Description and Introduction

Serial Access RTC with Alarms The M41T80M6F is a serial real-time clock (RTC) manufactured by STMicroelectronics. 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 (±0.432 seconds/day) from 0°C to +60°C  
- **Package:** SO8 (150mil)  

### **Descriptions:**
- The M41T80M6F is a low-power serial RTC with an integrated 32.768kHz oscillator.  
- It provides timekeeping functions (seconds, minutes, hours, day, date, month, year) with leap-year compensation up to 2099.  
- Features a built-in power-sense circuit for automatic switchover to backup supply (battery or supercapacitor).  
- Includes alarm, watchdog timer, and timestamp functions.  

### **Features:**
- **Ultra-Low Power Consumption:** Ideal for battery-backed applications.  
- **Battery Backup:** Automatic switchover to backup supply.  
- **Programmable Alarm & Interrupt:** Configurable for time/date-based triggers.  
- **Watchdog Timer:** Reset function for system monitoring.  
- **Timestamp Function:** Records power-up/down events.  
- **Oscillator Stability:** High accuracy over temperature variations.  

This device is commonly used in embedded systems, industrial controls, meters, and IoT applications requiring precise timekeeping.
