CMOS 4-BIT MICROCONTROLLER The **TMP47C200AN** is a microcontroller manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features based on available information:
### **Specifications:**
- **Manufacturer:** TOSHIBA
- **Series:** TMP47C200AN
- **Core Architecture:** 4-bit microcontroller
- **Program Memory:** ROM-based (exact size not specified in standard documentation)
- **RAM:** Limited internal RAM (exact size not specified)
- **Operating Voltage:** Typically **5V** (standard for microcontrollers of this era)
- **Clock Speed:** Not explicitly stated, but likely operates in the **kHz to low MHz range** (common for 4-bit microcontrollers).
- **I/O Ports:** Multiple general-purpose I/O pins (exact count varies by application).
- **Package Type:** Likely **DIP (Dual In-line Package)** or similar through-hole package.
### **Descriptions & Features:**
- Designed for **embedded control applications**, such as consumer electronics, appliances, and simple automation.
- **4-bit processing** optimized for cost-sensitive, low-complexity tasks.
- **On-chip ROM** for firmware storage (mask-programmed, not user-reprogrammable).
