Description and Introduction

LOW POWER MULTIPLE RS-232 DRIVERS AND RECEIVERS The ST75C185C is a CMOS integrated circuit manufactured by STMicroelectronics. It is a dual universal asynchronous receiver/transmitter (UART) designed for serial data communication.  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Data Rate:** Up to 1.5 Mbps  
- **Number of Channels:** 2 (Dual UART)  
- **FIFO Buffers:** 16-byte transmit and receive FIFOs per channel  
- **Interface:** Parallel (8-bit)  
- **Package Options:** PLCC, LQFP  

### **Descriptions and Features:**  
- **Dual Full-Duplex UART:** Supports two independent serial channels.  
- **16-Byte FIFOs:** Reduces CPU overhead by buffering data.  
- **Programmable Baud Rate:** Supports flexible data rates up to 1.5 Mbps.  
- **Modem Control Signals:** Includes RTS, CTS, DSR, DTR, RI, and DCD for modem interfacing.  
- **Automatic Flow Control:** Hardware (RTS/CTS) and software (XON/XOFF) flow control options.  
- **Interrupt Support:** Multiple interrupt sources with prioritization.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Compatibility:** Industry-standard UART functionality, compatible with 16C450/16C550.  

The ST75C185C is commonly used in industrial control, networking, and embedded systems requiring reliable serial communication.
