Description and Introduction

1 MBIT (128KB X 8) ZEROPOWER SRAM The **M48Z129V-85PM1** is a non-volatile SRAM (nvSRAM) manufactured by **STMicroelectronics (ST)**. Below are the key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Memory Type:** Non-Volatile SRAM (nvSRAM)  
- **Density:** 1 Mbit (128K x 8)  
- **Access Time:** 85 ns  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin PM (Plastic Module)  
- **Interface:** Parallel  
- **Data Retention:** 10 years minimum  
- **Endurance:** Unlimited read/write cycles  

### **Descriptions:**
- Combines **SRAM speed** with **non-volatile data storage** using an integrated **EEPROM backup**.  
- Automatically saves data to EEPROM during power loss and restores it upon power-up.  
- Suitable for applications requiring **high-speed, non-volatile memory** with **zero write delays**.  

### **Features:**
- **Zero write delay** (data written to SRAM and EEPROM simultaneously).  
- **Automatic store on power loss** (using an external capacitor).  
- **Unlimited SRAM read/write cycles**.  
- **High-speed access** (85 ns).  
- **Industrial temperature range** (-40°C to +85°C).  
- **Low-power CMOS technology**.  

This information is strictly based on STMicroelectronics' official documentation for the **M48Z129V-85PM1**.
