Description and Introduction

4 Mbit (512 Kbit x 8) ZEROPOWER® SRAM The M48Z512AV-85PM1 is a Non-Volatile SRAM (NVSRAM) manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Memory Type:** Non-Volatile SRAM (NVSRAM)  
- **Density:** 512 Kbit (64K 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)  
- **Data Retention:** 10 years minimum in non-volatile mode  
- **Standby Current (Battery Backup Mode):** 1 µA (typical)  
- **Active Current:** 25 mA (typical)  

### **Descriptions:**  
- Combines SRAM speed with non-volatile EEPROM backup.  
- Automatically stores data to EEPROM during power loss.  
- Includes an integrated lithium energy source for backup.  
- Suitable for applications requiring fast write speeds and non-volatility.  

### **Features:**  
- **High-Speed SRAM:** Fast read/write operations (85 ns access time).  
- **Non-Volatile Storage:** Data retention without power.  
- **Automatic Power-Fail Protection:** Saves data during power loss.  
- **Battery Monitor:** Detects low battery condition.  
- **Unlimited Write Cycles:** Unlike standalone EEPROM/Flash.  
- **JEDEC-Compatible Pinout:** Easy replacement for standard SRAMs.  
- **RoHS Compliant:** Meets environmental standards.  

This information is based on the manufacturer's datasheet for the M48Z512AV-85PM1.
