Description and Introduction

4Kbit, 2Kbit and 1Kbit Serial SPI Bus EEPROM With High Speed Clock The **M95040-WDW6TG** is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 4 Kbit (512 x 8 bits)  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Operating Voltage:** 1.8V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Write Cycle Time:** 5 ms (typical)  
- **Endurance:** 4 million write cycles  
- **Data Retention:** 200 years  
- **Package:** WDFN6 (2 x 3 mm, 6-lead)  

### **Descriptions:**
- The **M95040-WDW6TG** is a low-power, high-reliability EEPROM designed for embedded systems.  
- It supports SPI communication with clock frequencies up to **10 MHz**.  
- Features a **Write Protect (WP) pin** for hardware protection of memory blocks.  
- Includes a **software write protection** mechanism for partial or full array protection.  

### **Features:**
- **Low Power Consumption:**  
  - Standby current: 2 µA (typical)  
  - Active current: 1 mA (at 5 MHz)  
- **SPI Modes:** Supports modes 0 and 3.  
- **Page Write Buffer:** Allows up to 32 bytes to be written in a single operation.  
- **Industrial-Grade Reliability:** High endurance and long data retention.  
- **AEC-Q100 Qualified:** Suitable for automotive applications.  

This EEPROM is commonly used in automotive, industrial, and consumer electronics for storing configuration data, calibration settings, and other non-volatile parameters.
