Description and Introduction

16 KBIT (2KB X 8) ZEROPOWER SRAM The **M48Z12-70PC1** is a non-volatile static RAM (NVSRAM) module manufactured by **STMicroelectronics (STM)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Type:** NVSRAM (Non-Volatile Static RAM)  
- **Density:** 64 Kb (8 Kb × 8)  
- **Access Time:** 70 ns  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 28-pin DIP (Dual In-line Package)  
- **Data Retention:** 10 years minimum in non-volatile mode  
- **Endurance:** Unlimited read/write cycles in SRAM mode  

### **Descriptions:**
- Combines SRAM speed with non-volatile data storage.  
- Includes an integrated lithium energy source for data retention during power loss.  
- Automatically saves SRAM data to non-volatile storage upon power failure and restores it when power returns.  
- Ideal for applications requiring high-speed, non-volatile memory with frequent updates.  

### **Features:**
- **Automatic Store & Recall:** Transfers data between SRAM and non-volatile storage during power transitions.  
- **Zero Write Time:** No delay when storing data to non-volatile memory.  
- **High Reliability:** Built-in lithium cell ensures long-term data retention.  
- **Full SRAM Compatibility:** Works as a standard SRAM when powered.  
- **Industrial-Grade:** Suitable for embedded systems, automotive, and industrial applications.  

This module is commonly used in systems requiring fast, non-volatile memory with frequent updates, such as data logging, RAID controllers, and medical devices.

Application Scenarios & Design Considerations

16 KBIT (2KB X 8) ZEROPOWER SRAM

Alternative Part Number

  • DS1216E --: Nonvolatile controller with embedded lithium cell, functionally similar to the M48Z12 zero-power SRAM module and widely used as a drop-in style replacement in battery-backed SRAM designs.
  • BQ4011YMA-70 --: 70 ns nonvolatile SRAM module with integrated battery, matching the 70 ns access time and 5 V operation of the M48Z12-70PC1.
  • M48T02-70PC1 --: Same manufacturer TIMEKEEPER nonvolatile SRAM family with 70 ns speed and DIP package, offering a compatible pinout and timing for legacy designs.
  • DS1230Y-70 --: Nonvolatile SRAM module with integrated battery and 70ns speed grade, offering similar capacity and pin-compatible functionality for legacy nonvolatile memory applications.
