Description and Introduction

3.3V-5V TIMEKEEPER Supervisor The **M48T201Y-70MH1TR** is a **Timekeeper SRAM** manufactured by **STMicroelectronics (STM)**.  

### **Specifications:**  
- **Type:** Non-volatile SRAM (NVSRAM) with a built-in real-time clock (RTC)  
- **Density:** 256 Kbit (32K x 8)  
- **Access Time:** 70 ns  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 44-pin PLCC (Plastic Leaded Chip Carrier)  
- **Data Retention:** Minimum 10 years with power applied  
- **Clock Accuracy:** ±1 minute per month at 25°C  
- **Battery Backup:** Integrated lithium energy source  

### **Descriptions & Features:**  
- Combines **SRAM** and a **real-time clock (RTC)** in a single chip.  
- **Non-volatile memory** retains data during power loss.  
- **Automatic power-fail chip deselect** and **write protection**.  
- **Battery-backed operation** ensures continuous timekeeping.  
- **Industrial temperature range** for harsh environments.  
- **Low-power CMOS technology** for efficient operation.  
- **JEDEC-standard pinout** for compatibility with standard SRAMs.  

This device is commonly used in applications requiring **data logging, embedded systems, and real-time clock functions** with non-volatile memory backup.
