Description and Introduction

5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.), with 64-byte FIFOs and infrared (IrDA) encoder/decoder The SC16C654BIA68 is a UART (Universal Asynchronous Receiver/Transmitter) manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** PHILIPS (NXP Semiconductors)  
- **Model:** SC16C654BIA68  
- **Type:** Quad UART (4-channel)  
- **Interface:** Parallel  
- **Data Rate:** Up to 5 Mbps  
- **Voltage Supply:** 3.3V or 5V operation  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** PLCC-68  

### **Descriptions:**  
- The SC16C654BIA68 is a high-performance quad UART designed for serial communication applications.  
- It supports four independent UART channels, each with a 64-byte FIFO (First-In-First-Out) buffer to reduce CPU overhead.  
- Compatible with industry-standard 16C450/16C550 UARTs but with enhanced features.  

### **Features:**  
- **Four Independent UART Channels:** Each with full-duplex operation.  
- **64-Byte FIFOs:** Per channel for both transmit and receive.  
- **Programmable Baud Rate:** Supports up to 5 Mbps.  
- **Automatic Flow Control:** Hardware (RTS/CTS) and software (XON/XOFF) support.  
- **Infrared (IrDA) Encoder/Decoder:** Optional support for infrared communication.  
- **Low Power Consumption:** Suitable for power-sensitive applications.  
- **Industrial Temperature Range:** Operates reliably in harsh environments.  
- **Legacy Compatibility:** Backward-compatible with 16C450/16C550 UARTs.  

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

Application Scenarios & Design Considerations

5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.), with 64-byte FIFOs and infrared (IrDA) encoder/decoder

Alternative Part Number

  • ST16C654CQ64 --: Pin-compatible quad UART with 64-byte FIFOs from the MaxLinear/Exar ST16C series, a well-known drop-in replacement family for the SC16C654.
  • XR16C854CQ64 --: Quad UART with 128-byte FIFOs offering similar functionality and register compatibility, suitable when higher FIFO depth is acceptable.
  • TL16C754BPN --: TI quad UART with 64-byte FIFOs providing comparable serial channel functionality for designs needing an alternative vendor source.
  • XR16L784IV-F --: Quad UART with 64-byte FIFOs in a similar 68-pin package, functionally comparable to the SC16C654B and widely used as a drop-in alternative.
  • ST16C654CJ68 --: Direct quad UART with 64-byte FIFOs in 68-pin PLCC, electrically and functionally equivalent to the SC16C654BIA68.
