Description and Introduction

4-BIT SINGLE-CHIP MICROCONTROLLER FOR SMALL GENERAL-PURPOSE INFRARED REMOTE CONTROL TRANSMITTER The UPD17228 is a microcontroller manufactured by NEC (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features based on available information:  

### **Manufacturer:** NEC (Renesas Electronics)  
### **Part Number:** UPD17228  

### **Description:**  
The UPD17228 is a 4-bit microcontroller designed for embedded control applications. It integrates a CPU core, memory, and I/O functions, making it suitable for consumer electronics, industrial control, and other low-power applications.  

### **Key Features:**  
- **CPU:** 4-bit microcontroller  
- **Clock Speed:** Varies depending on the model (specific frequency not always documented)  
- **Memory:**  
  - ROM (Mask ROM) for program storage  
  - RAM for data storage (size varies by model)  
- **I/O Ports:** Multiple general-purpose I/O pins  
- **Timers/Counters:** Built-in timer/counter functions  
- **Low Power Consumption:** Suitable for battery-operated devices  
- **Package Type:** Likely available in DIP or SOP packages (exact package depends on variant)  
- **Operating Voltage:** Typically operates at low voltages (e.g., 2.7V to 5.5V, exact range may vary)  

### **Applications:**  
- Consumer electronics  
- Remote controls  
- Small embedded systems  
- Industrial control devices  

### **Note:**  
Since this is an older microcontroller, detailed public datasheets may be limited. For exact specifications, refer to NEC/Renesas documentation or legacy technical support.
