consumption** in standby mode.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Universal Asynchronous Receiver/Transmitter (UART) with 16-byte FIFO and infrared (IrDA) encoder/decoder

Alternative Part Number

  • ST16C550CJ44 --: Pin-compatible UART with 16-byte FIFO from the ST16C550 series, widely used as a direct replacement for the SC16C550 in 44-pin PLCC packages.
  • TL16C550CFN --: Industry-standard 16C550-compatible UART with 16-byte FIFO, well documented and readily available, suitable for drop-in functional replacement.
  • XR16C550CJ --: Another 16C550-compatible UART with 16-byte FIFO in PLCC package, offering equivalent functionality and good availability as a second-source option.
  • XR16C550CJ44 --: Industry-standard 16C550-compatible UART with equivalent register set and FIFO depth, available in PLCC-44 and commonly substituted for Philips SC16C550 devices.
  • TL16C550CIFN --: TI's 16C550-compatible asynchronous UART with 16-byte FIFO and similar feature set, suitable functional replacement when package and supply voltage are matched.
