Description and Introduction

64 KBIT (8KB X 8) TIMEKEEPER SRAM The **M48T58Y-70MH1E** is a **Timekeeper SRAM** manufactured by **STMicroelectronics (STM)**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Non-volatile SRAM (NVSRAM) with a built-in real-time clock (RTC)  
- **Density:** 64 Kb (8 KB)  
- **Organization:** 8K x 8 bits  
- **Access Time:** 70 ns  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SOIC (MH)  

### **Descriptions:**  
- Integrates **SRAM**, a **real-time clock (RTC)**, and a **power-fail control circuit**.  
- **Battery-backed** to retain data and timekeeping during power loss.  
- **Automatic switchover** to battery power when main power fails.  
- **Century byte** for year 2000 compliance.  

### **Features:**  
- **Non-volatile SRAM** with **unlimited write cycles**.  
- **Real-time clock** with seconds, minutes, hours, day, date, month, and year.  
- **Low-power consumption** in battery backup mode.  
- **Industrial temperature range** (-40°C to +85°C).  
- **28-pin SOIC package** for surface-mount applications.  

This device is commonly used in **embedded systems, industrial controls, medical equipment, and data logging applications** where reliable timekeeping and data retention are critical.
