Description and Introduction

DUAL J-FET INPUT LOW-POWER OPERATIONAL AMPLIFIER The **UPC4064** is a **4-bit single-chip microcomputer** manufactured by **NEC (now Renesas Electronics)**. Below are its specifications, descriptions, and features based on available knowledge:  

### **Specifications:**  
- **Architecture:** 4-bit CMOS microcomputer  
- **ROM:** 1K x 8-bit (Mask ROM)  
- **RAM:** 64 x 4-bit  
- **Clock Speed:** Typically operates at **400 kHz**  
- **I/O Ports:** 4-bit parallel I/O ports  
- **Timers:** Built-in timer/counter  
- **Instruction Set:** Optimized for control applications  
- **Power Supply:** **5V DC** (standard CMOS voltage)  
- **Package:** **16-pin DIP (Dual In-line Package)**  

### **Descriptions:**  
- Designed for **low-power, embedded control applications**  
- Used in **consumer electronics, appliances, and simple control systems**  
- Features **on-chip oscillator** for clock generation  
- Includes **basic arithmetic and logic operations**  

### **Features:**  
- **Low power consumption** (CMOS technology)  
- **Compact and cost-effective** for simple control tasks  
- **Integrated timer** for event counting/delay generation  
- **Mask ROM** for fixed program storage  
- **4-bit data processing** suitable for basic control functions  

This microcomputer was part of NEC’s early **4-bit microcontroller lineup**, primarily used in industrial and consumer electronics. For detailed datasheets or application notes, refer to **NEC (Renesas) documentation**.
