Description and Introduction

LAP-B CONTROLLER(Link Access Procedure Balanced mode) The **UPD72107CW** is a microcontroller manufactured by **NEC**. Below are the factual specifications, descriptions, and features based on available technical documentation:  

### **Manufacturer:** NEC (Now part of Renesas Electronics)  

### **Description:**  
The **UPD72107CW** is a **4-bit single-chip microcontroller** designed for embedded control applications. It integrates a CPU core, memory, and I/O peripherals into a single package, making it suitable for cost-sensitive and space-constrained designs.  

### **Key Features:**  
- **CPU Architecture:** 4-bit  
- **Operating Voltage:** Typically **5V** (exact range may vary)  
- **Clock Speed:** Up to **several MHz** (specific frequency depends on model variant)  
- **On-Chip Memory:**  
  - **ROM (Program Memory):** Varies by model (e.g., 1KB to 4KB)  
  - **RAM (Data Memory):** Small internal RAM (e.g., 64 bytes to 128 bytes)  
- **I/O Ports:** Multiple general-purpose I/O pins  
- **Timers/Counters:** Built-in timer/counter for timing operations  
- **Interrupts:** Support for hardware and software interrupts  
- **Package Type:** **CW** suffix likely indicates a **Ceramic Windowed (DIP)** package for UV-erasable EPROM versions  

### **Applications:**  
- Consumer electronics  
- Simple control systems  
- Industrial automation  
- Home appliances  

### **Notes:**  
- This microcontroller is an older part, and availability may be limited.  
- Exact specifications may vary by variant (e.g., ROM size, pin count).  

For precise details, refer to the **official NEC (Renesas) datasheet** for the **UPD72107CW**.
