Description and Introduction

3.3V-5V TIMEKEEPER CONTROLLER The **M48T212V85MH1E** is a Timekeeping RAM (TKRAM) device manufactured by **STMicroelectronics (STM)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:**  
- **STMicroelectronics (STM)**  

### **Specifications:**  
- **Type:** Non-volatile SRAM (NVSRAM) with real-time clock (RTC)  
- **Density:** 16Kb (2K x 8)  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin SOIC (MH)  
- **Clock Accuracy:** ±1 minute per month at 25°C  
- **Battery Backup:** Integrated lithium energy source  
- **Data Retention:** Minimum 10 years in the absence of power  
- **Access Time:** 85ns  

### **Descriptions:**  
- Combines SRAM with a real-time clock (RTC) and power-fail control circuitry.  
- Non-volatile operation ensures data retention during power loss.  
- Integrated lithium battery maintains clock and RAM data for extended periods.  

### **Features:**  
- **Automatic Power-Fail Chip Deselect:** Protects data during power loss.
