Description and Introduction

512 Bit (64B X8) Serial Access TIMEKEEPER SRAM The M41T56MH6E is a serial real-time clock (RTC) manufactured by STMicroelectronics (STM). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage:** 2.0V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Timekeeping Current:** 400nA (typical) at 3V  
- **Interface:** I²C (400kHz)  
- **Clock Accuracy:** ±5ppm (±0.432s/day) at 25°C  
- **Package:** SO8 (150mil)  

### **Descriptions:**
- The M41T56MH6E is a low-power serial RTC with a built-in 32.768kHz oscillator.  
- It provides timekeeping functions (seconds, minutes, hours, day, date, month, year) with leap-year compensation up to 2099.  
- Includes a programmable alarm and watchdog timer.  
- Features a power-fail detection circuit and automatic switchover to backup supply.  

### **Features:**
- **Ultra-Low Power Consumption:** 400nA typical timekeeping current.  
- **Battery Backup:** Operates from a backup supply when main power fails.  
- **I²C Interface:** Supports fast-mode (400kHz) communication.  
- **Clock Output:** Provides a programmable square-wave output (32.768kHz, 1Hz, etc.).  
- **Industrial Temperature Range:** Suitable for harsh environments.  
- **Small Footprint:** Available in an SO8 package.  

This device is commonly used in applications requiring accurate timekeeping, such as industrial systems, meters, and embedded systems.
