Description and Introduction

5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with 16-byte FIFOs The SC16C2550BIA44 is a dual universal asynchronous receiver and transmitter (DUART) manufactured by Philips (now NXP Semiconductors). Here are its key specifications, descriptions, and features:

### **Specifications:**
1. **Manufacturer:** Philips (NXP Semiconductors)  
2. **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  
3. **Operating Voltage:** 3.3V or 5V  
4. **Data Rate:** Up to 5 Mbps  
5. **Number of Channels:** 2 independent UART channels  
6. **FIFO Buffers:** 64-byte transmit and receive FIFOs per channel  
7. **Interface:** Parallel (8-bit)  
8. **Operating Temperature Range:** -40°C to +85°C  
9. **Clock Input:** Up to 80 MHz  

### **Descriptions:**
- The SC16C2550BIA44 is a high-performance dual UART designed for industrial, embedded, and communication applications.  
- It supports programmable baud rates, automatic hardware/software flow control, and modem control signals.  
- It is compatible with industry-standard UARTs (e.g., 16C450, 16C550).  
- The device is ideal for systems requiring reliable serial communication with minimal CPU overhead.  

### **Features:**
1. **Dual Independent UART Channels:** Each with full modem control.  
2. **Large FIFOs:** 64-byte transmit and receive FIFOs reduce CPU interrupts.  
3. **Programmable Baud Rate:** Supports standard and non-standard rates.  
4. **Auto Flow Control:** Hardware (RTS/CTS) and software (XON/XOFF) flow control.  
5. **Low Power Consumption:** Suitable for power-sensitive applications.  
6. **Industrial Temperature Range:** Operates reliably in harsh environments.  
7. **Interrupt Support:** Includes prioritized interrupt handling.  
8. **Compatibility:** Works with 3.3V and 5V systems.  

This device is commonly used in networking equipment, industrial automation, and embedded systems requiring robust serial communication.

Application Scenarios & Design Considerations

5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with 16-byte FIFOs

Alternative Part Number

  • ST16C2550CQ48 --: Pin-compatible dual UART with 16-byte FIFOs from the original Exar/MaxLinear ST16C2550 family, widely used as a drop-in replacement for the SC16C2550 in 44/48-pin packages.
  • XR16C2550IM48 --: Dual-channel UART with compatible register set and FIFO depth, offered in similar package options and commonly cross-referenced for SC16C2550 designs.
  • TL16C2550IPFB --: TI dual UART with 16-byte FIFOs and a compatible programming interface, frequently used as an alternative when the NXP/Philips SC16C2550 is unavailable.
  • TL16C2550PFB --: Dual-channel UART with 16-byte FIFOs and compatible register interface, available in TQFP packages, suitable functional replacement with similar feature set.
  • XR16C2550IM --: Dual UART with 16-byte FIFOs and industry-standard 16C550 register compatibility, offering similar functionality and package options for the SC16C2550BIA44.
