Description and Introduction

CMOS 2K x 8 zeropower SRAM, 200ns The **M48Z12-200PC1** is a non-volatile SRAM (NVSRAM) module manufactured by **STMicroelectronics (ST)**.  

### **Key Specifications:**  
- **Memory Type:** Non-Volatile SRAM (NVSRAM)  
- **Density:** 256Kb (32K × 8)  
- **Voltage Supply:** 4.5V to 5.5V  
- **Access Time:** 200ns  
- **Package:** 28-pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** 0°C to 70°C (Commercial)  
- **Data Retention:** 10 years minimum (non-volatile storage)  
- **Battery Backup:** Integrated lithium energy source for data retention  

### **Features:**  
- **Automatic Data Protection:** On power loss, data is automatically saved to non-volatile storage.  
- **Unlimited Write Cycles:** Unlike EEPROM or Flash, NVSRAM allows unlimited read/write operations.  
- **Fast Access Time:** 200ns read/write speed.  
- **Direct SRAM Replacement:** Compatible with standard SRAM pinouts.  
- **Self-Contained Backup:** No external battery or supercapacitor required.  

This module is commonly used in applications requiring fast, non-volatile memory with high endurance, such as industrial control systems, medical devices, and data logging equipment.

Application Scenarios & Design Considerations

CMOS 2K x 8 zeropower SRAM, 200ns

Alternative Part Number

  • DS1216E --: SmartWatch phantom clock module that provides equivalent nonvolatile timekeeping and RAM control functions for battery-backed SRAM designs, widely used as a functional substitute in legacy ST NVRAM applications.
  • BQ4011YMA-150 --: Integrated nonvolatile SRAM module with embedded battery and control circuitry, offering comparable 2Kx8 organization and access timing suitable for drop-in replacement in systems originally using the M48Z12 series.
  • M48T02-150PC1 --: TIMEKEEPER nonvolatile SRAM from the same vendor family with similar pinout and battery-backed retention, providing a close functional match when the exact M48Z12-200PC1 variant is unavailable.
