- **Manufacturer:** EXAR  
- **Model:** XR68C92CJ  
- **Type:** Dual UART (DUART)  
- **Operating Voltage:** 5V  
- **Data Rate:** Up to 1.5 Mbps  
- **Number of Channels:** 2 independent UART channels  
- **FIFO Buffers:** 16-byte TX and RX FIFOs per channel  
- **Interface:** Parallel (8-bit)  
- **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Descriptions:**  
The XR68C92CJ is a CMOS-based dual UART designed for high-performance serial communication applications. It provides two independent full-duplex UART channels with enhanced features such as FIFO buffers, programmable baud rates, and interrupt handling.  

### **Features:**  
- **Dual Full-Duplex UART Channels:** Independent operation for two serial ports.  
- **16-byte FIFOs:** Reduces CPU overhead by buffering transmit and receive data.  
- **Programmable Baud Rates:** Supports up to 1.5 Mbps with an external clock.  
- **Modem Control Signals:** Includes RTS, CTS, DTR, DSR, CD, and RI for each channel.  
- **Interrupt Support:** Flexible interrupt prioritization and masking.  
- **Loopback Mode:** Facilitates diagnostics and testing.  
- **Software-Selectable Configuration:** Data format (5-8 bits), parity (odd/even/none), and stop bits (1, 1.5, 2).  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.
