Description and Introduction

Low-Voltage ETR Controller with On-Chip LCD Driver The LC72348W is a CMOS LSI chip manufactured by SANYO (now part of ON Semiconductor). Below are its key specifications, descriptions, and features:

### **Specifications:**
1. **Manufacturer:** SANYO (now ON Semiconductor)  
2. **Type:** CMOS LSI (Large-Scale Integration)  
3. **Package:** SOP (Small Outline Package)  
4. **Operating Voltage:** Typically 2.7V to 5.5V (exact range may vary)  
5. **Communication Interface:** Serial I/O (I²C or similar)  
6. **Applications:** Used in automotive and consumer electronics, particularly in car audio systems (e.g., tuners, radio controls).  

### **Descriptions:**
- The LC72348W is designed for digital tuning and control in radio systems.  
- It integrates functions like frequency synthesis, PLL (Phase-Locked Loop), and microcontroller interfacing.  
- Optimized for low power consumption and high noise immunity.  

### **Features:**
1. **PLL Synthesizer:** Supports AM/FM tuning with high precision.  
2. **Serial Data Control:** Allows communication with a host microcontroller.  
3. **Built-in Prescaler:** Supports frequency division for RF input.  
4. **Low Standby Current:** Suitable for battery-operated devices.  
5. **Compact Design:** SOP package saves board space.  

For exact electrical characteristics and pin configurations, refer to the official datasheet from ON Semiconductor (formerly SANYO).
