Description and Introduction

64 Kbit 8Kb x 8 ZEROPOWER SRAM The M48Z18-100MH1 is a non-volatile SRAM (NVSRAM) manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Memory Type:** Non-Volatile SRAM (NVSRAM)  
- **Density:** 256Kb (32K x 8)  
- **Access Time:** 100ns  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:**  
  - Commercial: 0°C to +70°C  
  - Industrial: -40°C to +85°C  
- **Package:** 28-pin DIP (Dual In-line Package)  
- **Data Retention:** Minimum 10 years in non-volatile mode  
- **Write Endurance:** Unlimited (SRAM), 1 million cycles (EEPROM backup)  

### **Descriptions:**  
- Combines SRAM with non-volatile EEPROM backup for data retention during power loss.  
- Automatically stores SRAM data to EEPROM when power fails and restores it upon power-up.  
- No external battery required for data retention.  

### **Features:**  
- **Non-Volatile Storage:** EEPROM backup ensures data integrity during power interruptions.  
- **Fast Access Time:** 100ns read/write speed.  
- **Low Power Consumption:**  
  - Active current: 50mA (typical)  
  - Standby current: 20μA (typical)  
- **Automatic Store & Recall:** Hardware-controlled data backup and restore.  
- **Unlimited SRAM Write Cycles:** No wear-out mechanism for SRAM operations.  
- **High Reliability:** Industrial-grade temperature range available.  
- **RoHS Compliant:** Meets environmental standards.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

64 Kbit 8Kb x 8 ZEROPOWER SRAM

Alternative Part Number

  • DS1225AD-100 --: Nonvolatile SRAM module with the same 8Kx8 organization and 100 ns access time, pin-compatible with the M48Z18 and widely used as a drop-in replacement.
  • BQ4011YMA-100 --: Battery-backed nonvolatile SRAM in the same 8Kx8 density and 100 ns speed grade, offering comparable function and interface for replacement.
  • CY14B101PA-SFXI --: nvSRAM with equivalent 8Kx8 storage and similar parallel interface, suitable when a modern nonvolatile SRAM alternative is acceptable.
