Description and Introduction

CMOS single-chip 8-bit microcontrollers The **SC80C31BACN-40** is a microcontroller manufactured by **Philips (now NXP Semiconductors)**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Philips (NXP Semiconductors)  
- **Core:** 80C51 (8-bit microcontroller)  
- **Clock Speed:** Up to **40 MHz**  
- **Operating Voltage:** **4.5V to 5.5V**  
- **Program Memory (ROM):** **None (Requires external ROM)**  
- **RAM (Internal):** **128 bytes**  
- **I/O Pins:** **32 (4 ports of 8 bits each)**  
- **Timers:** **2 × 16-bit timers/counters**  
- **Interrupts:** **5 interrupt sources (2 external, 2 timer, 1 serial)**  
- **Serial Communication:** **UART (Full-duplex)**  
- **Package:** **PLCC-44 (Plastic Leaded Chip Carrier)**  
- **Operating Temperature:** **Commercial (0°C to +70°C)**  

### **Descriptions & Features:**  
- **High-Speed Variant:** The **SC80C31BACN-40** is a high-performance CMOS version of the 80C31 microcontroller, capable of running at **40 MHz**.  
- **External Memory Support:** Unlike some 80C51 variants, this model has **no internal ROM**, requiring external program memory.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Compatibility:** Fully compatible with the **MCS-51 instruction set**.  
- **On-Chip Oscillator:** Includes an integrated oscillator but requires an external crystal or clock source.  
- **Boolean Processor:** Supports bit-level operations for efficient control applications.  
- **Power-Saving Modes:** Features **Idle** and **Power-Down** modes for reduced power consumption.  

This microcontroller is commonly used in industrial control, embedded systems, and automation applications.
