Description and Introduction

INFRARED REMOTE CONTROL SIGNAL TRANSMISSION LSI The TC9243P is a semiconductor device manufactured by Toshiba. Below are the factual details about the part based on available specifications, descriptions, and features:

### **Manufacturer:**  
- **Toshiba** (now part of Kioxia Holdings Corporation following corporate restructuring).  

### **Specifications:**  
1. **Function:**  
   - The TC9243P is a **PLL (Phase-Locked Loop) frequency synthesizer IC**, commonly used in radio frequency (RF) and communication applications.  

2. **Operating Voltage:**  
   - Typically operates at **5V DC** (exact range may vary; refer to datasheet for precise values).  

3. **Frequency Range:**  
   - Designed for **VHF/UHF frequency synthesis**, supporting tuning in radio applications.  

4. **Package Type:**  
   - Likely comes in a **DIP (Dual In-line Package)** or similar through-hole package (exact pin count depends on variant).  

5. **Key Features:**  
   - **Programmable divider** for flexible frequency control.  
   - **Low phase noise** for stable signal generation.  
   - **Serial data interface** (SPI or similar) for microcontroller communication.  

6. **Applications:**  
   - Used in **FM/AM radios, two-way radios, and wireless communication devices**.  

### **Descriptions & Features:**  
- The TC9243P integrates a **phase comparator, voltage-controlled oscillator (VCO) interface, and programmable counters** to generate stable output frequencies.  
- Designed for **low power consumption** in portable devices.  
- May include **lock detection** to indicate PLL synchronization status.  

For exact electrical characteristics, pinout, and timing diagrams, consult the **official Toshiba TC9243P datasheet** (if available in public archives).  

*(Note: Some older Toshiba parts may have limited documentation due to discontinuation.)*
