Description and Introduction

16Kbit, 8Kbit, 4Kbit, 2Kbit, 1Kbit and 256bit (8-bit or 16-bit wide) MICROWIRE Serial Access EEPROM The **M93C46-TMN6T** is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by **STMicroelectronics**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 1Kbit (128 x 8 or 64 x 16 organization)  
- **Interface:** Microwire (3-wire serial interface)  
- **Supply Voltage:** 1.8V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Write Time:** 5ms (typical)  
- **Endurance:** 4 million write cycles  
- **Data Retention:** 200 years  
- **Package:** TSSOP-8  

### **Descriptions:**
- The **M93C46-TMN6T** is a low-power EEPROM designed for applications requiring reliable non-volatile memory storage.  
- It supports both **8-bit and 16-bit** data organization, providing flexibility for different system requirements.  
- The **Microwire-compatible serial interface** simplifies integration with microcontrollers.  

### **Features:**
- **Low Power Consumption:**  
  - Standby current: 5µA (max)  
  - Active current: 2mA (max)  
- **Software & Hardware Write Protection:**  
  - Prevents accidental data corruption.  
- **Sequential Read Operation:**  
  - Allows faster data retrieval.  
- **Self-Timed Programming Cycle:**  
  - No external timing components required.  
- **Extended Temperature Range:**  
  - Suitable for industrial applications.  

This EEPROM is commonly used in **automotive, industrial, and consumer electronics** for parameter storage, calibration data, and configuration settings.
