Description and Introduction

16Kbit, 8Kbit, 4Kbit, 2Kbit and 1Kbit (8-bit or 16-bit wide) MICROWIRE Serial Access EEPROM The **M93C56-WMN6TP** is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by **STMicroelectronics**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 16 Kbit (2 Kbyte) organized as 128 x 16-bit or 256 x 8-bit.
- **Interface:** Microwire (3-wire serial interface).
- **Supply Voltage:**  
  - **Operating:** 2.5V to 5.5V  
  - **Standby:** 1.8V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Write Time:** 5 ms (typical).  
- **Endurance:** 4 million write cycles per byte.  
- **Data Retention:** 200 years.  
- **Package:** SO-8 (MN).  

### **Descriptions:**
- The M93C56-WMN6TP is a **non-volatile memory** that retains data even when power is removed.  
- It supports both **16-bit and 8-bit** organization modes.  
- Features a **sequential read operation** for faster data access.  
- Includes **write protection** via software control.  

### **Features:**
- **Low Power Consumption:**  
  - Active current: 3 mA (max)  
  - Standby current: 10 μA (max)  
- **Serial Interface:** Compatible with Microwire protocol.  
- **Software Protection:** Write operations can be disabled via a specific command.  
- **Self-Timed Programming Cycle:** No external timing components required.  
- **High Reliability:** Industrial-grade temperature range and long data retention.  

This EEPROM is commonly used in automotive, industrial, and consumer electronics applications for storing configuration data.
