Description and Introduction

16 KBIT (2KB X 8) ZEROPOWER SRAM The **M48Z02-200PC1** is a **2Kbit (256 x 8) non-volatile static RAM (NVSRAM)** manufactured by **STMicroelectronics (STM)**.  

### **Key Specifications:**  
- **Memory Size:** 2 Kbit (256 x 8)  
- **Technology:** Non-Volatile SRAM (NVSRAM)  
- **Supply Voltage:** 4.5V to 5.5V  
- **Access Time:** 200 ns  
- **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  
- **Automatic Store on Power Loss:** Yes (with built-in energy storage capacitor)  

### **Features:**  
- Combines SRAM speed with non-volatile data retention  
- **Zero write time** in non-volatile store operation  
- **Unlimited read/write cycles** in SRAM mode  
- **Self-timed store cycle** initiated by power loss detection  
- **Lithium energy source** for data retention  
- **JEDEC-standard pinout** for easy replacement of EPROMs and EEPROMs  

This device is commonly used in applications requiring **fast SRAM performance with non-volatile backup**, such as **industrial controls, networking equipment, and data logging systems**.

Application Scenarios & Design Considerations

16 KBIT (2KB X 8) ZEROPOWER SRAM

Alternative Part Number

  • DS1225AD-200+ --: Nonvolatile SRAM module with 200 ns access time and 8Kx8 organization, functionally equivalent to the M48Z02 zero-power SRAM in a DIP package.
  • BQ4011YMA-200 --: 200 ns nonvolatile SRAM with integrated battery backup, same 8Kx8 density and pin-compatible DIP footprint, suitable drop-in replacement.
  • CY14B101PA-SFXI --: nvSRAM with comparable 8Kx8 organization and access timing; requires minor board adaptation but offers equivalent nonvolatile data retention.
  • DS1220AD-200 --: Pin-compatible 16K nonvolatile SRAM module with 200ns access time, direct functional replacement for the M48Z02 in most designs.
  • BQ4011YMA-150 --: Nonvolatile SRAM module with comparable organization and interface; faster 150ns access time provides margin while remaining socket-compatible.
  • DS1220AB-150 --: Same 2K x 8 nonvolatile SRAM family with 150ns speed grade; widely available alternate source for the M48Z02-200PC1.
