nullQuad universal asynchronous receiver/transmitter QUART The **SC68C94A1A** is a dual universal asynchronous receiver/transmitter (DUART) manufactured by **PHILIPS**. Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Manufacturer:** PHILIPS (now NXP Semiconductors)
- **Type:** Dual UART (DUART)
- **Data Rate:** Up to **1 Mbps**
- **Number of Channels:** **2 independent UART channels**
- **Data Bits:** **5, 6, 7, or 8 bits**
- **Stop Bits:** **1, 1.5, or 2 bits**
- **Parity:** **Odd, Even, or No Parity**
- **FIFO Buffers:** **16-byte transmit and receive FIFOs per channel**

- **Package:** **PLCC-44 (Plastic Leaded Chip Carrier)**
- **Operating Temperature Range:** **Commercial (0°C to +70°C)**
### **Descriptions:**
- The **SC68C94A1A** is a CMOS-based **dual UART** designed for asynchronous serial communication.
- It provides **two independent full-duplex UART channels**, each with **16-byte FIFOs** to reduce CPU overhead.
- Supports **programmable baud rates**, interrupt handling, and modem control signals (RTS, CTS, DSR, DCD, RI).
- Ideal for **embedded systems, industrial control, and communication interfaces**.
### **Features:**
- **Dual independent UART channels** with full modem control.
- **16-byte FIFOs** for both transmit and receive on each channel.
- **Automatic software/hardware flow control** (XON/XOFF, RTS/CTS).
- **Programmable baud rate generator** with 1x, 16x, or 64x clock modes.
- **Multi-function interrupt system** with prioritized interrupts.
- **Low-power CMOS technology** for reduced power consumption.
- **Compatible with industry-standard UARTs** (e.g., 16C450, 16C550).
