Description and Introduction

1 MBIT (128KB X 8) ZEROPOWER SRAM The **M48Z128-70PM1** is a non-volatile static RAM (NVSRAM) manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Type:** Non-Volatile SRAM (NVSRAM)  
- **Density:** 128 Kb (16 K × 8 bits)  
- **Access Time:** 70 ns  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 32-pin PM (Plastic Module)  
- **Data Retention:** 10 years minimum (non-volatile storage)  
- **Write Cycle Endurance:** Unlimited (SRAM), 1 million cycles (EEPROM backup)  

### **Descriptions:**
- Combines high-speed SRAM with non-volatile EEPROM backup.  
- Automatically saves data to EEPROM on power loss and restores it on power-up.  
- Suitable for applications requiring fast read/write operations with non-volatile data retention.  

### **Features:**
- **Battery-Free Operation:** No external battery required for data retention.  
- **Automatic Store & Recall:** Data is saved during power failure and restored upon power restoration.  
- **High-Speed Access:** 70 ns access time for fast read/write operations.  
- **Low Power Consumption:** Standby current as low as 10 µA (typical).  
- **Industrial-Grade Reliability:** Available in extended temperature range options.  

This NVSRAM is commonly used in **industrial, medical, and embedded systems** where data integrity during power loss is critical.
