Description and Introduction

SC16C650A; Universal Asynchronous Receiver/Transmitter (UART) with 32-byte FIFO and infrared (IrDA) encoder/decoder The SC16C650AIA44 is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by NXP. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** NXP Semiconductors  
- **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Voltage:** 3.3V or 5V (selectable)  
- **Data Rate:** Up to 5 Mbps  
- **FIFO Depth:** 64 bytes (transmit and receive)  
- **Interface:** Parallel (8-bit)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Clock Frequency:** Up to 24 MHz  

### **Descriptions:**
- The SC16C650AIA44 is a high-performance UART with 64-byte FIFOs for both transmit and receive operations.  
- It supports auto hardware and software flow control (RTS/CTS, XON/XOFF).  
- The device is compatible with industry-standard 16C450 and 16C550 UARTs but offers enhanced features.  
- It includes programmable baud rate generation and supports IrDA (Infrared Data Association) for serial infrared communication.  

### **Features:**
- **64-byte FIFOs** for improved data handling.  
- **Selectable 3.3V or 5V operation** for flexible power supply compatibility.  
- **Auto flow control** (RTS/CTS, XON/XOFF).  
- **Programmable baud rate generator** with a wide range of divisors.  
- **Infrared (IrDA) encoder/decoder** support.  
- **Industrial temperature range** (-40°C to +85°C).  
- **Low power consumption** with sleep mode.  
- **Industrial-standard PLCC package** for reliable mounting.  

This information is strictly based on the manufacturer's specifications.

Application Scenarios & Design Considerations

SC16C650A; Universal Asynchronous Receiver/Transmitter (UART) with 32-byte FIFO and infrared (IrDA) encoder/decoder

Alternative Part Number

  • ST16C650AIQ44 --: Pin-compatible UART with the same 44-pin PLCC footprint and equivalent register set, widely used as a drop-in replacement for the SC16C650 family.
  • XR16C850IM-F --: Similar single-channel UART with 128-byte FIFO and comparable feature set; requires minor configuration differences but is functionally close.
  • TL16C550CIFN --: Industry-standard 16C550-compatible UART with 16-byte FIFO; lower FIFO depth than the original but broadly available and electrically compatible with adaptation.
