Description and Introduction

DTS Microcontroller (DTS-21) The TC9327AF is a CMOS LSI (Large-Scale Integration) chip designed for remote control transmitter applications. Below are its key specifications, descriptions, and features:  

### **Manufacturer:**  
Toshiba  

### **Specifications:**  
- **Supply Voltage:** 2.2V to 3.6V (low-voltage operation)  
- **Operating Temperature Range:** -20°C to +70°C  
- **Oscillation Frequency:** 455 kHz (ceramic resonator)  
- **Output Type:** Open-drain output (for infrared LED drive)  
- **Package:** SOP (Small Outline Package), 16-pin  

### **Descriptions:**  
- The TC9327AF is a remote control encoder IC that generates modulated signals for infrared (IR) transmission.  
- It supports multiple key inputs (up to 32 keys with a matrix configuration).  
- Includes a built-in oscillator circuit for generating the carrier frequency (typically 38 kHz).  
- Features power-saving modes to reduce current consumption when idle.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **Custom Code Functionality:** Allows setting a manufacturer-specific ID to prevent interference.  
- **Auto Power-Off:** Automatically enters standby mode after transmission.  
- **Key Input Matrix:** Supports 4x8 or 5x7 key configurations.  
- **Modulation Output:** Provides a modulated signal for driving an IR LED.  

This information is based on the manufacturer's datasheet and technical documentation.
